- OS/9 ran on the CoCo-1 much earlier (and on non-home computers back
- around 1980 or 81 I think?).
- But if you stretch the definition of both 'multitasking' and
- 'Operating System', then the ZX-81 qualifies, I think - the Z-80 both
- drove the display, and ran programs in the retrace interval. And it
- was only $150US (actually, it did this *because* it was only $150US -
- it only had 4 ICs in the entire thing - Z-80, RAM chip, ROM chip, and
- glue logic).
