IBM PC celebrates 25th anniversary
DOS 1.0 Running
DOS 1 was such a crude and simple operating system as compared to later versions or even CP/M. It was, however, easy to learn and starting from 1.0 meant that I only needed to learn a bit of new stuff with each iteration.
DOS 1.0 did have a nasty math bug, though, that was fixed by a patch - version 1.05. I've got a copy of that as well. IBM never officially released that version, however. It was just a bridge version until 1.10 could be shipped with the fix and some new features.
