                                  THE COMPANY

GENERAL

   Interphase Corporation ("Interphase" or the "Company") designs, develops, 
manufactures, markets and supports high performance networking and mass 
storage products based on advanced  technologies for some of today's most 
powerful computer systems.  Interphase's networking and mass storage products 
include high performance network adapters, network operating system software 
drivers, Fiber Distributed Data Interface ("FDDI") concentrators, and mass 
storage controllers.  The Company's networking products implement high speed 
networking technologies such as FDDI, Asynchronous Transfer Mode ("ATM") and 
fast ethernet (both 100VG-AnyLAN and 100 Base T), as well as the older, more 
established ethernet (10 Base T) and Token Ring technologies, that facilitate 
the high speed movement of information across computer networks.  The 
Company's mass storage controllers are currently based on Small Computer 
Systems Interface ("SCSI") technology and in early 1996 will include products 
based upon the emerging high speed Fibre Channel technology to facilitate the 
movement of data to and from mass storage devices.   Fibre Channel can also 
be used for a high speed interconnect in clustered applications.  The 
Company's products are designed to not only comply with the appropriate open 
system technical standards but also optimize  the performance of the 
customers networking and mass  storage environments.

     The Company's networking adapters and mass storage controllers consist 
of both hardware and software.  The hardware is essentially printed circuit 
boards which plug into the backplane of a computer and incorporate industry 
standard bus architectures of the most popular client/server platforms such 
as VMEbus, Sbus, EISA, NIO, GIO, Micro Channel Architecture and the emerging 
industry standard PCI bus, as well as input-output front-ends for many 
performance oriented computer systems.   The Company's networking adapters 
support a variety of media including fiber optic cabling and unshielded 
twisted pair ("UTP") and shielded twisted pair ("STP") copper wiring.   The 
Company's software consists of drivers for the most popular client/server 
operating systems such as Windows NT, Netware, HP-UX, IRIX, O/S2, Solaris, 
SunO/S, AIX and certain real-time operating systems.  In addition, the 
software may include diagnostics, station management ("SMT") and in certain 
cases may off-load the processing of the protocol stack from the server to 
the adapter card.  The Company's FDDI concentrator products are stand-alone 
networking devices which serve as a single point of connection for multiport 
local area networks as well as perform certain network traffic management 
tasks.  The mass storage controllers provide a high-speed connection to 
computer peripheral devices, such as disk drives, tape drives and printers.  
The Company's products are used in a wide range of computer applications 
including graphics workstations, high performance work groups, CPU clusters, 
medical imaging, telephone switching, on-line transaction processing and 
financial services networks.

     With respect to the client/server computer market, the majority of the 
Company's products have been installed in the server (or "Host") as opposed 
to the client (or "desktop").  This reflects the Company's historical focus 
on the development of high-performance, fully featured products that are 
targeted for the most demanding computer networks.  Given the recent 
emergence of more powerful desktop computing environments and a growth in 
demand for data intensive applications, the Company believes that its 
strengths in certain networking and mass storage technologies will create 
significantly  more opportunities for desktop installations of its products 
in future years.

     The Company believes that its success in gaining significant market 
share in its selected markets is dependent upon not only the development and 
manufacture of high performance, high quality products but also in 
establishing and maintaining the appropriate distribution channels.   The 
Company has original equipment manufacturer ("OEM") agreements with some of 
the best known companies in  the computer business for its networking 
products and mass storage controllers.  The Company's customers include OEM's 
of computer systems and networking switches, systems integrators, value added 
resellers  ("VAR"), distributors and end-users.  The Company believes that it 
must maintain an ongoing synergistic relationship with its customers and 
demonstrate technology leadership coupled with sophisticated manufacturing 
and customer  support capabilities.  The Company's manufacturing and 
development activities are certified under the ISO 9001 international quality 
standard.   The Company's headquarters and manufacturing facilities are 
located at its Dallas, Texas location.

     The Company, a Texas corporation, was founded in 1977, completed its 
initial public offering in 1984 and a secondary public offering in 1991.

