NonLinear Systems was an electronics test tool builder
in Solana Beach, CA ('bout half an hour north of San Diego). I don't recall when
it was formed by Andrew Kay (probably the 50's or even earlier), but it created the
first digital voltmeter in the early 60's. It was a very inventive company.
NLS *almost* made minicomputers in the early 1960s. They offered some
very large digital ATE systems that had simple processors made out of
small logic boards.
