I thought PC-DOS was MS-DOS that was bundled with the original PC AT.

  IBM still bundled it with their Pentium equipped machines. My machine was a P75 equipped box with 16MB of memory and it came with PC-DOS. It came with an ansi-gui application for figuring out what to stuff into high memory and its own version of HIGHMEM.SYS. IIRC you could get 610KB of regular memory free even with the CD-ROM, Mouse, and SoundBlaster drivers installed.

    That ANSI program sounds oddly familiar, but I never owned honest IBM PC. I started out with a second hand 486 based clone (complete with MS-DOS and Win3.11 on floppies), after having been an Amiga 500 kid for a number of years.

      Maybe you're thinking of MemMaker.exe (bundled with MS-DOS starting around version 6)

        Yep, seems so. Seems the PC-DOS program did the same job, but had been developed by a different company.

  And the original PC from 1981. I think strictly speaking PC-DOS came first and generic MS-DOS came second. MS developed the OS for IBM and their biggest coup was negotiating the right to still own the IP and sell it to others as well.

    Really sorry about the dupe - The lesson, as always, don't use the phone for Hacker News. Didn't notice until it was too late to delete. I wonder why they aren't automatically deleted?