RECENT DEVELOPMENTS

DEVELOPMENT FOCUS ON ATM PRODUCTS.  During fiscal 1995 and to date, 
Interphase has applied the majority of its engineering development resources 
to products for the emerging ATM market.  This networking technology provides 
for enhanced quality of service in the integration of voice, video and data 
transmission in local area networks and wide area networks, significant 
improvements in network manageability, and scalability of speed from 25 mega 
bits per second ("Mbps") to 51, 100, 155 and 622 Mbps.   This focus has 
resulted in a number of accomplishments by the Company including: the 
introduction of over 25 ATM network interface cards during 1995, its PCI ATM 
adapter card being selected as one of three finalists for Best of Show at the 
Spring 1995 Networld/Interop show, the announcement of the industry's lowest 
priced ATM card in February 1995, and the joint announcement with Bay 
Networks of the first complete, standards based, open ATM solution in 
December 1994.  In addition, during fiscal 1995, the Company has continued to 
introduce new FDDI products, including PCI, GIO and Sbus FDDI adapters and 
the M400 low cost four or eight port FDDI concentrator with copper or fiber 
connectivity and optional SNMP management.  The Company also introduced the 
industry's first Sbus 100VG-AnyLAN adapter and is developing the Company's 
first Fibre Channel mass storage controller for introduction in 1996.

DISTRIBUTION CHANNELS.  During 1995, the Company has been successful in 
establishing new alliances with key computer and networking switch OEM's for 
its ATM products, including Bay Networks, UB Networks, NEC, Agile Networks, 
and Hewlett Packard.   In addition, the Company has entered into distribution 
agreements with key national and international distribution partners, 
including Anixter, Fuji-Xerox, Gates/Arrow and Westcon.

BOARD OF DIRECTORS.  On September 20, 1995, James F. Halpin, president and 
chief executive officer of CompUSA Inc., was elected to the Company's Board 
of Directors.   Mr. Halpin's election represents an addition to the Board of 
Directors, bringing the total number of Board members to eight.

                                RISK FACTORS

    Prospective purchasers of the shares of Common Stock offered hereby 
should consider the following factors:

QUARTERLY FLUCTUATIONS

    The Company's quarterly financial results may vary significantly 
depending upon factors such as capital spending levels of customers, general 
economic conditions, the timing of significant orders and the timing and 
success of new product introductions by the Company and its competitors.  
Factors such as quarterly variations in financial results could cause the 
market price of the Common Stock to fluctuate substantially.

    The majority of the Company's revenues currently consist of sales of FDDI 
network interface and SCSI controller cards to computer OEM customers.   
These products typically produce gross margins of 50% or more.   The Company 
anticipates that sales of its newer technology products to the larger desktop 
markets will be at lower margins.  Changes in the mix of products sold and 
the mix of distribution channels through which the Company's products are 
sold may cause additional fluctuations in the Company's overall gross margins 
and operating margins.  The Company's expense levels are based, in part, on 
its expectations as to future revenues and, as a result, net income would be 
disproportionately affected by a reduction in revenue.  In  response  to 
competitive pressures or new product introductions by competitors, the 
Company may take certain pricing or marketing actions that could materially 
and adversely affect the Company's operating results.

    There can be no assurance that future sales will result in gross and 
operating margins in line with past performance or current expectations.  In 
addition, due to the potential quarterly fluctuation in operating results, 
the Company believes that quarter-to-quarter comparisons of its results of 
operations are not necessarily meaningful and should not be relied upon as 
indicators of future performance.

NEW PRODUCT DEVELOPMENT

    The  markets for the Company's products are characterized by  rapid 
technological development, evolving industry standards, frequent new product 
introductions and relatively short product life cycles.   The Company's 
success is substantially dependant upon its ability to anticipate and react 
to these changes, maintain its technological expertise, expand and enhance 
its product offerings in existing technologies, and to develop in a timely 
manner new products in emerging technologies, such as ATM-based networking, 
which achieve market acceptance.  The Company believes it must offer products 
to the market which not only meet ever-increasing performance and quality 
standards, but  also  provide compatibility and interoperability with 
products  and architectures offered by various vendors, including workstation 
and personal computing architectures and computer and networking systems.   
There can be no assurance that the Company will be able to address 
effectively the performance, compatibility and interoperability issues raised 
by technological changes or new industry standards.  The Company's business, 
results of operations and financial condition would be materially adversely 
affected if the Company were to incur significant  delays or be unsuccessful 
in developing  new  products  or enhancements, or if any such products or 
enhancements did not gain market acceptance.   In addition, there can be no 
assurance that products or technologies developed by others will not render 
the Company's products obsolete.

DEPENDENCE ON KEY PERSONNEL

     The Company's success to date has been significantly dependent on the 
contributions of a number of its key technical and management employees.  The 
Company does not maintain life insurance policies on its key employees and, 
except with a few executive officers, does not have employment agreements 
with key employees.  The loss of the services of one or more of these key 
employees could have a material adverse effect on the Company.  In addition, 
the Company believes that its future success will depend in large part upon 
its ability to attract and retain 


                                      5

<PAGE>

highly-skilled and motivated technical, managerial, sales and marketing 
personnel.   Competition for such personnel is intense.  There can be no 
assurance that the Company will be successful in attracting and retaining the 
personnel that it requires.

