(1) Estimated in accordance with Rule 457(c) solely for the purpose of
    computing the amount of the registration fee based on the average of the
    high and low prices of the Company's Common Stock as reported on the 
    Nasdaq National Market System on July 8, 1997.

(2) Issuable upon conversion of the 5% Convertible Subordinated Debenture of 
    the Company (the "Debentures"). For purposes of estimating the number of 
    shares of Common Stock to be included in the Registration Statement the 
    Company calculated the number of shares of Common Stock issuable upon 
    conversion of the Debentures using a conversion price at the time of such 
    conversion of $8.33-1/3 per share which is below the conversion price 
    as of July 11, 1997 ($17.75 per share) and was arbitrarily selected. 
    In addition to the shares set forth in the table, the amount to be 
    registered includes an indeterminate number of shares issuable upon 
    conversion of or in respect of the debentures, as such number may be 
    adjusted as a result of stock splits, stock dividends and antidilution 
    provisions (including floating rate conversion prices) in accordance 
    with Rule 416.

   THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT THAT SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(a),

PROSPECTUS
                                   3,061,401 SHARES

                                  ZITEL CORPORATION

                                  ----------------
                                    COMMON STOCK
                                  ----------------

    This Prospectus relates to a total of 3,061,401 shares of Common Stock 
(the "Shares") (the "Common Stock") of Zitel Corporation (the "Company") 
which are being offered and sold by certain stockholders of the Company (the 
"Selling Securityholders").  Of such Shares (i) 61,401 were issued by the 
Company in connection with the acquisition of Palmer & Webb Systems, BV, and 
(ii) up to 3,000,000 are issuable pursuant to the conversion of 5% 
Convertible Subordinated Debentures of the Company (the "Debentures"). The 
Debentures, with accrued interest thereon, are convertible into Common Stock 
at a price equal to 90% of the average low trading price of the Common Stock 
for the five trading days preceding the date of conversion, but in no event 
greater than $26.975 per share; accordingly, the number of shares issuable 
upon conversion could be greater or less than 3,000,000. An aggregate of 
$25,000,000 of Debentures was sold to four institutional investors who are 
Selling Securityholders. In connection with the acquisition and with the 
private placement of the Debentures the Company agreed to register the resale 
of the Common Stock into which the Debentures are convertible.

    The Shares may be offered by the Selling Securityholders or certain 
pledgees, donees, transferees or other successors in interest from time to 
time in long or short transactions on the Nasdaq National Market System, in 
privately negotiated transactions, through the writing or exercise of 
options, or a combination of such methods of sale, at fixed prices that may 
be changed, at market prices prevailing at the time of sale, at prices 
related to such prevailing market prices or at negotiated prices.  The 
Selling Securityholders may effect such transactions by selling the Shares to 
or through broker-dealers, and such broker-dealers may receive compensation 
in the form of discounts, concessions or commissions from the Selling 
Securityholders or the purchasers of the Shares for whom such  broker-dealers 
may act as agent or to whom they sell as principal or both (which 
compensation to a particular broker-dealer might be in excess of customary 
commissions).  See "Selling Securityholders" and "Plan of Distribution."

    The Company will not receive any of the proceeds from the sale of the 
Shares by the Selling Securityholders hereof.  See "Plan of Distribution."

    The Selling Securityholders, directly or through agents, dealers or 
underwriters, may sell the Shares offered hereby from time to time on terms 
to be determined at the time of sale.  The Company's Common Stock is traded 
on the Nasdaq National Market System under the symbol ZITL.                   

                             ----------------

         THE SHARES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.
                       SEE "RISK FACTORS" ON PAGE 5.

                             ----------------

         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
           SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
           COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION
               OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
                 ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY
                      REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

    No underwriting commissions or discounts will be paid by the Company in 
connection with this offering.  Estimated expenses payable by the Company in 
connection with this offering are $40,000.  The aggregate proceeds to the 
Selling Securityholders from the sale of the Shares will be the purchase 
price of the Shares sold less the aggregate agents' commissions and 
underwriters' discounts, if any, and other expenses of issuance and 
distribution not borne by the Company.  See "Plan of Distribution."

    The Selling Securityholders and any broker-dealers, agents or 
underwriters that participate with the Selling Securityholders in the 
distribution of the Shares may be deemed to be "underwriters" within the 
meaning of the Securities Act of 1933, as amended (the "Act"), and any 
commission received by them and any profit on the resale of the Shares 
purchased by them may be deemed to be underwriting commissions or discounts 
under the Act.  The Company has agreed to indemnify the Selling 
Securityholders and certain other persons against certain liabilities, 
including liabilities under the Act.

               The date of this Prospectus is July __, 1997.

                                  THE COMPANY

    Zitel Corporation was incorporated in California in 1979.  The Company's 
executive offices are located at 47211 Bayside Parkway, Fremont, California 
94538-6517, and its telephone number is (510) 440-9600.

                                USE OF PROCEEDS

    The Company will not receive any of the proceeds from the sale of the 
Shares by the Selling Securityholders.

                                DIVIDEND POLICY

    The Company has never paid cash dividends.  The Company's Board of 
Directors currently intends to retain any earnings for use in the Company's 
business and does not anticipate paying any cash dividends in the foreseeable 
future.  The Company's 5% Convertible Subordinated Debentures and the 
Company's bank credit agreement prohibit the payment of dividends.

                                 RISK FACTORS

    AN INVESTMENT IN THE COMPANY INVOLVES A HIGH DEGREE OF RISK.  THE 
FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY BEFORE PURCHASING THE 
COMMON STOCK OFFERED HEREBY.

