Between 1986 and 1988, I worked on a whole slew of
HP3000s, from the
Series III to the Series 70. They were popular in the business environment,
especially in COBOL shops. Where did they end up? You can find loads of
DEC equipment on Ebay, even IBM System 34, 36 and AS/400s, the occasional
HP1000, but the only HP3000 I recall seeing in recent years was a single
Model 37.
You answered your own question.
DEC made loads of minis (PDP and VAX).
IBM made loads of minis (S/34 and S/36).
IBM made extra sized loads of AS/400 minis (more than any other minicomputer).
HP did not make loads of 3000s.
I think it is a simple population thing.
