       Re:  Securities and Exchange Commission
            Registration Statement on Form S-8   
            ----------------------------------

Gentlemen:

       As counsel to Comcast Corporation, a Pennsylvania corporation (the
"Company"), we have assisted in the preparation for filing with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "1933 Act"), of a registration statement on Form S-8 (the
"Registration Statement") for the purpose of registering under the 1933 Act
20,000,000 shares of the Company's Class A Special Common Stock, $1.00 par
value (the "Shares"), which may be issued pursuant to the Comcast Corporation
1996 Stock Option Plan (the "Plan").  In connection therewith, we have examined
the Company's Articles of Incorporation and By-laws, each as amended, the Plan
and such minutes and other documents as we have deemed appropriate.  We have
also examined such provisions of law and made such other inquiries as we have
deemed necessary or appropriate for purposes of the opinion expressed herein.

  Based upon the foregoing, we are of the opinion that the 20,000,000 Shares
are duly and validly authorized, and, when issued to the holders of options
granted pursuant to and in accordance with the terms of the Plan, will be duly
and validly issued, fully paid and non-assessable.

       We hereby expressly consent to the filing of this opinion with the
Commission as an exhibit to the Registration Statement.  In giving this
consent, we do not thereby admit that we are in the category of persons whose
consent is required under Section 7 of the 1933 Act or the rules and
regulations of the Commission thereunder.

                                Very truly yours,

                                /s/  WOLF, BLOCK, SCHORR AND 
                                     SOLIS-COHEN
