I think it ranks as the second most complicated machine I've seen. Most
I've seen are much more like the PERQ in spirit: alu, registers, simple
sequencer, straightforward muxes.

The internals don't appear to be documented in anything I've seen so far.

Should be done soon....

They're among the PDF files from Al Kossow's site. TechRef_b?_???.pdf and
IOPschem.pdf at least contain schematics; I don't know how complete.

Ghostscript appears to read the files fine and ought to be able to save
the contents in Postscript or other form. If you have no better means,
I'll eventually send you a printed copy.
