One of my childhood computers was a Tandy 2000. This was a 186-based PC-incompatible computer available from Radio Shack. It was more performant than an AT, could access more base memory (due to a disk-based rather than ROM BIOS), and available at a lower price so it was a real contender before it was clear that the IBM standard would be used by everybody.

Not only could it run Windows 1.0, Microsoft used the Tandy 2000 internally for Windows development because in the early 1980s it was the only x86 machine out there that could do hi-res (640x400) color graphics. So, getting Windows 2.x backported to the 2000 is definitely feasible.

I used some (pirated) software that included a bundled Windows 2 runtime on an Amstrad PC1512 with CGA (but enhanced to 16 colors in 640x200 to make GEM look good in the sales brochures) in the late 80s. The Windows app ran in mono 640x200.

This unlocked some memories.

I wish I'd been able to "acquire" one of the ACT Apricots that my dad's old work had. They were "portable" in the sense they had a handle very firmly attached, and I think the keyboard (which had a little strip of hotkeys with an LCD screen above - waaay ahead of you, Apple) clipped into the bottom of the unit.

The Apricot F1 was another cool one, about the size of a shoebox with a trackball rather than a mouse - when no-one else had any kind of pointing device!
