Dear Mr.Meyerhoff:

      We have reviewed your filing and have the following
comments.
We have limited our review of your filing to those issues we have
addressed in our comments.  Where indicated, we think you should
revise your document in future filings in response to these
comments.
If you disagree, we will consider your explanation as to why our
comment is inapplicable or a revision is unnecessary.  Please be
as
detailed as necessary in your explanation.  In some of our
comments,
we may ask you to provide us with information so we may better
understand your disclosure.  After reviewing this information, we
may
raise additional comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or on any other
aspect
of our review.  Feel free to call us at the telephone numbers
listed
at the end of this letter.





Form 10-K for the period ending December 25, 2004

Managements Discussion and Analysis, page 15

Fiscal Years Ended December 25, 2004 and December 27, 2003, page
20

1. We see that you have elected to present stock based
compensation
expense as a separate line item on the face of the income
statement.
If material in future filings, please expand your discussions of
the
various expense categories to also discuss variances in line items
inclusive of related stock compensation charges.  Also, the
selective
financial data and quarterly information should include the
allocation as well.

2. We note the significant inventory and inventory reserve
balances
at December 25, 2004.  Please discuss these balances and the
related
turnover rates on a comparative basis and the reasons for the
significant increase in the reserve for excess and obsolete
inventory
in the current year.  Also, explain the basis of your conclusions
regarding the recoverability of inventory as of the most recent
balance sheet date.  Revise future filings to clarify.


Consolidated Balance Sheets, page 52

3. We see from disclosures at Note 3 that approximately $112.2
million of your marketable securities at December 25, 2004 mature
after one year.  Please tell us why these amounts are not
classified
as non-current assets in your balance sheet.  Revise future
filings
to correctly classify your marketable securities as either current
or
non-current.  Refer to paragraph 17 of FAS 115.

Note 12. Related Party Transactions, page 76

4. Significant related party transactions should be disclosed on
the
face of the financial statements, pursuant to Rule 4-08(k) of
Regulation S-X.  Revise future filings to disclose separately the
transactions with related parties or advise us why this disclosure
is
not necessary.





      As appropriate, please respond to these comments within 10
business days or tell us when you will provide us with a response.
Please furnish a cover letter with your response that keys your
responses to our comments and provides any requested information.
Detailed cover letters greatly facilitate our review.  Please file

additional comments after reviewing your responses to our
comments.

adequacy of the disclosure in the filing to be certain that the

Exchange Act of 1934 and that they have provided all information
investors require for an informed investment decision.  Since the

to
a company`s disclosure, they are responsible for the accuracy and
adequacy of the disclosures they have made.

provide,
in writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of the
disclosure in the filings;

proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

      In addition, please be advised that the Division of
