That would make sense since the 32016/32032 series were meant to be chained
together. I am pretty sure some people had a shot at multiprocessing with
them, god that must have been a laugh... 

I wouldn't mind a copy of the schematic for the cheese wedge, just for the
interest's sake.

Does anyone out there have copies of the Acorn Z80 2nd Processor discs ? I
seem to have mislaid them. If someone would be so kind as to e-mail them to
me, put them into a BitTorrent or load them up to some free web space it
would be most appreciated.

Has anyone OCR'd the Cambridge Co-Processor Manuals ? I might have a go, I'm
OCRing Micro Users at the moment to allow searching on the content.
