So I figured out which points on the backplane expose the up/down links in my topology diagram. I knew they were exposed there, just had to identify them exactly.
Unfortunately the pins are too short to attempt wirewrap so I just soldered them.

You'll be running your own AI on it soon enough!
It seems like we're not in short supply right now :-)
A contributor on the ATW800 channel has actually done this (running a very very tiny model, on the root Transputer) as an experiment.
Nice, is there a link to that at all please?

They're only 20MHz - but each one (each CPU) has a pretty fast FPU and 4MB of RAM, which is nice!

I have no idea what the discord channel's policy is on posting invite links (bots etc.) so I PM'd you. :)
