Ladies and Gentlemen:

     We are acting as counsel to Pinnacle Data Systems, Inc., an Ohio
corporation (the "Company"), in connection with its Registration Statement on
Form SB-2 (the "Registration Statement") filed by the Company with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
to register 50,000 common shares, without par value, of the Company (the "Common
Shares") issuable upon exercise of outstanding warrants originally issued to
Corna Securities, Inc. on April 23, 1996 (the "Warrants").

     In connection therewith, we have examined the Company's Amended and
Restated Articles of Incorporation, as amended, the Company's Amended and
Restated Code of Regulations, as amended, the records, as exhibited to us, of
the corporate proceedings of the Company, a certificate of the Secretary of the
Company, the Warrants, and such other documents and records as we considered
necessary for purposes of this opinion.  In rendering this opinion, we have
assumed the genuineness, without independent investigation, of all signatures on
all documents examined by us, the conformity to original documents of all
documents submitted to us as certified or facsimile copies and the authenticity
of all such documents.

     Based on the foregoing, we are of the opinion that:

          (1)  The Company is a corporation validly existing under the laws of
     the State of Ohio; and

          (2)  The Common Shares have been duly authorized and, when sold and
     paid for in the manner contemplated by the Registration Statement, will
     have been validly issued and will be fully paid and nonassessable.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to us under the caption "Legal Matters" in the
Prospectus which is part of the Registration Statement.

                                                  Very truly yours,

                                                  /s/ Baker & Hostetler LLP

                                                  BAKER & HOSTETLER, LLP
