                                                   April 28, 1994





Pioneer-Standard Electronics, Inc.
4800 East 131st Street
Cleveland, Ohio 44105

                 We are familiar with the proceedings taken and proposed to be
taken by Pioneer-Standard Electronics, Inc., an Ohio corporation (the
"Company"), with respect to an additional 500,000 Common Shares, without par
value  (the "Shares"), of the Company to be offered and sold from time to time
pursuant to the Company's 1991 Stock Option Plan (the "Plan").  As counsel for
the Company, we have assisted in the preparation of a Registration Statement on
Form S-8 (the "Registration Statement") to be filed by the Company with the
Securities and Exchange Commission to effect the registration of the Shares
under the Securities Act of 1933, as amended.

                 In this connection, we have examined the Articles of
Incorporation and the Code of Regulations of the Company, both as amended,
records of proceedings of the Board of Directors and Shareholders of the
Company relating to the Plan, and such other records and documents as we have
deemed necessary or advisable to render the opinion contained herein.  Based
upon our examination and inquiries, we are of the opinion that the Shares, when
offered and sold upon the exercise of the options pursuant to the terms and
conditions of the Plan, will be duly authorized and validly issued, fully paid
and nonassessable.

                 We hereby consent to the filing of this opinion as Exhibit 5.1
to the Registration Statement.

                                                   Very truly yours,



                                                   CALFEE, HALTER & GRISWOLD