RECENT LEVELS OF NET SALES; DEPENDENCE ON ROYALTY REVENUE

    In recent years the Company has not generated net sales sufficient to 
produce an operating profit and has relied on a stream of royalty payments 
under an agreement with IBM to support its activities.  These royalties 
amounted to $15,421,000 in fiscal 1995 and $14,473,000 in fiscal 1996.  In 
late 1996 IBM introduced a new version of the royalty bearing device with 
substantially greater capacity and royalty revenue declined to $2,318,000 in 
the first quarter of fiscal 1997 and $1,196,000 in the quarter ended March 
31, 1997.  The Company believes that IBM is transitioning to a device which 
does not require royalty payments to the Company, and that as a result 
royalty revenue will continue to decline.  The Company has sustained 
operating losses and net losses in the quarters ended December 31, 1996 and 
March 31, 1997. In the most recent quarter the Company realized a negative 
net margin on net sales.  The Company must generate substantial additional 
net sales of its hardware products in order to restore gross margins on those 
products, must generate profitable revenue from its recently acquired 
software businesses and must generate revenue from its new systems solutions 
division in order to remain a viable operating entity.  There is no assurance 
that the Company can achieve those objectives.

FLUCTUATIONS IN QUARTERLY RESULTS

    The Company's quarterly operating results have in the past varied and may 
in the future vary significantly depending on a number of factors, including: 
the level of competition, the size, timing, cancellation or rescheduling of 
significant orders; product configuration and mix; market acceptance of new 
products and product enhancements; new product announcements or introductions 
by the Company's competitors; deferrals of customer orders in anticipation of 
new products or product enhancements; changes in pricing by the Company or 
its competitors; the impact of price protection measures and return 
privileges granted by the Company to its distributors and value added 
resellers (VARs); the ability of the Company to develop, introduce and market 
new products and product enhancements on a timely basis; hardware component 
costs and availability, particularly with respect to hardware components 
obtained from sole source suppliers; hardware supply constraints; the 
Company's success in expanding its sales and marketing programs; 
technological changes in the market for the Company's products, product mix 
and the mix of sales among the Company's sales channels; levels of 
expenditures on research and development; changes in the Company's strategy; 
personnel changes; general economic trends and other factors.

    Sales for any quarter are not predictable with any significant degree of
certainty.  The Company generally operates with limited order backlog because
its products typically are shipped shortly after orders are received.  Sales 


                                      5.

to a single customer in a quarter have affected and may affect net sales and 
operating margins.  As a result, sales in any quarter are generally dependent 
on orders booked and shipped in that quarter.  Sales are also difficult to 
forecast because the Company has not as yet generated significant sales of 
its products incorporating cache activated storage device (CASD) technology.  
Due to the typical timing of customer orders, the Company often ships 
products representing a significant portion of its net sales for a quarter 
during the last month of that quarter.  Any significant deferral of these 
sales could have a material adverse effect on the Company's results of 
operations in any particular quarter. To the extent that the Company 
completes significant sales earlier than expected, operating results for 
subsequent quarters may be adversely affected. The Company's expense levels 
are based, in part, on its expectations as to future sales.  As a result, if 
sales levels are below expectations, net income may be disproportionately 
affected.

    The mix of the products marketed by the Company has been evolving over 
the last three years, and the Company's net sales have declined over that 
period. Due to all of the foregoing factors, the Company believes that 
period-to-period comparisons of its results of operations are not necessarily 
meaningful and should not be relied upon as an indicator of future 
performance.  It is possible that in some future quarter the Company's 
operating results may be below the expectations of public market analysts and 
investors.  In such event, the price of the Company's Common Stock would 
likely be materially and adversely affected.

INVESTMENT IN MATRIDIGM

    The Company has invested $5,588,000 to acquire an approximate 30% 
interest in MatriDigm Corporation ("MatriDigm"), a private company organized 
to provide software maintenance and re-engineering services for users of IBM 
mainframe computer systems.  MatriDigm has initially focused on development 
of a set of automated tools to identify and specifically modify dates within 
IBM COBOL programs to bring them into compliance with the Year 2000 
requirements and to test the modified programs.  MatriDigm in February 1997 
announced commercial availability of an automated tool set for a pac-binary 
solution for programs written in ANSI COBOL 85 and, to respond to market 
demand, has recently announced commercial availability of a windowing 
solution.  MatriDigm intends to continue to refine its current tool set and 
to extend its tool set to modify other COBOL languages as well as other 
computer languages widely used to write programs for IBM mainframe computers. 
Industry sources report a multi-billion dollar demand for services such as 
those being developed by MatriDigm and an automated tool set should provide 
greater profit margins than can be realized using other available methods.  
However, MatriDigm has not realized revenue as yet, and there is no assurance 
that it can successfully market its automated tool set, develop extensions 
for other computer languages or generate substantial revenue and profits. 
During the course of development, the Company has made additional investments 
in MatriDigm and may be required to make additional investments in the future.

VOLATILITY OF STOCK PRICE

    The price of the Company's Common Stock has been subject to extreme 
volatility over the past nine months, as the closing bid price has ranged 
between a low of 5-1/8 and a high of 61-1/4, with a recent price of 19.  The 
Company believes that the principal reasons for this volatility are rumored 
progress of and rumored problems in the product development program of 
MatriDigm.  MatriDigm, which expects to provide an automated solution to the 
Year 2000 problem, is a private company and the principal vehicle for public 
participation in ownership of MatriDigm is indirectly through ownership of 
Common Stock of the Company.  MatriDigm has been unable or unwilling to 
provide public information on a regular basis about the status of its 
development effort, and as a result an opportunity is presented for third 
parties to initiate rumors which result in significant swings in the price of 
the Company's Common Stock.  Until MatriDigm successfully develops a solution 
and generates significant sustained revenue, it will remain difficult for 
investors to apply standard methods of analysis to the value of the Company's 
investment in MatriDigm and the pattern of volatility should be expected to 
continue.

COMPETITION

    The data storage market is intensely competitive, with technological 
advances fueling continuous erosion of prices for data storage capacity.  The 
Company competes with much larger independent companies such as EMC Corp and 
Data General Corporation as well as manufacturers of computer systems such as 
Unisys Corporation, Sun Microsystems, Inc. and Hewlett-Packard Corporation. 
Many of its competitors have substantially greater financial resources and 
installed bases than the Company and, on account of their substantially 
higher level of purchases, are able to achieve significantly lower prices 
from suppliers of component parts.  While the Company believes that its CASD 
products are currently superior to competitive products, unless it can 
significantly increase the level of net sales and additional cost savings on 
component purchases, it will be unable to generate adequate gross margins on 
its CASD products.  There can be no assurance that the Company will be able 
to generate the level of net sales to achieve adequate gross margins.

