Subject: Need information on Diablo/Xerox 3000

Hello all -

I have nearby a working Diablo/Xerox model 3000 word processing unit.
It came with several single-sided 8" diskettes, none of which can be
read on my trusty old XOR S100 machine with it's WD1797-based disk
controller.

One of the diskettes is labelled CP/M-80.  Thats the good news.  The
bad news is the system doesn't recognize the disk.

The hope is to convert this system for use as a BBS for the hearing
impaired.  To do this, I have been hunting for a technical manual.  I
would like to know the backplane pinout and I/O port addressing for
the serial/parallel ports present on the machine.

I have been on the phone to one division of Diablo/Xerox after
another.  I have been shuttled from one long distance call to another,
finally completing the "loop" by the last-called division saying to
contact the first-called division.

The machine _is_ old; circa 1980.  But I am hoping someone _out there_
knows something about it or can refer me to the _right place_.

Your help is appreciated.  Please e-mail your information.  If there
is any interest, I will summarize to the group.

Regards,
Mark Becker
