VM – CP/CMS – VM/SP is 40 years old…

Wow mainframe stuff is ‘getting up there’.. VM was released August 2nd 1972.

There is no doubt about the importance of this OS, as it brought virtualization and paravirtualization to the world 40 years ago.  And a lot of these concepts found their way to “minor” things like the 80386, OS/2, and even Windows/386 .

Ages ago I managed to get a copy of Dungeon/Zork running on CMS, but other than that I don’t have any other exciting mainframe software…

What is there to tell? I’ve loved UNIX like things since I was first exposed to QNX in highschool (we had the Unisys ICONS!), and spent the better time of my teenage years trying to get my own UNIX… I should have bought Coherent in retrospect.. Anyways latched onto Linux in 1992, and then got some old BSD admin books and have been hooked on the VAX BSD & other big/ancient things since…!

  1. Wow! That mainframe is so old.

    Official builds of Qemu 1.1.1 is out, BUT for some reason…the Windows official builds aren’t working properly. Have you tested Qemu 1.1.1 on Eric Lassauge’s site, yet?

    If so, please post back if you report any problems.

    The good news is that Qemu 1.2 will be out soon. RC0 seems to work better than Qemu 1.1.1. 🙂
