It’s a bit mixed, by 1990 most UNIX vendors were moving to various RISC architectures so a 68k based workstation would appear rather old fashioned for that market. People paid Serious money for a UNIX system to do Serious work, so why cheap out on yesterdays technology?
A/UX didn’t seem to do that well in the market either.
My uni had these, as I mentioned in a reply elsewhere on the thread. I'm curious to know what kind of Serious Work people here saw back in the day.
I was a student so I had relatively rare access to the high end stuff... Most of my time was spent in cheap-ish sun terminals. Later on, as a last year student, I became cooler and got access to the RISC 6000s and started hanging out with the graduate students.
Most of the Serious Work I saw was email. There was some limited running of simulations and research software from other universities, but little that required a lot of processor power on an ongoing basis. I think these were generally more useful due to their native networking capabilities and software availability than their raw CPU power. In a sense, you had to have them because everybody else had one.
