Standard Logic, an Anaheim electronics manufacturer, said that it has begun negotiations to acquire Euless Aero Components, a precision machining firm near Dallas. Details of the Standard Logic offer were not disclosed. Dennis A. Wade, Standard Logic president, said that terms of the deal “are still pretty fluid” but added that he expects a definitive agreement shortly and that details will be available then. Euless Aero had revenues of $5.75 million and net income of $338,000 for the fiscal year ending November, 1987. Standard Logic, which reported a loss for its fiscal 1987, said it has posted a profit of about $63,000 on $1.8 million in sales for the first nine months of fiscal 1988. Standard Logic manufactures proprietary printed circuit boards and uses them to build prototype computers for clients.
