Re: [TUHS] MS-DOS

​>I don't think they cared. or felt it was needed at the time (I disagreed then and still do). MS-DOS was a better choice at the time than Unix. It had to fit on floppies, and was very simple. “Unix is a system administrations nightmare” — dmr Actually, MS-DOS was a runtime system, not an operating system, despite the last two letters of its name. This is a term of art lost to antiquity. Run time systems offered a minimum of features: a loader, a file system, a crappy, built-in shell, I/O for keyboards, tape, screens, crude memory management, etc. No multiuser, no network stacks, no separate processes (mostly). DEC had several (RT11, RSTS, RSX) and the line is perhaps a little fuzzy: they were getting operating-ish. It all had to fit on a floppy (do I remember correctly that the original floppyies, SSSD, were 90KB?), run flight simulator and some business apps. MSDOS lasted a decade, and served the PC world well, for all its crapiness. Win 3.1 was an attempt at an OS, and Win 95 an actual one, with a network stack and everything. I’d be astonished if he had anything good at all to say about C++. He’s still around…you could ask him...
