    Oh God, it looks like the illegitimate mutant child of a PC-Jr's sidecar! Probably seen better days too. I'd love to see what's inside it!
    My vintage systems: Tandy 1000 HX, Tandy 1000 RSX, and some random Pentium in a Hewitt Rand chassis...

    Some people keep a classic car in their garage. Some people keep vintage computers. The latter hobby is cheaper, usually takes less space, and is less likely to lead to a fatal accident.

    A backplane, cards, and a switching power supply.
    The NGEN was weird in that all of the modules take a 36v power brick and regulate down to what each module needs.
    The backplane is sort-of Multibus. They patented it.

    Yes, you're at it; it was called "Bull Questar" in France.

    ==> I remember the power bricks laying all around and the horizontal assembly…. and the CTOS name.

    Thanks to both of you for pointing WallyB to me in this thread. He has reached out to me by email, and we are planning on working out a way to save this piece of an NGEN System. It's true, my restoration work is bleeding over into those, which is a very interesting thing indeed. I hope to have examples of all of these vintage Convergent machines working again someday soon.

    I'll post updates here as I'm able, and have anything to report, for any who might be interested.

    We're still trying to find it. It was handed off to a support company in India, and disappeared without a trace.

    CHM has several generations of the system, as do I.
    Documentation and binaries for the system are on bitsavers under convergent

    The 68000-based Unix systems aren't as common. AJ Palmgren's site is probably what you're thinking of

    I have all of his pictures from inside the plant and offices of Convergent featured at the bottom of my site at http://MightyFrame.com , if anyone wishes to peruse.
