<BTW: I also saw a Rainbow 100. Anything distinguishing it from any other
<CPM/MS-DOS machine?

It was a dual processor with z80 and 8088, the bus as not PC (ISA) and it
allowed 768 or 825Kw of ram. It was color medium resolution when the PC
was still mono. It's noteable in that it ran CP/M-80, CP/M-86 and MSdos.
When Running CP/M86 or MSdos the z80 is still operational and services IO
for the 8088 giveing it better performance for it's day.
