Is there any real reason why the older versions of MS-DOS (eg 3.3 through 5.x) are needed by anyone? I think any computer that can run 3.3 should be able to run 6.2 if you've got the right disk drive (size and density). Am I mistaken? My oldest XT, with 360 K 5.25" floppies, ran MS-DOS 6.22 just fine. My Tandy 1400 laptop, with no hard drive only (2) 720 K 3.5" floppies, runs MS-DOS 6.2 quite well.
I understand from another thread that after DOS 6.x, DOS itself is a hidden part of Windows. I suppose this means that there is no real seperate MS-DOS after 6.x. As another post said, DOS in Windows 95 forward is an emulation of DOS, not a seperate OS upon which Windows is an overlay.
However, what about Dr. DOS? I think that third-party OS was up to version 7 but I really don't know (a) how compatible it was with any MS-DOS programs, (b) what the last version was, or (c) how useful it would be even on XT-class computers (8088 chips).