    The market for Year 2000 services is intensely competitive, with services 
being provided by a number of national, regional and local firms, many of 
which have existing relationships and contractual arrangements with 
customers.  Many of these competitors have substantially greater financial, 
technical and marketing resources than the Company and MatriDigm.  The 
ability of the Company and MatriDigm to compete in this market will depend on 
the ability of MatriDigm to develop a successful automated solution and as 
yet there can be no assurance that MatriDigm will be successful in this 
effort.  In addition, the Company must attract and retain qualified personnel 
in which are also highly sought by its competition and must successfully 
leverage its own resources with contract and partnering relationships with 
other companies, including companies which are also competitors.

    The market for system management tools in which the Company's software 
products division competes is intensely competitive.  Many of the companies 
with which the Company competes, such as Hewlett-Packard Corporation, 
Computer Associates and BGS, Inc. have substantially larger installed bases 
and greater financial resources than the Company.

DEPENDENCE ON NEW PRODUCTS; RAPID TECHNOLOGICAL CHANGE

    The markets in which the Company operates are characterized by rapid 
technological change, changing customer needs, frequent new product 
introductions and evolving industry standards.  The introduction of products 
embodying new technologies, increased storage capacities by the Company's 
competitors and the emergence of new industry standards could render the 
Company's existing hardware products obsolete and unmarketable.  The 
Company's future success will depend upon its ability to develop and to 
introduce new products on a timely basis that keep pace with technological 
developments and emerging industry standards and address the increasingly 
sophisticated needs of its customers.  The Company has not as yet realized 
significant sales of its CASD products.  There can be no assurance that the 
Company will be successful in generating significant sales of these products. 
The failure of the Company to achieve significant net sales from these 
products could have a material adverse effect on the Company's business, 
operating results and financial condition. There can be no assurance that the 
Company will be successful in developing and marketing any other products 
that respond to technological changes or evolving industry standards, that 
the Company will not experience difficulties that could delay or prevent the 
successful development, introduction and marketing of new products, or that 
its new products will adequately meet the requirements of the marketplace and 
achieve market acceptance.  If the Company is unable, for technological or 
other reasons, to develop and introduce new products in a timely manner in 
response to changing market conditions or customer requirements, the 
Company's business, operating results and financial condition will be 
materially and adversely affected.

PRODUCT LIABILITY

    The Company's standard warranty provides that, if the Company's product 
does not function to published specifications, the Company will repair or 
replace the defective component without charge.  Although to date the 
Company's suppliers of hardware components have generally covered the 
warranty costs associated with such components, there can be no assurance 
that such manufacturers will continue to be willing or able to cover such 
costs, and their failure to do so would result in such costs being borne by 
the Company.  There can be no assurance that the 


                                      7.
<PAGE>

Company's warranty costs will not be significant in the future.  Significant 
warranty costs could have a material adverse effect on the Company's 
business, operating results or financial condition.

    The Company's agreements with its customers typically contain provisions 
intended to limit the Company's exposure to potential product liability 
claims. It is possible that the limitation of liability provisions contained 
in the Company's agreements may not be effective.  Although the Company has 
not received any product liability claims to date, the sale and support of 
products by the Company and the incorporation of products from other 
companies may entail the risk of such claims.  A successful product liability 
claim against the Company could have a material adverse effect on the 
Company's business, operating results and financial condition.

DEPENDENCE ON PROPRIETARY TECHNOLOGY

    The Company's success depends significantly upon its proprietary 
technology.  The Company currently relies on a combination of patent, 
copyright and trademark laws, trade secrets, confidentiality agreements and 
contractual provisions to protect its proprietary rights.  The Company seeks 
to protect its software, documentation and other written materials under 
trade secret and copyright laws, which afford only limited protection.  The 
Company has registered its Zitel, CASD, VAM and Datametrics trademarks and 
will continue to evaluate the registration of additional trademarks as 
appropriate.  The Company generally enters into confidentiality agreements 
with its employees and with key vendors and suppliers.  The Company currently 
has eight United States patents associated with its CASD technology.  There 
can be no assurance that these patents will provide the Company with any 
competitive advantages or will not be challenged by third parties, or that 
the patents of others will not have a material adverse effect on the 
Company's ability to do business.  The Company believes that the rapidly 
changing technology in the computer storage industry makes the Company's 
success depend more on the technical competence and creative skills of its 
personnel than on patents.

    There has also been substantial litigation in the computer industry 
regarding intellectual property rights, and litigation may be necessary to 
protect the Company's proprietary technology.  The Company has not received 
significant claims that it is infringing third parties' intellectual property 
rights, but there can be no assurance that third parties will not in the 
future claim infringement by the Company with respect to current or future 
products, trademarks or other proprietary rights.  The Company expects that 
companies in the storage systems market will increasingly be subject to 
infringement claims as the number of products and competitors in the 
Company's target markets grows. Any such claims or litigation may be 
time-consuming and costly, cause product shipment delays, require the Company 
to redesign its products or require the Company to enter into royalty or 
licensing agreements, any of which could have a material adverse effect on 
the Company's business, operating results or financial condition.  Despite 
the Company's efforts to protect its proprietary rights, unauthorized parties 
may attempt to copy aspects of the Company's products or to obtain and use 
information that the Company regards as proprietary.  There can be no 
assurance that the Company's means of protecting its proprietary rights will 
be adequate or that the Company's competitors will not independently develop 
similar technology, duplicate the Company's products or design around patents 
issued to the Company or other intellectual property rights of the Company.

