It's always surprising how much variety there was in the mini market of that
era.
Even when you take out what might be called the 2nd tier of manufacturers such
as Microdata, Prime and so on, there was still a plethora of also-rans.
I find it an interesting era: once ICs were readily available and easy to
design with (mainly TTL), everyone and their dog decided they would take a stab
at building and marketing a CPU. I was a kid in that era so wasn't on the
inside, but my offhand interpretation is that while some of them may have been
successful in niche areas such as instrumentation, in the main they got shook
out when the reality of maintaining, marketing and evolving a system
architecture hit. But, that's an historical progression common to many/most new
technologies -
same thing happened in the microprocessor market a few years a later.
A Varian has been sitting on ebay for sometime now .. sitting, because the
price is silly:
