ITEM 5.   OTHER EVENTS.

Acquisition of Edge Semiconductor Incorporated
- ----------------------------------------------

          The Registrant issued a press release on September 22, 1997,
announcing that it had entered into a letter of intent to acquire Edge
Semiconductor Incorporated ("Edge").  Edge is a fabless semiconductor company
which designs, markets and supplies analog and mixed-signal integrated circuits
specifically optimized for automated test equipment.  The acquisition of Edge
provides the Registrant with additional design capabilities and an opportunity
to fulfill the growing demand for analog semiconductors in new market
applications.

          On October 2, 1997, the Registrant entered into, and consummated, an
Agreement and Plan of Merger (the "Merger Agreement") among the Registrant, ESI
Acquisition Corp., a wholly-owned subsidiary of the Registrant, and Edge.
Pursuant to the Merger Agreement, the Registrant issued 749,977 shares of Common
Stock, $.01 par value (the "Merger Shares"), to all the shareholders of Edge and
all the holders of options and warrants to purchase shares of common stock of
Edge.  A total of 37,500 of the Merger Shares are being held in a one year
escrow (the "Escrow Shares") as security for the indemnification obligations of
Edge's former shareholders pursuant to the Merger Agreement.  The transaction
was structured as a reverse triangular merger and qualified for treatment as a
pooling of interests.  As a result of the tax free reorganization, Edge now is a
wholly-owned subsidiary of the Registrant.  The completion of the acquisition of
Edge was announced in a press release issued by the Registrant on October 3,
1997.

          Pursuant to the Merger Agreement, the Registrant agreed to register
the resale of the Merger Shares (including the Escrow Shares) under the
Securities Act of 1933, as amended.  On October 10, 1997, the Registrant filed
its Registration Statement on Form S-3, Registration No. 333-37699 (the
"Registration Statement") with the Securities and Exchange Commission (the
"Commission").  The Registration Statement was declared effective by the
Commission on October 23, 1997.  Affiliates of Edge (to whom 527,909 of the
Merger Shares were issued) have agreed not to sell any of their Merger Shares
until the Registrant's release of its earnings for its quarter ending November
2, 1997, in order to comply with the pooling requirements.  That earnings
report is currently contemplated to be issued on or about November 18, 1997.
The proceeds from the sale of any Escrow Shares will continue to be held in
escrow for the duration of the one year escrow period.

     Substantially the same information contained herein has been previously
reported in the Registration Statement. Copies of the Merger Agreement and the
two press releases issued by the Registrant are appended as exhibits to this
Report.
