I've got an Intertec Superbrain sitting around on my desk in London but no software for it - that'd make a pretty nifty OPA0 too I think.

I think the drives are fubar'd though and they're some weird quad density format, so I thought I'd _carefully_ disassemble the machine and put like a modern machine into the casing, booting into some souped up CP/M emulation thingie...

I'm kinda shocked to see that you wouldn't be able to run NetBSD /on/
a VT180 ;)

Z80...no MMU, 16-bit address space   

Ah, right. I keep forgetting how old the Z80 actually is   and the fact it doesn't offer too much in the way of anything beyond small embedded stuff now.

Hmmm, I've been reminded of that project someone accomplished once: simh + a phone + a vt100.
But instead someone could go: simh + raspberry pi + VT180 ;). Hide the pi within the cabinet, implement a little piece of software to go between simh and a real serial interface (or can simh interface directly now?) and run VMS "in" a VT180.


Was CP/M in ROM on the VT180?

Nope, booted from 5.25" floppy from an RX180 disk subsystem.   You'll
be able to see one when you come visit, though I can't find the floppy
cable.

Aww, shame you can't find the cable. :(
