    Possibly the CompuStar beast (in some configurations): https://www.ardent-tool.com/CompuStar/CompuStar.html

    And probably some other...

    I imagine that many of the "no-name" MCA clones were based on this
    chipset as well (or one of its brothers). But most of these machines
    were either just a "paper launch" or actually shipped but are long lost
    in the sands of time.

    Hey there,
    just stumpled across this one: http://bitsavers.org/magazines/Mini-Micro_Systems/198803.pdf Page 12 - following. I'm wondering, if they ever built some machines around this C&T Chipset :O

    I'm aware, Stefan, believe me. I've seen a nude virgin riding a unicorn.
    Twice. But only one Reply board so far...

    The Mini-Micro Systems article is in our stash now: https://ardent-tool.com/docs/articles.html#MM_Systems
    Thanks for posting this!

    P.S. Anyone needs a unicorn?

    Hi Tom,

    thank you, as always. I didn't notice these Reply Boards had these chips. As you propably know, these Upgrade-Boards are not that common here in Europe :(

    Second, Chips has added four programmable decoders that let OEMs avoid
    adding discrete logic devices to control such things as panel lights,
    password control and networking support.

    Third,
    the article had a massive complex about compatibility (the part they stated, you could easily place original IBM ROMs instead of the C&T ones) - now i'm curious what happens here with the bull micral - maybe Headland had the same intention as C&T? From
    your perspective - what's the closest match to a PS/2? I'll test the Model 70 (non cpu-daughterboard, non cache variant) ROMs first - and of course i use parts that are at least electrically compatible :)
