Ladies and Gentlemen:

Reference is made to the Registration Statement on Form S-8 that
you intend to file with the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended, for the
purpose of registering:

     400,000 shares of Common Stock, $.01 par value (the
     "Shares") of Developed Technology Resource, Inc., a
     Minnesota corporation (the "Company"), initially issuable
     upon the exercise of stock options granted pursuant to the
     Developed Technology Resource, Inc. 1992 Stock Plan (the
     "1992 Plan"), as amended; and

     85,000 shares of common stock initially issuable upon the
     exercise of stock options granted pursuant to the Developed
     Technology Resource, Inc. 1997 Outside Directors Stock
     Option Plan (the "1997 Plan"), as amended.

We have examined such documents and have reviewed such questions
of law as we have considered necessary and appropriate for the
purposes of the opinion set forth below.

In rendering our opinion set forth below, we have assumed the
authenticity of all documents submitted to us as originals, the
genuineness of all signatures and the conformity to authentic
originals of all documents submitted to us as copies.  We have
also assumed the legal capacity for all purposes relevant hereto
of all natural persons and, with respect to all parties to
agreements or instruments relevant hereto other than the Company,
that such parties had the requisite power and authority
(corporate or otherwise) to execute, deliver and perform such
agreements or instruments, that such agreements or instruments
have been duly authorized by all requisite action (corporate or
otherwise), executed and delivered by such parties and that such
agreements or instruments are the valid, binding and enforceable
obligations of such Parties.  As to questions of fact material to
our opinions, we have relied upon certificates of officers of the
Company and of public officials.

Based on the foregoing, we are of the opinion that the Shares
have been duly authorized and, upon issuance, delivery and
payment therefor in accordance with the terms of either the 1992
Plan or the 1997 Plan, will be validly issued, fully paid and
nonassessable.

Our opinion expressed above is limited to the business
corporation laws of the State of Minnesota.

We hereby consent to the filing of this opinion as an exhibit to
the Registration Statement.

                              Very truly yours,

                              /s/ Hinshaw & Culbertson
