The only thing I remember was that the board was about 12" x 16" or so
in size, some of the outputs were putting out voltage, it seemed to also
be the interface card for both the floppy and the HD, and that is about
it. I tend to try and get as much documentation as I can on anything
related to the 70's & early 80's computers that I mostly collect. Right
now, I just don't have the time to get into the machines the way I used
to. Hmmm, maybe that is a good thing :). At any rate, I won't be doing
anything with it in the foreseeable future except to keep my eyes open
for other documentatation.