INTERNATIONAL SALES AND OPERATIONS

    Sales to customers outside the United States have accounted for 
significant portions of the Company's net sales, and the Company expects that 
the recent acquisition of companies headquartered and operating in the United 
Kingdom and the Netherlands, respectively, will result in international sales 
representing an increasingly significant portion of the Company's net sales.  
International sales pose certain risks not faced by companies that limit 
themselves to domestic sales.  Fluctuations in the value of foreign 
currencies relative to the U.S. dollar, for example, could make the Company's 
products less price competitive and, if the Company in the future denominates 
any of its sales in foreign currencies, result in losses from foreign 
currency transactions. International sales also could be adversely affected 
by factors beyond the Company's control, including the imposition of 
government controls, export license requirements, restrictions on technology 
exports, changes in tariffs and taxes and general economic and political 
conditions.  The laws of some countries do not protect the Company's 
intellectual property rights to the same extent as the laws of the United 
States.


                                      8.

RECENT ACQUISITIONS

    The Company, on June 30, 1997, concluded the acquisition of the assets or 
stock of three companies:  Datametrics Systems Corporation, headquartered in 
Fairfax, Virginia; Palmer & Webb Systems, Limited, headquartered in England 
and Palmer & Webb Systems, B.V., headquartered in the Netherlands.  The 
operations of these acquired companies are substantial in relation to the 
previous operations of the Company and there are significant risks involved 
in integrating the operations and financial systems of these companies, in 
part because of the relative size of the acquired operations and the distance 
of the headquarters of these companies from the headquarters of the Company. 
Acquisitions involve a number of special risks, including diversion of 
management's attention, failure to retain key acquired personnel, 
unanticipated events or circumstances, legal liabilities and amortization of 
acquired intangible assets, some or all of which could have a material 
adverse effect on the Company's results of operations and financial 
condition.  Client satisfaction or performance problems at a single acquired 
firm could have a material adverse impact on the reputation of the Company as 
a whole.

    While the Company has had experience developing and marketing software, a 
substantial majority of the Company's efforts and experience have been 
devoted to the development, manufacturing and marketing of computer memory 
systems and embedded software and firmware.  The new focus on developing and 
marketing software will involve new and different skills and there can be no 
assurance that the Company will be successful in that effort.

DEPENDENCE ON KEY PERSONNEL

    The Company's future performance depends in significant part upon the 
continued service of its key technical and senior management personnel.  The 
Company provides incentives such as salary, benefits and option grants (which 
are typically subject to vesting over four years) to attract and retain 
qualified employees.  The loss of the services of one or more of the 
Company's officers or other key employees could have a material adverse 
effect on the Company's business, operating results and financial condition.  
The Company's future success also depends on its continuing ability to 
attract and retain highly qualified technical and management personnel.  
Competition for such personnel is intense, and there can be no assurance that 
the Company can retain its key technical and management employees or that it 
can attract, assimilate and retain other highly qualified technical and 
management personnel in the future.

    The future success of the Company's systems solutions division will 
depend to a significant extent on its ability to attract, train, motivate and 
retain highly skilled software development professionals, particularly 
project managers, software engineers and other senior technical personnel.  
The Company believes that in the United States and elsewhere there is a 
shortage of, and significant competition for, software development 
professionals with the advanced technological skills necessary to perform the 
services offered by the systems solutions division.  The increasing 
recognition of the scope and significance of the year 2000 problem has 
materially increased the competition for personnel with appropriate skills 
and salary requirements have increased as availability of such personnel has 
decline precipitously.  The Company's ability to maintain and renew existing 
relationships and obtain new business depends, in large part, on its ability 
to hire and retain technical personnel with the information technology skills 
who keep pace with continuing changes in information processing technology, 
evolving industry standards and changing client preferences.  An inability to 
hire such additional qualified personnel could impair the ability of the 
systems solutions division to manage and complete its existing projects and 
to bid for or obtain new projects.  Further, the Company must train and 
manage its growing employee base, requiring an increase in the level of 
responsibility for both existing and new management personnel.  There can be 
no assurance that the management skills and systems currently in place will 
be adequate or that the Company will be able to assimilate new employees 
successfully.  Accordingly, there can be no assurance that the Company will 
be successful in retaining current or future employees.

DILUTION FROM 5% CONVERTIBLE SUBORDINATED DEBENTURES

    The Company's 5% Convertible Subordinated Debentures (the "Debentures") 
(and accrued interest) are convertible at any time at the option of the 
holders thereof into Common Stock at a conversion price equal to the lesser 
of (a) 90% of the average low trading price of the Common Stock on the five 
trading days preceding the date of conversion or $26.975. In addition, 
certain penalties may have the effect of increasing the amounts convertible 
into Common Stock. If converted on July 11, 1997 the Debentures would have 
been convertible into approximately 1,408,253 shares of Common Stock (not 
including shares of Common Stock issuable upon conversion with respect to 
accrued interest on the Debentures) but this number of shares could prove to 
be significantly greater in the event of a decrease in the trading price of 
the Common Stock. Purchasers of Common Stock could therefore experience 
substantial dilution of their investment upon conversion of the Debentures.

ANTI-TAKEOVER PROVISIONS

    Certain provisions of the Company's Certificate of Incorporation, as 
amended and restated, and Bylaws, as amended, California law and the 
Company's indemnification agreements with certain officers and directors of 
the Company may be deemed to have an anti-takeover effect.  Such provisions 
may delay, defer or prevent a tender offer 


                                      9.
<PAGE>

or takeover attempt that a stockholder might consider to be in that 
stockholder's best interests, including attempts that might result in a 
premium over the market price for the shares held by stockholders.

    The Company's Board of Directors may issue additional shares of Common 
Stock or establish one or more classes or series of Preferred Stock, having 
the number of shares designations, relative voting rights, dividend rates, 
liquidation and other rights, preferences and limitations as determined by 
the Board of Directors without stockholder approval.

    The Board of Directors of the Company has approved the adoption of a 
Preferred Share Purchase Rights Plan (the "Rights Plan").  Terms of the 
Rights Plan provide for a dividend distribution of one preferred share 
purchase right (a "Right") for each outstanding share of common stock, no par 
value per share (the "Common Shares"), of the Company.  Each Right entitles 
the registered holder to purchase from the Company one one-hundredth of a 
share of Series A Junior Participating Preferred Stock, no par value (the 
"Preferred Stock"), at an exercise price of $69.50 per one one-hundredth of a 
Preferred Share (the "Purchase Price"), subject to adjustment, and a 
redemption price of $.01 per Right.  Each one one-hundredth of a share of 
Preferred Stock has designations and the powers, preferences and rights, and 
the qualifications, limitations and restrictions which make its value 
approximately equal to the value of a Common Share.

