    Looking for the PDP-8/I Control Panel Assembly Bezel Casting drawing

    I am looking for the PDP-8/I front panel bezel casting drawing, for a possible project to recreate the bezel in 3-D printing. I looked on BitSavers in the /PDF/DEC/PDP8/ section and I see that the PDP-8/I Assembly Parts List is drawing A-PL-8I-0-0. There I see that the Control Panel Assembly...

    Altair 4K RAM Board???

    FS: Unique IMSAI

    This IMSAI system is a good, working IMSAI with Front Panel, original IMSAI 8080 CPU board, and a clear plexiglass cover. I think it's pretty unique. And, it keeps the dust off of everything inside while still allowing one to see what's in there. Quite an advantage over never putting the cover...

    OS/2 Warp - which one?

    Long, long ago, I had a generic desktop PC with a 486 DX2-66 CPU. I tried a lot of OS experiments with it, Windows 3 (of course), Windows 95, various versions of Linux, and OS/2 Warp. Recently, I decided to resurrect OS/2 Warp, but I found that somewhere along the line, I must have gotten rid...
