Siemens KCM – Knowledge Crunching Machine
We got hold on one of the rare Siemens KCM machines. The "Knowledge Crunching Machine" was a joint research with ECRC. The European Computer Research Center was based in Munich/Germany and founded by Siemens (Germany), Bull (France) and ICL

@behindtheconsole Whow, this looks like a very complex AMD bitslice-based design. It seems to have 32 MB of RAM, quite a lot for 1989!
A paper about the machine can be found at https://dl.acm.org/doi/pdf/10.1145/74925.74947
By coincidence, my former boss Peter Marwedel and his students at Uni Dortmund designed an ASIC implementation of the Warren Prolog virtual machine in 1989/90. I have two of the surviving chips and made some die shots, unfortunately most of the documentation was lost.

@me_ we are currently looking for a Siemens mx300 to get the software running. And the clear the tantal and power supply. And maybe we can hook the two together and try to bring it back to live. We know about the paper and have already copy.

@behindtheconsole I think I have a Multibus CPU and ethernet board from either an MX300 or MX500 with NS32532 CPU here. No idea if these still work and I don't have the rest of the machine, but I would certainly donate the boards for your effort.
I would expect that there is an interface card required on the MX300 side, too – do you have that one?
I guess you know Udo Möllers NS32k web page already? http://cpu-ns32k.net/

@me_ Yes, I already had contact with him once. But have to get hold of him for this project.

@behindtheconsole Regarding the MX300, a few people on the VzEkC forum might have an MX300, at least there were some discussions in 2022. I hope I'm not simply proposing things you already tried...
