I have to say that the Atari OS, floating point rom, and basic were all
really great and very good to learn from. They published all the source
with comments and none of it was from MS! Later when I worked with MS
basic, I was horrified for a number of reasons.

DEC Rainbow, definitely, I had one at GE Lighting. Of course we had all
kinds of goodies there. Core memory, bubble memory, etc.
How about the Epson desktop computers? (The name escapes me at the
moment.) The OS and all apps, including a full-featured word processor,
were written in Forth. It had a very nice green mono display and cool
features, but could be slow at times.
The first IBM clone that was 'close' that I worked with was the Columbia
PC. We also had the first Kaypros and Compaq's (the real, original
Compaq's, unless I have my companies confused). The system in a fat,
heavy suitcase with the built-in 4" mono display.

Probably. I have an early NCR computer like that.
I did most of my embedded development at GE with a Compupro-Godbout MP/M
8/16. We did most 'networking' with serial cables switched with a
Develcon system. I could sit at either the MP/M or an early PC and
connect to the switch with a terminal program and then connect to the
VAX 11/780, 11/750, the Perkin-Elmer running Unix Ver. 7 and later
SystemV.2, or even dialout from the modem pool. This was in 1984.