    The Rights are not exercisable until the earlier to occur of (i) 10 days 
following a public announcement that a person, entity or group of affiliated 
or associated persons (an "Acquiring Person") have acquired beneficial 
ownership of 15% or more of the outstanding Common Shares or (ii) 10 business 
days (or such later date as may be determined by action of the Board of 
Directors prior to such time as any person or entity becomes an Acquiring 
Person) following the commencement of, or announcement of an intention to 
make, a tender offer or exchange offer the consummation of which would result 
in the beneficial ownership by a person or group of 15% or more of such 
outstanding Common Shares.

    The Rights have certain anti-takeover effects as they would cause 
substantial dilution to a person or group that attempted to acquire the 
Company on terms not approved by the Company's Board of Directors.  The 
Rights should not interfere with any merger or other business combination 
approved by the Board of Directors, since the Rights may be redeemed by the 
Company at $.01 per Right prior to the earliest of (i) the twentieth day 
following the time that a person or group has acquired beneficial ownership 
of 15% or more of the Common Shares (unless extended for one or more 10 day 
periods by the Board of Directors), (ii) a change of control, or (iii) the 
final expiration date of the rights.

                                  THE COMPANY

BUSINESS

    Zitel Corporation ("Zitel" or the "Company") develops, markets and 
supports a wide range of data management solutions in the form of high 
performance storage technology and software products for performance 
monitoring, analysis and modeling.  The Company provides solution services 
for the year 2000 century date conversion opportunity through expanded 
product and service offerings and representing MatriDigm Corporation's 
MAP2000 factory conversion service.  The Company has three divisions:

    The storage division develops, manufactures and markets products based on 
proprietary Cached Actuator Storage Device (CASD) technology.  CASD was the 
basis for the joint development agreement with IBM that resulted in IBM's 
RAMAC storage product line.  The Company has received eight United States 
patents on the CASD technology and others are in process.  The value of the 
Company's products incorporating CASD technology is the result of proprietary 
caching algorithms, embedded intelligence and retentive learning, which 
provide a unique probablistic, predictive caching storage solution for high 
performance applications needs.

    The software products division is the combination of the recently 
acquired Datametrics Systems Corporation and Palmer & Webb Systems companies, 
with the Company's performance & modeling software products.  The combined 
subsidiaries operate under the Datametrics Systems name.  The division's 
product line is composed of a suite of systems with data management, 
monitoring, analysis, modeling and control capabilities for mainframe 
computers, open systems servers and distributed network systems.  These 
products are also used in the marketing of storage division products, and may 
have applications in the services provided by solutions services division.

    The solution services division provides Year 2000 conversion services, 
including project management, planning, analysis, code conversion, and 
testing. Zitel's primary code conversion methodology is based on the 
MatriDigm MAP2000 process for Cobol.  In addition, as a solution provider, 
Zitel utilizes other tools and processes to meet customer needs in different 
environments.  Zitel serves its Year 2000 customers both directly, with its 
own consulting staff, and through a teaming program where Zitel may be the 
subcontractor or partner to other solution providers worldwide.

    In 1992, the Company entered into a joint development agreement with 
International Business Machines Corporation ("IBM").  In September and 
October of 1994, IBM announced general availability of RAMAC products, which 
incorporate Zitel technology, and upon which the Company is receiving 
royalties based on RAMAC products sold.  In October 1995 and September 1996, 
IBM announced the general availability of RAMAC 2 and RAMAC 3, respectively, 
its second and third generation of RAMAC, which continues to include Zitel 
technology and upon which Zitel will receive royalties.  Royalties from RAMAC 
products constituted 38%, 65% and 63% of total revenue in fiscal 1994, 1995 
and 1996, respectively, and 42% in the first two quarters of fiscal 1997.

DATA STORAGE PRODUCTS

    The Company offers a family of rotating memory systems utilizing the CASD 
technology for use with Unisys A and V mainframe computers and with most 
UNIX, NT, Open VMS and NETWARE server platforms.  CASD-II, the second 
generation of the Company's CASD products, was introduced in September, 1995. 
CASD products integrate a high-capacity solid state cache with multiple 
rotating disk drives and utilize interactive caching algorithms.  Modules 
utilizing the technology are available with cache sizes ranging from 64 to 
512 megabytes and with one to four disk drives with capacities from 3.0 to 
36.4 gigabytes, depending on the market the products are sold into.  These 
modules can be sold on an individual module basis or are available in cabinet 
configurations ranging from one to six modules and up to 218 gigabytes per 
cabinet.  Pricing for a single module ranges from approximately $17,400 to 
$41,500.  Subsystems incorporating CASD technology are available in prices 
from $ 24,400 to $256,000 depending on the number of modules utilized, the 
amount of cache utilized, optional equipment, and other factors.

SOFTWARE PRODUCTS

    The Company's software products division offers a suite of products 
utilized for data management, monitoring, analysis and control of mainframe 
computers, open systems servers and distributed network systems.  These 
products are utilized by corporate customers with significant investments in 
management information systems to maximize efficiency of existing systems and 
plan system enhancements.  These products function with IBM VMS, Digital VMS, 
Unisys proprietary platforms as well as a wide variety of open systems 
platforms.  The principal products of the division are the following:

    VAM/Capacity Planner is a Windows-based system modeling tool that reduces 
analyses and planning costs by enabling companies to correctly identify 
current system utilization and undertake sophisticated analyses of 
modifications in system deployment or design.  VAM/Capacity Planner's 
embedded expertise allows easy examination of the effects of various 
configuration changes and determines the best equipment enhancements.  This 
software tool aids system administrators to anticipate, track and correct 
system performance bottlenecks and I/O problems.

