I bought it. I know it's long odds that I can
get it to do anything,
especially without that daughter card, but, waddahell, it's an
interesting DEC PRO collectible. I reckon I'll plug it into a PRO and
see if it responds to attempted accesses. If the ROM contains PDP11 or
VAX code, I'll disassemble it and see if there are any clues there.
Good. If you can check that square chip top center and let us know if
it's a 80186 or something. It would be interesting to see if the ROM is
Microvax code, CTI code, or that other chip's code.
