                    Notes to Condensed Financial Statements

1.   In the opinion of management, the accompanying financial statements
present fairly the financial position, results of operations and cash flows for
the periods shown.  The second quarter results for each year represent 13 weeks
of operations ended Friday, September 29, 1995 and September 30, 1994.  The
financial data included herein was compiled in accordance with the same
accounting policies applied to the Company's audited annual financial
statements.  Any adjustments made were of a normal recurring nature.

     The results of operations for the six month period ended September 29,
1995 are not necessarily indicative of the results  expected for the full year.


2. A summary of long-term debt follows:

</TABLE>


On August 31, 1995, BIS Partners, L.P. (BIS) agreed to cancel $450,000 of
long-term debt and to reduce the interest rate on the remaining debt to 8
percent.  In addition, the repayment terms were modified to interest-only
through March 31, 1996, with repayment in 36 equal installments thereafter.
In accordance with this agreement, the Company reduced the amount of debt owed
to BIS to equal the total cash to be repaid to BIS for both principal and
interest.  This resulted in a second quarter extraordinary gain of $282,000.
All future payments to BIS will be recorded as a reduction in the debt balance.
In connection with this transaction, the Company issued warrants to BIS to
purchase 450,000 shares of its capital stock at $1.9375 per share (the fair
market value at issue date), exercisable through August 31, 2005.

Item 2.   Management's Discussion and Analysis of Financial Condition and
Results of Operations

Financial Condition
-------------------
The Company experienced a net decrease in cash of $135,000 for the first six
months of fiscal 1996.  Cash used for investing activities (additions to
equipment and software production costs) and financing activities exceeded the
cash provided by operating activities of $114,000.  The positive cash from
operations was realized from depreciation and amortization, lower levels of
inventories and receivables and increased customer advances and unearned
revenues.  These amounts were sufficient to offset the loss before
extraordinary item and reductions in accounts payable and other accrued
expenses.  This result also compared very favorably to a decrease of $764,000
in cash for the first six months of the prior year.

The Company plans to meet its cash requirements for fiscal 1996 by continuing
to generate positive cash flow from operating activities.  The Company has
earned a profit before extraordinary item in four out of the last five quarters
and believes it is properly positioned to achieve growth in Javelan sales which
have high profit margins.  In addition, the Company plans to minimize
investments in new assets and debt repayment during 1996.  While
the Company  plans to incur an increase in capitalized software, it also
expects a further decrease in the net amount of equipment and leasehold
improvements and a reduction in the level of inventories.  BIS Partners, L.P.
agreed to cancel $450,000 of its debt in August, 1995, to receive interest-only
payments on its debt during fiscal 1996, and to provide a $500,000 line of
credit through June 30, 1996.  There has been no borrowing under this line of
credit.  Finally, the Company believes that additional financing sources will
become available as its operational performance improves.


Results of Operations
---------------------
For the quarter ended September 29, 1995, total revenues decreased 13.2% from
the same quarter in 1994, with a net loss before extraordinary item of $177,000
compared to a net profit of $35,000 in the second quarter of the prior year.
For the six month period ended September 29, 1995, total revenues decreased
10.8% compared with the six months ended September 30, 1994.  The six month net
loss before extraordinary item was $173,000 compared to a net loss of $230,000
incurred in the comparable period for the prior year.  After taking the
extraordinary item into account, a net profit of $105,000 was incurred in the
second quarter of the current year and a net profit of $109,000 was incurred
for the first six months.  The principal reason for the loss before
extraordinary item incurred in the second quarter was lower services revenues
at the same time an increase in services expenses was incurred.

                                      -8-

Product sales decreased 41.4% for the comparable second quarter, and 47.7% for
the comparable first six months.  This was primarily due to a de-emphasis of
the sale of low margin commodity products.  However, an increase was realized
in the sale of Javelan, the Company's windows-based management software
product which has only a small associated cost of sales.  As a result, margins
on product sales improved from 23.6% to 42.1% for the comparable second quarter
and from 20.8% to 49.9% for the comparable six month period.

Services revenues decreased 8.1% for the comparable second quarter and 2.5% for
the comparable six month periods.  These decreases were principally the result
of decreased revenues from hardware time and material billings and software
maintenance contracts.  In addition, two large hardware maintenance contracts
did not renew effective August 1, 1995 based on customer decisions to do self
maintenance.  This was the primary reason for the drop in services revenues
from the first to the second quarter of this fiscal year.  The Company is
actively pursuing new contracts to replace those that did not renew.  Margins
on services revenues decreased for the comparable second quarters and six month
periods as the cost of providing services increased by 1.3% and 0.6%,
respectively.  Savings in labor costs have been offset by increased costs for
parts utilized to maintain equipment.

The Company experienced a small decrease in the amount of selling, general and
administrative expenses it incurred in the comparable second quarters and first
six month periods.  However, due to lower levels of revenues, these expenses
increased from 16.7% to 18.7% of total revenue for the comparable quarters and
from 17.5% to 19.0% for the comparable six month periods.  Expenditures for
product development and engineering, before taking into account amounts
capitalized and amortized for software production costs, were approximately the
same for the comparable periods.

Interest expense increased from 1.6% to 1.7% of total revenues for the
comparable second quarters and from 1.4% to 1.9% for the comparable six month
periods.  These increases were the result of lower levels of revenues and
higher interest rates.

The $282,000 of extraordinary gain recorded in the second quarter resulted from
an agreement with BIS Partners, L.P. (BIS) to cancel $450,000 of its debt with
the Company.  The gain was computed by reducing the amount of debt recorded on
the Company's books to an amount equal to the total cash to be repaid to BIS
for both principal and interest.  As a result, all future payments on the
current notes outstanding to BIS will be recorded as a reduction in the debt
balance with no interest expense being recognized.  This had a favorable impact
on interest expense in the second quarter and will continue to have a favorable
impact in future quarters.

No income taxes were recognized in the statements of operations since the
Company has use of net operating loss carryforwards to offset any taxes.

A loss of $.03 per share was incurred in the first six months of this year
compared to a loss of $.04 per share in the first six months of last year.  The
extraordinary gain amounted to $.05 per share resulting in net income of $.02
per share for the first six months of this year.  The increase in the weighted
average number of common shares outstanding for the comparable periods resulted
primarily from the issuance of 2,030,000 common shares upon the conversion of
the Company's Series D preferred stock which was not included in the number of
shares until the second quarter of last year.