    NetArchitect is a network modeling tool that utilizes a Windows-based 
graphical user interface.  This package is designed for the network 
administrator who has the responsibility of designing and installing a new 
network, or maintaining and expanding existing structures.  NetArchitect also 
has practical applications as a pre-sales tool for systems integrators, VARs 
and other channels selling or consulting on network management.

    ViewPoint is a real-time data collector of approximately 2,000 different 
system attributes.  It operates on select computer mainframes and all major 
open system server platforms.  While the data is collected on the computer 
system, ViewPoint allows the user to replay the real-time data on any 
Windows-based PC. Included in ViewPoint are extensive comparative and 
auto-analysis capabilities and an auto-correlation engine.

    MultiPoint provides the ViewPoint capabilities on distributed networks or 
local area networks (LANS).  The ProPoint product is an extension of 
ViewPoint in that it provides an extensive analytical capability to conduct 
longitudinal analysis of historic data.

    ProPoint is a capacity planning tool that maintains historical computer 
system data on a personal computer and enables a system manager to display 
graphically long term historical performance and capacity metrics which can 
be organized in notebooks and stored in Microsoft database files.  

    ControlPoint is a host independent, single point of control, application 
management system.  Using the latest client/server and Microsoft-Registered 
Trademark- Windows-TM- technology, ControlPoint controls multiple platforms 
and hosts from a single point and can be implemented in discreet modules or 
as a complete applications management solution.

MATRIDIGM CORPORATION

    Zitel has invested approximately $5,558,000 to acquire a 30% interest in 
MatriDigm Corporation ("MatriDigm"), a private company formed to provide 
COBOL maintenance and re-engineering services.  The Company's percentage 
ownership has changed and will continue to change as MatriDigm raises 
additional capital and as options under MatriDigm's stock option plan vest 
and are exercised.

    The initial focus of MatriDigm has been development of technology to 
automate the conversion of legacy software code which could not recognize or 
utilize dates after the year 1999 (the "Year 2000 Problem") into code which 
is able to recognize and utilize dates into the next century.  MatriDigm has 
devoted substantially all of its resources to development of such technology. 
In May 1997, MatriDigm announced the commercial availability of its MAP2000 
windowing process for programs written in ANSI COBOL 85.  MatriDigm intends 
to continue to refine its current tool set and to extend its tool set to 
modify other COBOL languages, as well as other computer languages widely used 
to write programs for IBM mainframe computers.


                                      12.
<PAGE>

    Substantially all software programs written assume that the first two 
digits of any date are "19" and cannot recognize or utilize dates commencing 
with the year 2000.  Estimates of the cost and available market for 
conversion of existing code to eliminate this problem are in the hundreds of 
billions of dollars.  A large number of companies, many of which have 
substantially greater resources than MatriDigm, are offering conversion 
services or are developing systems to provide such services, and competition 
is expected to be intense among the providers of such services.

    The Company's solution services division provides Year 2000 conversion 
services, including project management, planning analysis, code conversion 
and testing.  The primary code conversion methodology of this division is 
based on MatriDigm's MAP2000 process; the division will also use other tools 
and processes to meet customer needs in different environments.  The Company 
has an exclusive right to create temporary conversion centers utilizing the 
MAP2000 process at customer sites for customers with security or other 
requirements which prohibit delivery of code to offsite conversion 
facilities.  The solution services division was formed in the first quarter 
of the current fiscal year. As the commercial availability of MatriDigm's 
MAP2000 windowing process was announced in May 1997, at June 30, 1997 this 
division had not as yet realized revenue.  

MARKETING

    The Company offers its products through system integrators, value-added 
resellers and distributors, OEMs, and directly to end users.  The Company's 
direct sales and service staff consists of employees who operate from 
California, Colorado, Florida, Georgia, Kansas, Massachusetts, Maryland, New 
Jersey, New York, Virginia, Washington and Europe.

    The Company provides maintenance for its software products, but does not 
maintain a field service organization for its hardware products.  Typically, 
customers contract with a third party to maintain the Company's hardware 
products.  Technical support personnel make or assist in the initial 
installations; assist the service organization with problem resolution and 
field upgrades; and help customers determine how best to deploy Zitel 
products in their system to achieve the maximum benefit.

COMPETITION

    The Company's storage division competes with independent companies, such 
as EMC Corp and Data General Corporation, as well as manufacturers of 
computer systems, such as Unisys Corporation, Sun Microsystems, Inc. and 
Hewlett-Packard Corporation.  Most of its competitors have substantially 
greater financial resources and installed bases than the Company.  The data 
storage market is intensely competitive, with technological advances driving 
continuous erosion of prices for data storage capacity.  The Company competes 
by providing customers with superior performance solutions. 

    The market for system management tools in which the Company's software 
products division competes is intensely competitive.  Many of the companies 
with which the Company competes such as Hewlett-Packard Corporation, Computer 
Associates and BGS, Inc. have substantially larger installed bases and 
greater financial resources than the Company.  The Company competes in this 
market by providing better solutions for its customers.

    The market for Year 2000 services is intensely competitive, with services 
being provided by a number of national, regional and local firms, many of 
which have existing relationships and contractual arrangements with 
customers.  Many of these competitors have substantially greater financial, 
technical and marketing resources than the Company and MatriDigm.  The 
ability of the Company and MatriDigm to compete in this market will depend on 
the ability of MatriDigm to develop a successful automated solution.  

PATENTS

    Management believes that technical expertise, responsiveness to user 
requirements and implementation of technological advances are mandatory 
factors in the markets in which the Company competes.  The Company applied 
for additional patent protection on certain elements of its CASD products, 
VAM software products and other products 


                                      13.

in the development stage.  The Company currently holds eight issued United 
States patents.  There can be no assurance that any of the Company's patents 
provide meaningful protection.

MANUFACTURING AND SUPPLIERS

    The Company manufactures a large percentage of its hardware products from 
standard component parts and subassemblies purchased from others.  Certain of 
these parts, including printed circuit boards and subassemblies, are produced 
from design and to its specifications.  Use of such standard items simplifies 
the manufacturing process, reduces the number of items carried in inventory 
and permits the Company to expand its product line while minimizing the 
expense of designing and developing new assemblies.

