The Columbia PC (first DOS 'workalike'- not fully PC Compatible, with ISA slots. Any of the machines that ran MS-DOS 1.x on 8" floppies. Any of the early 'MS-DOS' clones, i.e. the Panasonic PC, that aren't fully PC-compatible and thus require their own special MS-DOS version. Tandy 1000's 'just barely' qualify here, because they were so common. And: the HP 95LX is 'cooler' than the 100LX and 200LX, though less useful, in that it doesn't have a graphics mode, so is a primative text-only palmtop. And because of that it's really cheap these days, < $20 on eBay if you look hard. The HP Omnibook 300- DOS and Windows 3 in a PCMCIA ROM- execute-in-memory so that it runs DOS, Windows, Word, Excel directly out of the ROM without loading it into RAM. A major technical accomplishment that was a dead-end development effort. CP/M-86. ------ A lot of the above are cool more as 'weird relics' than as anything technically neat.
