        In connection with the filing by Pioneer-Standard Electronics, Inc., an
Ohio corporation (the "Company"), with the Securities and Exchange Commission
under the provisions of the Securities Act of 1933, as amended, of a
Registration Statement on Form S-3 with respect to up to $200,000,000 of the
Company's common shares, without par value (the "Common Shares"), and its debt
securities (the "Debt Securities") (hereinafter collectively referred to as the
"Securities"), to be sold by the Company from time to time, we have examined
the following:

        (i)     the Amended Articles of Incorporation, as amended, 
                and the Amended Code of Regulations of the Company,
                each as currently in effect;

        (ii)    the form of Registration Statement on Form S-3
                (including Exhibits thereto) referred to above and to be
                filed with the Securities and Exchange Commission
                (the "Registration Statement");

        (iii)   the proposed form of Underwriting Agreement
                pursuant to which the Securities are to be
                purchased by the Underwriters and resold to the
                public;

        (iv)    the proposed form of Indenture under which the Debt
                Securities are to be issued; and

        (v)     such other documents as we deemed it necessary to
                examine as a basis for the opinions hereinafter
                expressed.

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

        (i)     The Company is incorporated and validly existing 
                under the laws of the State of Ohio;
