Interesting suggestion - we have a number of VME crates with CAN bus
capability - not the CPUs on the VME bus, the crates themselves... I
think it's used for environmental monitoring and control in this

IMPs - Internet Message Procesors. I'm blanking on the first generation
hardware, but later IMPs were PDP-11-based.

Certainly, the less external hardware, the more likely someone else will
give it a go. If the end result is an application that will run on, say,
eight C-64s, I might try it when I get home. If it's more of a 32-minimum
or 64-minimum, that's a bit more hardware than I have access to.