    The Company utilizes various subcontractors to assemble and solder 
printed circuit boards using material purchased by the Company or to produce 
surface mount ASICs to the Company's workmanship standards.  Completed 
assemblies are then inspected by the Company's receiving inspection 
department and submitted to its manufacturing test operation.  This test 
operation provides board-level and system-level testing under stressed 
operating conditions.

    The Company's hardware products use a large number of components that are 
generally available from several sources and the Company believes that the 
loss of one or more of its suppliers will not have a material adverse effect 
on operations.

EMPLOYEES

    At July 1, 1997, the Company employed 233 persons on a full-time basis, 
77 in research and development, 19 in manufacturing, 86 in sales and 
marketing, and 61 in general management and administration.

    The Company believes that its further success will depend, in part, on 
its ability to attract and retain qualified employees, who are in great 
demand. None of the Company's employees are represented by a labor union and 
the Company believes that its employee relations are good.

PROPERTIES

    The Company leases its headquarter manufacturing and office facility in 
Fremont, California.  Under a non-cancelable operating lease, which expires 
in March 1998, with an average annual rent of $502,000.  The Company is 
presently negotiating for an extension of this lease and believes that 
suitable facilities are available at substantially increased rent.  

    The software division is headquartered in an office facility in Fairfax, 
Virginia, under a lease which expires in October 1997 with a rent of 
approximately $437,000 per annum.  The Company is negotiating for an 
extension of this lease and believes that suitable facilities are available.  
The software division also occupies leased facilities in England under leases 
expiring in 2010 with rents of approximately $124,000 per annum.

                           SELLING SECURITYHOLDERS

    The following table sets forth the names of the Selling Securityholders, 
the number of shares of Common Stock owned by each Selling Securityholder 
prior to this offering, the number of shares of Common Stock being offered 
for the account of each Selling Securityholder and the number of shares of 
Common Stock to be owned by each Selling Securityholder after completion of 
this offering. This information is based upon information provided by the 
Selling Securityholders.  Because the Selling Securityholders may offer all, 
some or none of their Common Stock, no definitive estimate as to the number 
of Shares thereof that will be held by the Selling Securityholders after such 
offering can be provided.

(1) Unless otherwise indicated below, the persons named in the table have or  
    will have sole voting and investment power with respect to all shares  
    beneficially owned by them.

(2) Assumes, arbitrarily, that the Debentures are converted at a conversion 
    price of $8.33-1/3 per share (exclusive of shares issuable upon 
    conversion of accrued 5% interest on the Debentures to the date of 
    conversion) and no limits or adjustments are applicable. Pursuant to the 
    terms of the Debentures, if the Debentures had been actually converted 
    on July 11, 1997 the conversion price would have been $17.75 (90% of the 
    average of the daily low trading price of the Common Stock for the five
    trading days immediately preceding such date) at which price the number 
    of shares owned by these Selling Securityholders would have been 
    approximately 1,408,253 shares (exclusive of shares issuable upon 
    conversion of the accrued 5% interest). Pursuant to the terms of the 
    Debentures, the Debentures are convertible by any holder only to the 
    extent that the number of shares of Common Stock thereby issuable, 
    together with the number of shares of Common Stock owned by such holder 
    and its affiliates (but not including shares of Common Stock underlying 
    unconverted Debentures) would not exceed 4.9% of the then outstanding 
    Common Stock as determined in accordance with Section 13(a) of the 
    Exchange Act. Accordingly the number of shares of Common Stock set forth 
    in the table for these Selling Securityholders exceeds the number of 
    shares of Common Stock that these Selling Securityholders could own 
    beneficially at any given time through their ownership of the Debentures. 
    In that regard, beneficial ownership of these Selling Securityholders set 
    forth in the table is not determined in accordance with Rule 13d-3 under 
    the Exchange Act.

(3) Assumes the sale of all Shares offered hereby.  The Company has agreed to 
    pay all reasonable fees and expenses incident to the filing of this 
    offering.  See "Plan of Distribution."

(4) Citadel Limited Partnership is the managing general partner of Nelson
    Partners ("Nelson") and the trading manager of Olympus Securities,
    Ltd. ("Olympus") and consequently has voting control and investment
    discretion over securities held by both Nelson and Olympus.  The
    ownership information for Nelson does not include the shares owned by
    Olympus and the ownership information for Olympus does not include the
    shares owned by Nelson.

                                 PLAN OF DISTRIBUTION

    The Shares may be offered by the Selling Securityholders or by certain 
pledgees, donees, transferees or other successors in interest from time to 
time in long or short transactions on the Nasdaq National Market System, in 
privately negotiated transactions, through the writing or exercise of 
options, or a combination of such methods of sale, at fixed prices that maybe 
changed, at market prices prevailing at the time of sale, at prices related 
to such prevailing market prices or at negotiated prices.  The Selling 
Securityholders may effect such transactions by selling the Shares directly 
or by or through agents or broker-dealers who may receive compensation in the 
form of discounts, concessions or commissions from the Selling 
Securityholders or the purchasers of the Shares for whom such broker-dealers 
may act as agent or to whom they sell as principal or both (which 
compensation to a particular broker-dealer might be in excess of customary 
commissions).

    The Selling Securityholders and any underwriters, dealers or agents that 
participate in the distribution of the Shares may be deemed to be 
"underwriters" within the meaning of the Securities Act, and any discounts, 
commissions or concessions received by them and any provided pursuant to the 
sale of the Shares by them might be deemed to be underwriting discounts and 
commissions under the Securities Act.  In order to comply with the securities 
laws of certain states, if applicable, the Shares will be sold in such 
jurisdictions only through registered or licensed brokers or dealers.  In 
addition, in certain states the Shares may not be sold unless it has been 
registered or qualified for sale in the applicable state or an exemption from 
the registration or qualification requirement is available and is complied 
with.

