Oh, oops. That went completely over my head. I missed that detail entirely.

So the minicomputer vendors in the 80s typically used twisted pair
ribbon for these things, as in the 1700/50 stuff Glen was talking
about. I don't know how long a cable would need to be for that to be
I got a great pair of cables for this project.
50 conductor, 50 pin IDC, 10 feet long.

Cost was $35 all in for the pair of 10' cables. Not bad considering 50 pin
ribbon isn't cheap plus connectors plus time.

I would think so. I was an occasional VMS user at DEC, and I somehow got
myself
This guy seems to have gotten a bunch of stuff from someone making QBus stuff
probably MDB, Dilog, or someone else in SoCal
I did decide to get the Wilson Labs RL01 emulator he just listed.
The MDB chassis seem to have 11/23s and RLV21s in them.

Oh, I forgot - the problems with all CM-2s is that they are
fantastically useless machines. The SIMD hypercube architecture looked
good on paper...

Most were 16K machines, I think.
