Wow, nice setup. Reminds me of the setup I used to get my OS disks.
2 64000 mainframes, a fridge-sized hard drive, huge printer, and I
think one of the luggable 64000's packed into this little storage
room. After I got my 64000, I begged the professor in charge of that
room to let me make copies of his boot disks.

HP went to a lot of trouble to make sure NO ONE found out anything
about the CPU. I've picked up the impression that it's a straight
16-bit CPU (16-bit data bus, 16-bit address bus), byte addressed.
The 64000 was for cross development and HP didn't want you doing
ANYTHING else on it.
I've never done much more than play around with the 64000. Without a
hard drive it's pretty much a toy. The floppy drives are proprietary,
so I couldn't just add a couple more 360K drives. I tried.