DEPENDENCE ON SUPPLIERS

     The Company uses sole-sourced custom integrated circuits on most of its 
products as well as standard off-the-shelf items presently available from two 
or more  suppliers.    Although recent experience with respect  to  parts 
availability has been generally favorable, the past may not be an accurate 
indicator of the future since there is no assurance that shortages will not 
occur.   Should shortages occur, the Company's revenue levels would likely be 
adversely affected and, potentially, relationships with customers could be 
impaired.

DISTRIBUTION RISKS

     The Company's sales are made through OEMs, VARs, distributors and system 
integrators.  The Company selects its OEMs, VARs, distributors and system 
integrators based on a subjective evaluation of a combination of factors, 
including potential sales volume, visibility, anticipated financial 
stability, expertise in the networking industry, potential distribution 
channel conflicts, and geographic scope.  There can be no assurance that the 
resellers selected by the Company will in the future perform favorably with 
respect to such factors and, to the extent that they do not, the adverse 
effect on the Company could be material.  The Company's VAR, distributor and 
systems integrator customers generally offer products of several different 
companies, including products which are competitive with the Company's 
products.   Accordingly, there is a risk that these resellers may give higher 
priority to products of other suppliers, thus reducing their efforts to sell 
the Company's products.

     During 1995, the Company has entered into ATM product distribution 
agreements with several major national and international distributors.  While 
the Company believes these channels will be key to its strategy of expanding 
its sales of networking products from being primarily server computer 
oriented to include the desktop computer market, there can be no assurance 
that the Company will be successful in establishing and maintaining an 
effective distribution system.

     Because the Company does not sell products directly to end users, it is 
difficult to ascertain current demand for existing products or anticipated 
demand for newly introduced or future products.

     At present the Company's customer base is somewhat concentrated and 
there is no assurance that its customer base will not become more 
concentrated.   Six of the Company's OEM customers accounted for 
approximately 50% of the Company's sales during fiscal 1995, including one 
customer which accounted for 15%.  In the past, the Company has experienced 
fluctuations in the volume of activity with individual OEM customers and 
distributors as well as changes in its OEM customer and distributor base, and 
it expects such fluctuations and changes to continue in the future.  
Accordingly, there can be no assurance that the Company's principal customers 
will continue to purchase products from the Company at current levels.  
Moreover, the Company typically does not enter into long-term volume purchase 
contracts with its customers, and the Company's customers have certain rights 
to extend or delay the shipment of their orders.  The loss of one or more of 
the Company's major customers, the reduction, delay or cancellation of orders 
or a delay in shipment of the Company's products to such customers could 
materially and adversely affect the Company's business, operating results and 
financial condition.

COMPETITION

     The computer networking industry is intensely competitive and is 
significantly affected  by  product  introductions and market activities  of  
industry participants.  The Company expects substantial competition to 
continue.   The Company's competitors include vendors specifically dedicated 
to the mass storage adapter and computer network product markets.   While the 
Company's major OEM customers have traditionally chosen not to manufacture 
controllers for their products or do not manufacture sufficient quantities or 
types of controllers to meet 


                                     6

<PAGE>


their needs, there can be no assurance that these customers will continue to 
meet part or all of their needs through out-sourcing.   Increased competition 
could result in price reductions, reduced margins and loss of market share, 
all of which would materially and adversely affect the Company's business, 
operating results and financial condition.

     Many of the Company's current and potential competitors have 
significantly greater financial, technical, marketing and other resources and 
larger installed bases than the Company.  Several of the Company's 
competitors have been acquired by major networking companies.   These 
acquisitions are likely to permit the Company's competitors to devote 
significantly greater resources  to  the development and marketing of new 
competitive products and the marketing of existing competitive products to 
their larger installed bases.  The Company expects that competition will 
increase substantially as a result of these and other industry consolidations 
and alliances, as well as the emergence of new competitors.  There can be no 
assurance that the Company will be able to compete successfully with its 
existing or new competitors or that competitive pressures faced by the 
Company will not materially and adversely affect its business, operating 
results and financial condition.

INTELLECTUAL PROPERTY

     While the Company believes that its success is ultimately dependent upon 
the innovative skills of its personnel and its ability to anticipate 
technological changes, its ability to compete successfully will depend, in 
part, upon its ability to protect proprietary technology contained in its 
products.  The Company currently relies upon a combination of trade secret, 
copyright and trademark laws and contractual restrictions to establish and 
protect proprietary rights in its products.  There can be no assurance that 
these statutory and contractual arrangements will prove sufficient to deter 
misappropriation of the Company's technologies or independent third-party 
development of  similar technologies.  The  development of alternative,  
proprietary  and  other technologies by third parties could have a material 
adverse effect on the competitiveness of the Company's products.  Further, 
the laws of some countries do not provide the same degree of protection of 
the Company's proprietary information as do the laws of the United States.  
Finally, the Company's adherence to industry-wide technical standards and 
specifications may limit the Company's opportunities to provide proprietary 
product features capable of protection.

