But still, I am curious. 386 PS/2s were expensive.
My first job had a Model 70-A21 as a demo box:

First 3.5" hard disk I ever saw. Blazing speed for 1988. A 25MHZ 386! With secondary cache!
This thing was $10,500 for the base spec, if I remember rightly -- it's over 35 years ago -- and that excluded a keyboard, monitor and DOS.
In my 2nd year in that job I bought a 2nd hand Acorn Archimedes A310. 8MHz ARM 2, 1MB RAM, 20MB hard disk.
It was considerably quicker than that IBM. Like 4-8x the speed. And it was £800 used. With a screen, keyboard and RISC OS!
Probably £1500 new, so about one tenth of the price of a comparably-specified Model 70.
My point being... as someone said upthread, they didn't know anyone with a private Mac home computer. Yeah, well, a 386 PS/2 was even more expensive than a Mac.
