(It didn't have per-process memory protection, though, but it was a huge point of pride for Amiga users back in the early 90s)
- cr0sh 10y agoMicroware's OS-9 Level 1 had preemptive multitasking IIRC - this was late-1970s, early-80s - it was distributed by Radio Shack for the TRS-80 Color Computer line, which ran the 6809 8-bit processor, at something like .89 MHz (pretty f'in amazing when you think about it).