     The Company is also subject to the risk of litigation alleging 
infringement of third party intellectual property rights.  There can be no 
assurance that third parties will not assert infringement claims against the 
Company in the future with respect to current or future products.   Any such 
claims could require the Company to expend significant time and money in 
litigation, pay damages, develop non-infringing technology or acquire 
licenses to the technology which is the subject of asserted infringement.

EFFECT OF SALES UNDER THIS PROSPECTUS

     The Shares being sold pursuant to this Prospectus constitute 
approximately 18% of the outstanding shares of Common Stock of the Company.  
The Company cannot predict the timing of the sales of such Shares or the 
effect that the sales of such Shares will have on the market price prevailing 
from time to time.

                               USE OF PROCEEDS

   The Company will not receive any proceeds from the sale of the Common 
Stock offered hereby.

                            PLAN OF DISTRIBUTION

     It is anticipated that the Selling Shareholder may sell Shares in open 
market or block transactions or otherwise in the over-the-counter market, or 
in private transactions, at prices related to prevailing market prices or at 
negotiated prices.  The Selling Shareholder may effect such transactions by 
selling shares to or through broker-dealers, and such broker-dealers may 
receive compensation in  the form of discounts, concessions or commissions 
from the Selling Shareholder or the purchasers of shares for whom such 
broker-dealers may act as agent or to whom they may sell as principal or 
both.  In addition to sales of Shares pursuant to this Prospectus, any Shares 
that qualify for sale pursuant to Rule 144 under the Securities Act may be 
sold under Rule 144 rather than pursuant to this Prospectus.

     Upon any sale of the Shares offered hereby, the Selling Shareholder and 
participating  broker-dealers or selling agents may  be  deemed  to  be 
"underwriters" as that term is defined in the Securities Act, in which event 
any discounts, concessions or commissions received by them, which are not 
expected to exceed those customary in the types of transactions involved, or 
any profit on resales of the Shares by them, may be deemed to be underwriting 
commissions or discounts under the Securities Act.  To the extent required, 
the specific Shares to be sold, purchase price, public offering price, the 
names of any such broker-dealer or selling agent and any applicable 
commission or discount with respect to a particular offer will be set forth 
in an accompanying Prospectus Supplement.

     In order to comply with the securities laws of certain states, if 
applicable, the Shares may be sold in such jurisdictions only through 
registered or licensed brokers or dealers.  In addition, Shares may not be 
sold unless they have been registered or qualified for sale or an exemption 
from registration  or qualification requirements is available and is complied 
with under applicable state securities laws.

    The Company and the Selling Shareholder have agreed, and hereafter may 
further agree, to indemnify each other and certain other persons, including 
broker-dealers, against certain liabilities in connection with any offering 
of the Common Stock, including liabilities arising under the Securities Act.

                             SELLING SHAREHOLDER

     Michael E. Cope is a founder, a director and former Chief Executive 
Officer of the Company.  As of March 1, 1996 he beneficially owned 873,900 
shares (including 122,500 shares issuable upon exercise of options), 
constituting 18% of the outstanding shares of Common Stock of the Company.  
17,500 shares which may be acquired by Mr. Cope upon the exercise of certain 
non-qualified options are not being registered hereunder.   All of the Shares 
being offered hereby are being offered by Mr. Cope.   He has sole ultimate 
voting and investment power with respect to the shares owned by him.

                                LEGAL MATTERS

     The validity of the Common Stock offered hereby is being passed upon for 
the Company  and the Selling Shareholder by Gardere & Wynne, L.L.P.,  3000 
Thanksgiving Tower, Dallas, Texas.  David H. Segrest, a partner of Gardere & 
Wynne, L.L.P., is a director of the Company and beneficially owned 54,400 
shares of Common Stock as of March 1, 1996.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article 2.02-1 of the Texas Business Corporation Act provides for 
indemnification of directors and officers in certain circumstances.  In 
addition, the Texas Miscellaneous Corporation Laws Act provides that a 
corporation may amend its Articles of Incorporation to provide that no 
director shall be liable to the Registrant or its shareholders for monetary 
damages for any act or omission in the director's capacity as such, provided 
that the liability of a director is not eliminated or limited (i) for any 
breach of the director's duty of loyalty to the Registrant or its 
shareholders, (ii) for acts or omissions not in good faith that constitute a 
breach of the director's duty to the Registrant or acts or omissions which 
involve intentional misconduct or a knowing violation of law, (iii) any 
transaction from which such director received an improper personal benefit or 
(iv) any act or omission for which the liability of the director is expressly 
provided for by an applicable statute. Article XIII of the Registrant's 
Articles of Incorporation contains the foregoing amendment.

