In the early '70s we had a contract to build the controllers for the ALS 
system. The heart of the controller was an Eagle Signal electromechanical 
stepping switch which was pretty much obsolete. The harnesses had to be 
laced since the FAA wasn't sure about those new-fangled nylon cable ties.

One project I worked on used TI's TMS9900 microprocessor of TI-99/4 fame. 
Or notoriety, take your pick. Its claim to fame was TI produced rad-hard 
parts. TI had ties to the defense industry that made them a natural.

TI was also involved with the 'expert systems' flavor of AI after neural 
networks fell on their face in the '80s.
