Item 1.  Security and Issuer.

     This statement constitutes Amendment No. 6 ("Amendment No. 6") to the
Statement on Schedule 13D (the "Schedule 13D") filed with the Securities and
Exchange Commission by Barry R. Steinberg (the "Reporting Person") in connection
with the ownership of shares of Common Stock, $.01 par value (the "Common
Stock"), of Manchester Technologies, Inc., a New York corporation (the
"Company"). The principal executive offices of the Company are located at 50
Marcus Boulevard, Hauppauge, NY 11788.

     In accordance with Exchange Act Rule 13d-2, this Amendment No. 6 amends and
supplements only information that has materially changed since the December 24,
1998 filing by the Reporting Person of the Amendment No. 5 to Schedule 13D.
Unless otherwise indicated herein, terms used but not otherwise defined in this
Amendment No. 6 shall have the same respective meanings herein as are ascribed
to such terms in the Merger Agreement (as such term is defined below).

Item 4.  Purpose of Transaction.

     The following Item 4 of Schedule 13D is hereby amended and supplemented by
adding the following:

     This Amendment No. 6 relates to a voting agreement (the "Voting Agreement")
entered into by the Reporting Person and Electrograph Holdings, Inc., a Delaware
Corporation ("Parent") in connection with the execution of an Agreement and Plan
of Merger (the "Merger Agreement") among the Company, Parent and CICE
Acquisition Corp., Inc., a New York corporation ("Merger Sub") providing for a
business combination whereby (i) Parent formed Merger Sub, (ii) Merger Sub will
merge into the Company (the "Merger") with the Company as the surviving
corporation, and (iii) the Company will become a wholly-owned subsidiary of
Parent.

     At the Effective Time, the Company shareholders will be entitled to receive
in exchange for each share of Common Stock $6.40 in cash without interest.

     Pursuant to the Voting Agreement, the Reporting Person has agreed to vote
the shares of Company Common Stock beneficially owned by the Reporting Person
(the "Covered Shares") in favor of the adoption of the Merger Agreement. In
addition, the Reporting Person has agreed to vote against any action, proposal
or agreement that would (i) compete with, impede, interfere with, adversely
affect, tend to discourage or inhibit the adoption of the Merger Agreement or
the timely consummation of the transactions contemplated by the Merger
Agreement, and (ii) result in any breach of a representation, warranty, covenant
or agreement of the Company under the Merger Agreement. Notwithstanding the
foregoing, nothing in the Voting Agreement shall govern, limit or restrict the
Reporting Person's ability to exercise his fiduciary duties to the shareholders
of the Company as provided by the Merger Agreement or under applicable Legal
Requirements.

     The Reporting Person has also agreed that he will not, (a) sell, assign,
give, tender, offer, exchange or otherwise transfer any of his Covered Shares;
(b) encumber, pledge, hypothecate or otherwise permit (including by omission)
the creation or imposition of any Encumbrance on any

                                  SCHEDULE 13D
CUSIP No. 562398 10 7                                               Page 4 of 5

of his Covered Shares; or (c) enter into any Contract with respect to any of the
foregoing, in each case without the prior written consent of Parent.

     The Voting Agreement terminates upon the earlier of (a) the Effective Time
or (b) the day on which the Merger Agreement is terminated in accordance with
its terms and, if applicable, the Termination Fee is paid by the Company to
Parent pursuant to Section 8.3 of the Merger Agreement.

     The descriptions of the Merger Agreement and Voting Agreement contained in
this Amendment No. 6 are qualified in their entirety by reference to such
agreements, copies of which are included as Exhibit 1 and Exhibit 2 to this
Amendment No. 6, respectively, and are incorporated by reference herein.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
        Securities of the Issuer

     Item 6 of Schedule 13D is hereby amended and supplemented to include the
following:

     The matters set forth in Item 4 above are incorporated in this Item 6 by
reference as if fully set forth herein.

Item 7.  Material to be Filed as Exhibits

     Item 7 of the Schedule 13D is hereby amended and supplemented to include
the following:

     1. Agreement and Plan of Merger, dated as of April 17, 2005, by and among
