               proceeding (excluding traffic violations or similar

Item 3.  Source and Amount of Funds

As of the date hereof, the Reporting Entities may, in the aggregate, be deemed

Shares were purchased in the open market by BCP and BlueLine Catalyst VIII with
their investment capital.


                                  Page 5 of 10

Item 4.  Purpose of the Transaction

The purchases by BCP and BlueLine Catalyst VIII of the Shares were effected
because the Reporting Entities believe that the Company represents an attractive
investment based on the Company's operating history and continuing business
prospects. When BCP and BlueLine Catalyst VIII began purchasing Common Stock,
the Company's stock price was $5.50 and the Reporting Entities believed it
possible for the Common Stock to rise to a level twice that amount within twelve
to eighteen months. Subsequent events at the Company have caused the Reporting
Entities to raise that target price higher.

BlueLine Partners and its affiliated investment entities, including BCP and
BlueLine Catalyst VIII, seek to make investments in companies deemed by them to
be undervalued relative to their potential and in situations where they believe
BlueLine's efforts can help to create or unlock value. In the case of the
Company, the Reporting Entities believed it essential for the Company to
transition away from its traditional technology-centric orientation and toward a
greater customer and market orientation. This transition was likely to require
certain changes in management. On July 5, 2005, the Company made substantial
progress in this direction with the hire of Mr. Barry Caldwell to be the
Company's Chief Executive Officer. The Reporting Entities believe that Mr.
Caldwell will use the Company's large cash position to expand the Company's
business while better articulating the Company's potential beyond that as a
technology pioneer.

As part of their investment strategy, the Reporting Entities hope to have the
opportunity to discuss and work with management on various initiatives designed
to improve the Company's prospects and performance. Areas of focus will include
marketing, customer communications and investor relations, additional executive
hires, international expansion and strategic transactions.

Depending on market conditions, general economic conditions and other factors,
the Reporting Entities may purchase additional shares of Common Stock in the
open market or in private transactions, or may dispose of all or a portion of
the shares of Common Stock that they or any of them presently own or may
hereafter acquire.

Item 5.  Interest in Securities of the Issuer

(a)  As of the date of this Schedule 13D, each of the Reporting Entities may be
     deemed to own 394,666 shares of Common Stock. These shares represent
     approximately 5.3% of the shares of Common Stock outstanding based on
     7,513,130 shares of the Company's Common Stock outstanding as reported in
     the Company's Form 10-Q for the Company's fiscal quarter ended July 2, 2005
     as filed with the Securities and Exchange Commission on August 16, 2005.

     The Reporting Entities are making this single, joint filing because they
     may be deemed to constitute a "group" within the meaning of Section
     13(d)(3) of the Act. Each Reporting Entity expressly disclaims beneficial
     ownership of any of the shares of Common Stock other than those reported
     herein as being owned by it.


                                  Page 6 of 10

(b)  As of the date of this Schedule 13D: (i) BCP beneficially owns 231,246
     shares of Common Stock with which BCP has shared voting power and shared
     dispositive power with the other Reporting Entities; (ii) BlueLine Catalyst
     VIII beneficially owns 163,420 shares of Common Stock with which BlueLine
     Catalyst VIII has shared voting power and shared dispositive power with the
     other Reporting Entities; and (iii) BlueLine Partners beneficially owns
     394,666 shares of Common Stock with which BlueLine Partners has shared
     voting power and shared dispositive power with the other Reporting
     Entities.

(c)  Information concerning transactions in the Common Stock effected by the
     Reporting Entities during the past sixty days is set forth in Exhibit B
     hereto and is incorporated by this reference. All of the transactions set
     forth in Exhibit B were open market transactions for cash.

(d)  No person (other than the Reporting Entities) is known to have the right to
     receive or the power to direct the receipt of dividends from, or the
     proceeds from the sale of, the Shares.

(e)  Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer

Pursuant to Rule 13d-1(k) promulgated under the Act, the Reporting Entities have
entered into an agreement with respect to the joint filing of this statement,
and any amendment or amendments hereto, which is attached hereto as Exhibit A.
