It seems to be "industrial strength" - I'm sure these were priced above the affordability threshold for most hobbyists...
Glenn, suffice it for me to say, as a digital engineer from the 1970's, that while Multibus systems when new, were not cheap; in the era, early digital computing technology (microprocessor or minicomputer), wasn't cheap either. And in due course, Multibus and other industrial-bus microcomputers, became "hobbyist"; and are hobbyist today, notwithstanding some legacy industrial uses still going on. But just because some 1970's computers were industrial, doesn't mean they didn't have a "hobby" impact or had early hobby activity. Just as college students "hacked" on expensive computers at their colleges, so did engineers and techs do the same at the time - either at work or when these systems became surplus. And today, there's a number of people "hobbying" on Multibus computers; and other such systems too. Certainly so, on the minicomputers preceding the microprocessor-based "boxes". I think to someone born after say 1995, all these "rows of boards in ugly boxes" look the same - S-100, Multibus, VMEbus, STDbus, SS-50, OSI, DEC, etc. So it disappoints me, when I see any of them referenced as "non-hobby" for one reason or another, past or present. It's my era to defend. Regards, Herb Johnson -- Herbert R.