    Under applicable rules and regulations under the Exchange Act, any person 
engaged in the distribution of the Shares may not simultaneously engage in 
market making activities with respect to such Shares for a period of nine 
business days prior to the commencement of such distribution.  In addition 
and without limiting the foregoing, each Selling Securityholder will be 
subject to applicable provisions of the Exchange Act and the rules and 
regulations thereunder, including, without limitation, rules 10b-2, 10b-6 and 
10b-7, which may limit the timing of purchases and sales of the Shares by the 
Selling Securityholders.  All of the foregoing may affect the marketability 
of the Shares.

    The Company entered into agreements with the Selling Securityholders to 
register their Shares under applicable federal and state securities laws.  
The Company will pay substantially all of the expenses incident to the 
offering and sale of the Shares to the public, other than commissions, 
concessions and discounts of underwriters, dealers or agents.  Such expenses 
(excluding such commissions and discounts) are estimated to be $40,000.  Such 
agreements provide for cross-indemnification of the Selling Securityholders 
and the Company to the extent permitted by law, for losses, claims, damages, 
liabilities and expenses arising, under certain circumstances, out of 
registration of the Shares.

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

     The following table sets forth the expenses payable by the Company in 
connection with the sale, issuance and distribution of the securities being 
registered, other than underwriting discounts and commissions.  All amounts 
are estimates except the SEC registration fee.  None of these expenses will

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Registrant's Amended and Restated Articles of Incorporation and Bylaws 
include provisions to (i) eliminate the personal liability of its directors 
for monetary damages resulting from breaches of their fiduciary duty to the 
extent permitted by California law and (ii) require the Registrant to 
indemnify its directors and officers to the fullest extent permitted by 
California law, including circumstances in which indemnification is otherwise 
discretionary.  Pursuant to California law, a corporation generally has the 
power to indemnify its present and former directors, officers, employees and 
agents against expenses incurred by them in connection with any suit to which 
they are, or are threatened to be made, a party by reason of their serving in 
such positions so long as they acted in good faith and in a manner they 
reasonably believed to be in, or not opposed to, the best interests of a 
corporation, and, with respect to any criminal action, they had no reasonable 
cause to believe their conduct was unlawful.  The Registrant believes that 
these provisions are necessary to attract and retain qualified persons as 
directors and officers. These provisions do not eliminate liability for 
breach of the director's duty of loyalty to the Registrant or its 
stockholders, for acts or omissions not in good faith or involving 
intentional misconduct or knowing violations of law, for any transaction from 
which the director derived an improper personal benefit or for any willful or 
negligent payment of any unlawful dividend or any unlawful stock purchase 
agreement or redemption.

ITEM 17. UNDERTAKINGS.

      The undersigned registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a 
     post-effective amendment to this registration statement to include any 
     material information with respect to the plan of distribution not 
     previously disclosed in the registration statement or any material 
     change to such information in the registration statement;

(2)  That, for the purpose of determining any liability under the Securities 
     Act, each post-effective amendment that contains a form of prospectus 
     shall be deemed to be a new registration statement relating to the 
     securities offered therein, and the offering of such securities at that 
     time shall be deemed to be the initial bona fide offering thereof; and
                                           
(3)  To remove from registration by means of a post-effective amendment any 
     of the securities being registered which remain unsold at the 
     termination of the offering. The undersigned registrant hereby 
     undertakes that, for purposes of determining any liability under the 
     Securities Act of 1933, each filing of the registrant's annual report 
     pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 
     1934 (and, where applicable, each filing of an employee benefit plan's 
     annual report pursuant to Section 15(d) of the Securities Exchange Act 
     of 1934) that is incorporated by reference in the registration statement 
     shall be deemed to be a new registration statement relating to the 
     securities offered therein, and the offering of such securities at that 
     time shall be deemed to be the initial BONA FIDE offering thereof. 
     Insofar as indemnification for liabilities arising under the Securities 
     Act may be permitted to directors, officers and controlling persons of 
     the registrant pursuant to provisions described in Item 15, or 
     otherwise, the registrant has been advised that in the opinion of the 
     Securities and Exchange Commission such indemnification is against 
     public policy as expressed in the Securities Act and is, therefore, 
     unenforceable.  In the event that a claim for indemnification against 
     such liabilities (other than the payment by the registrant of expenses 
     incurred or paid by a director, officer or controlling person of the 
     registrant in the successful defense of any action, suit or proceeding) 
     is asserted by such director, officer or controlling person in 
     connection with the securities being registered, the registrant will, 
     unless in the opinion of its counsel the matter has been settled by 
     controlling precedent,submit to a court of appropriate jurisdiction the 
     question whether such indemnification by it is against public policy as 
     expressed in the Securities Act and will be governed by the final 
     adjudication of such issue.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection 
with the filing by Zitel Corporation (the "Company") of a Registration 
Statement on Form S-3 (the "Registration Statement") with the Securities and 
Exchange Commission covering the offering of 3,061,401 shares of the 
Company's Common Stock, with a par value of $0.001 of which 61,401 shares are 
currently owned by one of the Selling Securityholders (the "Shares") and up 
to 3,000,000 (the "Conversion Shares") of which are issuable upon the 
conversion of the Company's outstanding 5% Convertible Subordinated 
Debentures (the "Debentures").

In connection with this opinion, we have examined the Registration Statement, 
the Company's Certificate of Incorporation and Amended and Restated Bylaws, 
and such other documents, records, certificates, memoranda and other 
instruments as we deem necessary as a basis for this opinion.  We have 
assumed the genuineness and authenticity of all documents submitted to us as 
originals, the conformity to originals of all documents submitted to us as 
copies thereof, and the due execution and delivery of all documents where due 
execution and delivery are a prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion 
that the Common Shares are validly issued, fully paid, and nonassessable and 
that Conversion Shares, when issued upon conversion of the Debentures in 
accordance with the terms thereof, will be validly issued, fully paid and 
nonassessable.

We consent to the filing of this opinion as an exhibit to the Registration 
Statement and to the reference to our firm under the caption "Legal Matters" 
in the Prospectus included in the Registration Statement.

Very truly yours,

Cooley Godward LLP


/s/ John L. Cardoza