     Article VII of the Registrant's bylaws provides, in general, that the 
Registrant may indemnify its directors and officers to the fullest extent 
permitted by Texas law.

     An insurance policy obtained by the Registrant provides for indemnification
of officers and directors of the Registrant and certain other persons against 
liabilities and expenses incurred by any of them in certain stated proceedings 
and under certain stated conditions.

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:

          (i)     To include any prospectus required by section 10(a)(3) of 
the Securities Act of 1933;

           (ii)      To  reflect in the prospectus any facts or events  
arising after the effective date of the registration statement (or the most 
recent post-effective amendment thereof) which, individually or in the 
aggregate, represent a fundamental change in the information set forth in the 
registration statement;

          (iii)     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;

           PROVIDED, HOWEVER, that the undertakings set forth in paragraphs 
(i) and (ii) above do not apply if the information required to be included in 
a post-effective amendment by those paragraphs is contained in periodic 
reports filed by the Registrant pursuant to section 13 or section 15(d) of 
the Securities Exchange Act of 1934 that are incorporated by reference in 
this registration statement.

      (2)   That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment 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.

      (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.

      (4)   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 section 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 


                                     II-2


<PAGE>


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.

      (5)   Insofar as indemnification for liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers and 
controlling persons of the  Registrant pursuant to the foregoing provisions, 
or otherwise, the Registrant has been informed that in the opinion of the 
Securities and Exchange Commission such indemnification is against public 
policy as expressed in the 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 Act and will be governed by the final 
adjudication of such issue.

      (6)   For purposes of determining any liability under the Securities 
Act of 1933, the information omitted from the form of prospectus filed as 
part of this Registration Statement in reliance upon Rule 430A and contained 
in a form of prospectus filed by the Company pursuant to Rule 424(b)(1) or 
(4) or 497(h) under the Securities Act shall be deemed to be part of this 
Registration Statement as of the time it was declared effective.

      (7)   For the purpose of determining any liability under the Securities 
Act of 1933, 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.

Interphase Corporation
13800 Senlac
Dallas, Texas  75234

Gentlemen:

     We have acted as counsel for Interphase Corporation, a Texas corporation
(the "Company"), in connection with the Registration Statement on Form S-3 (the
"Registration Statement") to be filed with the Securities and Exchange
Commission on or about April 2, 1996 in connection with the registration under
the Securities Act of 1933, as amended, of (i) 751,400  shares (the "Selling
Shareholder Shares") of Common Stock, no par value ("Common Stock"), of the
Company to be sold by Michael E. Cope (the "Selling Shareholder"), (ii) 30,000
shares (the "30,000 Shares") of Common Stock issuable to the Selling Shareholder
upon exercise of that certain Interphase Corporation Nonqualified Stock Option
Agreement, dated June 21, 1994 (the "30,000-Share Option Agreement"), and (iii)
75,000 shares (the "75,000 Shares") of Common Stock issuable to the Selling
Shareholder upon exercise of that certain Interphase Corporation Nonqualified
Stock Option Agreement, dated June 21, 1994 (the "75,000-Share Option
Agreement").

     With respect to the foregoing, we have examined such documents and
questions of law as we have deemed necessary to render the opinions expressed
below.  Based upon the foregoing, we are of the opinion that:

     1.   The Selling Shareholder Shares are duly and validly issued, fully paid
and nonassessable.

     2.   The 30,000 Shares issuable upon exercise of the 30,000-Share Option
Agreement are duly and validly authorized and reserved for issuance upon such
exercise and, when issued upon such exercise in accordance with the terms of the
30,000-Share Option Agreement, will be duly and validly issued, fully paid and
nonassessable.

     3.   The 75,000 Shares issuable upon exercise of the 75,000-Share Option
Agreement are duly and validly authorized and reserved for issuance upon such
exercise and, when issued upon such exercise in accordance with the terms of the
75,000-Share Option Agreement, will be duly and validly issued, fully paid and
nonassessable.

     We consent to the use of this opinion as Exhibit 5.1 to the Registration
Statement and to the use of our name in the Registration Statement under the
heading "Legal Matters."

                                       Very truly yours,
