Yes, but back in the UK so it'll have to wait (from me) for a few weeks. Same 
with the BBC-side ROM if that's needed. Stupidly I was a bit last-minute in 
mirroring useful data off my fileserver before leaving the UK and managed to 
leave all of my Acorn and Torch stuff behind :-(

I've got the schematics for both boards and the "memory management" (such as 
it was!) PAL equations somewhere, too. I *think* only the Atlas boards would 
run UNIX; the Neptune boards didn't have enough memory to be useful (and the 
PAL logic for the memory mapping was different anyway)

cheers
