Item 1.

(a) The name of issuer as to whose securities this statement relates is
Ace Comm Corp. (the "Issuer").
(b) The address of Issuer's principal place of business is 209 Perry

Item 2.
- -------
(a-c) This statement is being filed by Amerindo Investment Advisors Inc., a
California corporation whose principal executive offices are located at One
Embarcadero Center, Suite 2300, San Francisco, California, 94111 ("Amerindo"),
Amerindo Investment Advisors, Inc., a Panama corporation, whose principal
executive offices are located at Edificio Sucre, Calle 48 Este, Bella Vista,
Apartado 6277, Panama 5, Panama ("Amerindo Panama"), the Amerindo Advisors (UK)
Limited Retirement Benefits Scheme, whose address is 43 Grovesner Street,
London WIX 9PG England (the "Retirement Benefits Scheme"), Alberto W. Vilar,
Gary A. Tanaka, James P.F. Stableford and Renata Le Port (sometimes hereinafter
collectively referred to as the "Reporting Persons"). Although this statement
is being made jointly by the Reporting Persons, each of them expressly
disaffirms membership in any group under Rule 13d-5 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise. Amerindo
and Amerindo Panama are sometimes hereinafter collectively referred to as the
"Advisor Entities."
Each of the Advisor Entities is an investment advisor, and all of the
subject securities have been purchased by the Advisor Entities (or, in the case
of securities held, by the Retirement Benefits Scheme) in the ordinary course
of their respective businesses as investment advisors and not with the purpose
of effecting change or influencing the control of the issuer or in connection
with or as a participant in any transaction having such purpose or effect,
including any transaction subject to Rule 13d-3(b) under the Exchange Act.
Amerindo is registered as an investment advisor under the Investment Advisors
Act of 1940, as amended. Messrs. Vilar and Tanaka are the sole shareholders
and directors of each of the Advisor Entities. Messrs. Alberto W. Vilar, Gary
A. Tanaka, James P.F. Stableford and Ms. Renata Le Port are joint trustees of
the Retirement Benefits Scheme (which is a qualified employee benefit plan).
Because each of the Advisor Entities is obligated to act in the best interests
of its respective clients and in accordance with the respective mandates of
those clients, and because the trustees of the Retirement Benefits Scheme are
required to act in the best interest of the beneficiaries thereof, there is no
agreement between or among any of the Reporting Persons to act together with
respect to the issuer or its securities, except that they may, from time to
time and provided that transactions are otherwise being effected at the same
time, aggregate orders for client accounts in order to receive more favorable
trading terms.
(d-e) This statement is being filed as to the Common Stock of
Ace Comm Corp., Cusip Number 004404109.

(h) This statement is being filed jointly by the Reporting Persons,
although each of them expressly disaffirms membership in any group under Rule
13d-5 under the Exchange Act.
Item 4. Ownership.
- ------ ---------
(a-c) The following table sets forth for each of the Advisor Entities and
for the Plan the aggregate number of shares of the Common Stock of the Issuer
beneficially owned by such person as of December 31, 1997, and the percentage
which such shares constitute of the total number of shares outstanding, as
reflected on the Issuer's Form 10Q for the Quarter ended September 30, 1997
(with beneficial ownership determined as set forth in Rule 13d-3 under the
Exchange Act, but with beneficial ownership being expressly disclaimed). Messrs.
Vilar and Tanaka, as the sole shareholders and directors of the Advisor
Entities, share with each other investment and dispositive power as to all
of the shares shown as owned by the Advisor Entities, who otherwise have sole
investment and dispositive power with respect thereto, except that each client
of the Advisor Entities has the unilateral right to terminate the advisory
agreement with the Advisor Entity in question on notice which typically need
not exceed 30 days. Messrs. Alberto W. Vilar, Gary A. Tanaka, James P.F.
Stableford and Ms. Renata Le Port are joint trustees of the Retirement Benefits
Scheme.
