SCHEDULE 13G - TO BE INCLUDED IN STATEMENTS
FILED PURSUANT TO RULE 13d-1(b) or 13d-2(b)


	Pursuant to instructions in Item 7 of Schedule 13G, this Exhibit has 
been prepared  to identify Fidelity International Limited, Pembroke Hall, 
42 Crow Lane, Hamilton, Bermuda, a Bermudian joint stock company 
incorporated for an unlimited duration by private act of the Bermuda 
Legislature (FIL) and an investment adviser to various investment companies 
(the "International Funds") and certain institutional investors, as the 
beneficial owner of 10,000 shares or 0.02% of the common stock outstanding 
of Conner Peripherals Incorporated owned by FASST.

	Prior to June 30, 1980, FIL was a majority-owned subsidiary of 
Fidelity Management & Research Company (Fidelity), a wholly-owned 
subsidiary of FMR Corp.  On that date, the shares of FIL held by Fidelity 
were distributed, as a dividend,  to the shareholders of FMR Corp.  FIL 
currently operates as an entity independent of FMR Corp. and Fidelity.  The 
International Funds and FIL's other clients, with the exception of Fidelity 
and an affiliated company of Fidelity, are non-U.S. entities.

	A partnership controlled by Edward C. Johnson 3d and members of his 
family owns shares of FIL voting stock with the right to cast approximately 
48.879% of the total votes which may be cast by all holders of FIL voting 
stock.  Mr. Johnson 3d is Chairman of FMR Corp. and FIL.  FMR Corp. and FIL 
are separate and independent corporate entities.  FMR Corp. and FIL are 
managed independently and their Boards of Directors are generally composed 
of different individuals.  Their investment decisions are made 
independently, and their clients are different organizations.

	FMR Corp. and FIL are of the view that they are not acting as a 
"group" for purposes of Section 13(d) under the Securities Exchange Act of 
1934 (the "1934" Act) and that they are not otherwise required to attribute 
to each other the "beneficial ownership" of securities "beneficially owned" 
by the other corporation within the meaning of Rule 13d-3 promulgated under 
the 1934 Act.  Therefore, they are of the view that the shares held by the 
other corporation need not be aggregated for purposes of Section 13(d). 
However, FMR Corp. is making this filing on a voluntary basis as if all of 
the shares are beneficially owned by FMR Corp. and FIL on a joint basis.

	FIL may continue to have the International Funds or other accounts 
purchase shares subject to a number of factors, including, among others, 
the availability of shares for sale at what FIL considers to be reasonable 
prices and other investment opportunities that may be available to the 
International Funds.

	FIL intends to review continuously the equity position of the 
International Funds and other accounts in the Company.  Depending upon its 
future evaluations of the business and prospects of the Company and upon 
other developments, including, but not limited to, general economic and 
business conditions and money market and stock market conditions, FIL may 
determine to cease making additional purchases of shares or to increase or 
decrease the equity interest in the Company by acquiring additional shares, 
or by disposing of all or a portion of the shares.

	FIL does not have a present plan or proposal which relates to or would 
result in (i) an extraordinary corporate transaction, such as a merger, 
reorganization, liquidation, or sale or transfer of a material amount of 
assets involving the Company or any of its subsidiaries, (ii) any change in 
the Company's present Board of Directors or management, (iii) any material 
changes in the Company's present capitalization or dividend policy or any 
other material change in the Company's business or corporate structure, 
(iv) any change in the Company's charter or by-laws, or (v) the Company's 
common stock becoming eligible for termination of its registration pursuant 
to Section 12(g)(4) of the 1934 Act.

	  FIL, FMR Corp., through its control of Fidelity, and FASST each has 
sole power to vote and to dispose of the 10,000 shares held by FASST.
