• Flashback to S/360

    We know of AIX/370, AIX/RT, and AIX/PS2.

    PS/2s were used as terminals or workstations connected to AS/400 systems
    as well.

    Was there ANY connection of a PS/2 to a S/360 system? Maybe not
    directly, perhaps by using something like a 3172 or an interconnect gizmo?

    Bus/Tag cables are mentioned.

    That's what the seemingly ubiquitous 3270 cards are. They let the PS/2 connect to a 3174, 3274, or integrated workstation controller and
    function as a terminal emulator.

    There is also the bus/tag card which can be used to either "emulate"
    channel I/O (so you can hook up a mainframe tape/disk/controller to a
    P/390) or hook up as fast CTCA data path to a mainframe.

    We had one connected to a 9370 system running VM way back when.

    P/390) or hook up as fast CTCA data path to a mainframe.

    You could also hook up a PS/2 to a 360/370 system using an SDLC adapter
    as a SNA terminal (or printer) device, but almost no one did, the 3270
    adapter was more flexible and faster. Or you could make an async modem connection to a 3174, though again the 3270 was "better" unless you
    needed to access a system miles away from your location. I did this
    when I was required to provide off-hours support for a VM/HPO system
    where I was the System Programmer.

    And let's not forget about Token-Ring adapters for PS/2 to 360/370
    system connectivity. Once they were in common usage, almost everyone
    dropped the 3270 adapters, since you could do both terminal emulation
    and TCP/IP with the Token-Ring adapters -- same with an Ethernet
    adapter, but most IBM shops were Token-Ring for YEARS before switching
    to Ethernet.

    IBM offices circa 1987 were a sea of XT 3270s with the occasional AT
    3270 and PS/2 with a 3270 adapter card in it. If you had a PS/2, it was
    really nice because it could use expanded / extended / "XMA" memory to
    let you run more simultaneous 3270 sessions. By 1989 most people had a
    PS/2 on their disk. My had a Model 1 Type 80, with an absurd number of
    memory cards in it.

    By 1989 people would also be running OS/2 Extended Edition, which made
    the multitasking a lot easier and had a nice GUI for all of your 3270 sessions... and the 3270 adapter cards were getting replaced with Token
    Ring cards, and the 3270 protocol spoken "natively" over that.

    Yes, I had a 3270 AT/GX with the 5379 color display and simply loved it
    as it gave me lots of 80 column, 50 row 3270 sessions (4 on the 3270
    adapter, 4 on the Token-Ring adapter) and the screen refreshes were FAST
    - a System Programmer's dream. The powers that be dropped a 8580-A31
    with 8514 display and 8514/A adapter running OS/2 EE and told me to use
    it instead of my old "clunker". I tried it, found it slow, and kept
    running my 3270 AT/GX until OS/2 Warp 3 came out and I finally put the
    3270 AT/GX to bed. By then we were up to 9590-DLG units with XGA
    graphics, which was "good enough", even though the 3270 AT/GX still had
    the edge on 3270 screen updates.

    Terminal emulation (or just an OS/2 Window) on an 8514/A is sloooow and
    a sad idea. It's sad they didn't optimise the 8514/A for text. But they
    just didn't.

    IBM put really great hardware on people's desks back then. The 8580 I
    mentioned was my dad's. I think it counted up to 16MB - it must have
    been crammed full of expansion cards.

    Oddly enough, when I worked for IBM, the computer on my desk was a Dell
    Pentium 90, which the other IBMers who had the completely loaded Mod.
    77s that had been bought a few years earlier were envious of us since
    mine was just plain faster. You can probably guess which division I
    worked for.

    If there were anything I could go back in time and "rescue" from there,
    it would have been the gas-plasma 3270 screen that could show 4 3270
    sessions at once.

    The 3290 and 3295 plasma monitors were interesting and I used one as a
    system monitor for a while, but having the full range of colors was
    nice, too.

    I've got a 3290 and it is to me kind of astonishing. What was the 3295?

    Same idea as the 3290 in a slightly different form factor, it also
    included the start/stop box for use as a system monitor.
