wow what a great thread, weird that its like in parallel to my fun experiments on a PS/2 model 60.
Ive been slowly working on some article on why OS/2 was always doomed to fail, and I lay the blame squarely on the Model 60. On the one hand, it was FAR too expensive, weighing in at a near $6,000 for the new machine. At the same time it's incapable of running OS/2, mostly as the motherboard maxes at 1MB of RAM, and requires RAM expansion boards (thankfully the 60 has plenty of slots) but the fact you have to expand your system, paradoxically means the PS/2 model 60 was also too cheap.
Many people point to the AT (5170) as to some IBM promise, but the PS/2 line was created in an utter panic in 1986 reacting to the coming clone 386 machines, and a quick 1 year knee jerk reaction to losing the PC battle. Launched too early in 1987 with no next gen software the PS/2 model 60 should never have existed. And heck the Model 80 was grossly overpriced, but at least a 32bit machine.
Sigh there is so much to go on, but you've seemed to found a lot of it. There is a fair bit more to go as well, vintage books & magazines help a lot as well, and of course don't forget to check out Windows/286 & Windows/386.

Windows/286 can multitask very well behaved tiny MS-DOS programs in a window. As you can (hopefully) see a gwbasic programming running, adding a number, while Zork1 runs in the foreground. Very limited by RAM, but still neat!
Windows/386 of course is the mind blowing v86 technology with hard v86 machines! It's great!
