Yes we've heard of the computhink disk drives for the pet, but does anyone know anything about the existence of a computhink computer, as I have just gained a set of nearly complete boards for one! (about a dozen TTL ICs missing). It's a 6502B based machine from about 1979/80 with 64k of ram and a disk board (probably 8" floppy from the connector). it looks like it's supposed to have an integrated crt sitting between the daughter boards.

But here's the strange thing....
it's a 6502 machine, but the roms say "tested, ms dos 1.1" on a sticker????
Is that just an odd sticker, or was there really an msdos for 6502s? I can't imagine how, as the interrupt structure is completely dos incompatible, or did it somehow emulate the 8086? All the same, the sticker looks like it is supposed to be there .

Also anyone have any info ... schematics... photos .... links ....???

Perhaps it also had a 8088 daughter board? A more funny explanation is that someone tested to boot MS-DOS, but didn't succeed... :-) A third explanation is that "ms dos" does not refer to Microsoft's DOS, but something different using the same abbreviation.
