    Why not place some Windows machines inside a computer room if they can

    I have not been hands-on close to IBM mainframes since the OS was called
    MVT, but I am pretty sure that real 3279's are long gone, except in the incarnation of tn3270 (3270 over telnet). And I suspect the console
    complex is a PC "service processor". I wonder if it runs OS/2?

    IBM stopped making terminals some years ago.

    Yes, thinkpad with OS/2 Warp on a z seies

    Wow! I didn't realize this was still true. I can see the point in using
    an OS that's 100% under IBM's control, though.

    This is not still true. From the Z9 onwards its Linux based...

    I remember the weight of a 3279 graphical terminal when I worked in IBM
    World Trade Asia Corp.! It's really heavy and big! :)

    I also touched many PS/2 computers physically. They are no more now. But
    I like their metal chassis... no glass.

    How quickly we forget .... or is it just that sooooo many 'BAD' things

    We certainly remember the event, but I had to google the date too.
