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 March 31, 1999, were $4,619,000
compared to $5,306,000 for the same period in the prior year. Machine sales were
negatively affected by soft demand in the electronics industry and particularly
in the memory module assembly sector. Sales of manufacturing services grew by
12% over the same three months in the prior year. The manufacturing services
sales growth was primarily from the existing account base.

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 break-even in the comparative quarter last year. 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 reductions in headcount and lower commission expenses resulting from the
decline in sales.


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

     Research and development expenses increased in the current quarter due to
efforts to complete the Company's new assembly machine, which utilizes an
emerging technology in the circuit board assembly process.

                               AMISTAR CORPORATION

LIQUIDITY AND CAPITAL RESOURCES

     The Company used cash of $539,000 in operating activities for the three
months ended March 31, 1999. Accounts receivable increased primarily due to
delays in customer acceptance of assembly machines pending completion of certain
field upgrades. Inventory decreased due to liquidation of older machine models,
sales of thru-hole technology machines, and reductions in manufacturing services
division materials on hand. 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 $75,000, and
primarily consisted of equipment for the manufacturing services division
facility expansion. The Company's line of credit with its' bank matured March
31, 1999. The Company is in the process of renewing the line of credit and
believes the renewal will occur in the second quarter of 1999. The Company
believes that cash provided from operations, cash balances at March 31, 1999,
and available drawings from its line of credit, when renewed, 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. The Company expects to have completed gathering
data on its key customers and suppliers by June 30, 1999. 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 that they
are currently evaluating their enterprise information system for Year 2000
compliance.

     The company has not yet 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.
