     This Post-Effective Amendment No. 1 relates to the Registration Statement
on Form S-3 (File No. 333-64705), as amended by that Amendment No. 1 (the
"Registration Statement"), of Colorado MEDtech, Inc. (the "Company") pertaining
to 3,781,756 shares of the Company's common stock, no par value per share
("Common Stock"), which was filed with the Securities and Exchange Commission
and became effective on September 29, 1998 and was amended on November 3, 1998.
The Registration Statement registered (i) 3,500,000 shares of Common Stock for
sale by selling shareholders of the Company who acquired the shares pursuant to
purchases in private transactions and (ii) 281,756 shares of Common Stock for
sale by selling shareholders of the Company who acquired the shares pursuant to
non-qualified stock options. The Company, CIVCO Holding, Inc. ("Holding") and
CMT Mergerco, Inc. ("Mergerco"), a wholly-owned subsidiary of Holding, entered
into an Agreement and Plan of Merger (the "Merger Agreement"), dated as of March
12, 2003, as amended on May 20, 2003, pursuant to which Mergerco merged with and
into the Company, with the Company surviving as a wholly-owned subsidiary of
Holding (the "Merger"). The Merger became effective on July 18, 2003 upon filing
of the Certificate of Merger with the Secretary of State of the State of
Colorado.

     As a result of the Merger, the offering pursuant to the Registration
Statement has been terminated. In accordance with an undertaking made by the
Company in the Registration Statement to remove from registration, by means of a
post-effective amendment, any of the securities which remain unsold at the
termination of the offering, the Company hereby removes from registration the
securities of the Company registered but unsold under the Registration
Statement.
