ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

Forward Looking Statements
--------------------------

     This Quarterly Report contains forward-looking statements within the
meaning of the Private Securities Reform Act of 1995, particularly statements
regarding market opportunities, customer acceptance of products, gross margin
and marketing expenses. These forward-looking statements involve risks and
uncertainties, and the cautionary statements set forth below, identify important
factors that could cause actual results to differ materially from those in any
such forward-looking statements. Such factors include, but are not limited to,
adverse changes in general economic conditions, including changes in the
specific markets for the Company's products, product availability, decreased or
lack of growth in the electronics industry, adverse changes in customer order
patterns, increased competition, lack of acceptance of new products, pricing
pressures, lack of success in technological advancements, risks associated with
foreign operations and other factors.

RESULTS OF OPERATIONS

Net Sales
---------

     Net sales for the three months ended June 30, 1999, were $3,288,000
compared to $4,890,000 for the same period in the prior year. Machine sales were
negatively affected by the continuing soft demand in the electronics industry
and particularly in the PC memory assembly sector. Sales of manufacturing
services grew by 19% over the same three months in the prior year. Increased
orders from the existing account base along with several new customers fueled
the manufacturing services sales growth.

Gross Profit
------------

     Gross profit declined as a percentage of sales due to a higher mix of
manufacturing services sales, which generated a negative gross profit in the
current quarter compared to much smaller negative gross profit in the
comparative quarter last year. The manufacturing services division gross profit
decreased from the prior quarter primarily due to a lower portion of consignment
(labor only) orders compared to turnkey (labor and material) orders. Profit
margins on consignment orders are generally higher than on turnkey orders. The
machine division gross profit was negatively impacted by additions to reserves
for obsolescence related to the PlaceMaster(R) machine inventory. In addition,
the gross profit continued to be affected by excess capacity in the machine
manufacturing division.

Sales, General and Administrative
---------------------------------

     Selling and marketing expenses declined in the current quarter primarily
due to cost-saving reductions in headcount and lower commission expenses
resulting from the decline in sales.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
     RESULTS OF OPERATIONS, CONTINUED

Research and development
------------------------

     Research and development expenses in the current quarter were incurred to
complete the Company's new automatic label placer machine. Three machines have
been released to field beta test and production has begun on the first lot.

                         LIQUIDITY AND CAPITAL RESOURCES

     The Company used cash of $126,000 in operating activities for the six
months ended June 30, 1999. Accounts receivable decreased primarily due to the
lower sales level. Demonstration equipment fluctuates as machines are routinely
sold and replaced. Accessories are transferred in and out of demonstration
equipment based on the specific demonstration requirements. Expenditures in the
current quarter for property and equipment were $164,000, and primarily
consisted of equipment for the final stage of the manufacturing services
division facility expansion. The Company's line of credit with its' bank matured
on March 31, 1999. The Company's bank has declined to renew the line based on
the recent operating results. Currently, the Company has no plans to seek a line
of credit with another bank. The Company believes that cash provided from
operations, and cash balances at June 30, 1999 will be adequate to support its
operating and investing requirements through 1999.

YEAR 2000 ISSUES

     The Year 2000 problem concerns the inability of certain computer systems to
appropriately recognize the year 2000 when the last two digits of the year are
entered in the date field. The Company has assessed its Year 2000 requirements
and believes that its major computer systems, its products, and capital
equipment are Year 2000 compliant. Therefore, the Company believes that its
costs to become Year 2000 compliant have not been material and are anticipated
to not be material in the future.

     The Company, however, could be adversely affected by the Year 2000 problem
if computer systems of third parties such as customers, suppliers, banks,
utilities, and others with which the Company does business fail to address the
Year 2000 problem successfully. While the Company continues to gather data on
the Year 2000 compliance status of its customers and suppliers, there can be no
assurance that the Year 2000 problem, if experienced by such third parties, will
not have a material adverse effect upon the Company's business, operating
results or financial condition. Of the key suppliers identified, Tenryu
Technics, the manufacturer of the private label line, has confirmed that their
Tenyru built machines are Year 2000 compliant and their assessment of general
Year 2000 readiness has been completed. The Company has not developed a
contingency plan for a worst case Year 2000 scenario. As a result of widespread
or extended failure of systems of third parties to be Year 2000 compliant, this
could have a material adverse effect on the Company's business and financial
condition or operating results.

     The above Year 2000 disclosure constitutes a "Year 2000 Readiness
Disclosure" as defined in The Year 2000 Information and Readiness Disclosure Act
(the "Act"), which was signed into law on October 19, 1998. The Act provides
added protection from liability for certain public and private statements
concerning a company's Year 2000 readiness.
