Do you want the hardware programming specs, or the circuit diagrams? It's
basically a couple of FIFOs. I have the programming specs (used them to
implement the second processor support in Elite-A :-) The copy I have is too
poor to scan and OCR, but I can probably extract the relevant bits and post
them here.
