Thats linux. Not UNIX. I think tool suites from companies now dead made tiny-c and the like, and had tractably small memory model, split i+d stuff in the c compiler toolchain. Not much work on them. Why not?
Well.. targeting 8086, 80286 was somehow off the radar for a bunch of people. I think because a lot of flight ready milspec stuff ran on 6502 or 6800, and especially the latter was a classic gordon-moore model simple register==memory model, a lot more ports went into 6800(x)
Interesting to think if IBM had selected a motorola CPU like this instead of an Intel, or if Intel had been in a mood to adopt a PDP11 instruction set... what the world would be like.
As a DEC-10 and PDP11 and Vax person, I used CP/M, it was ok. I could survive. MS-DOS blind-sided me. I had no idea what was coming down the pipe. talk about walking into a room of razors with closed eyes.
