What did the XEROX box look like? There was an odd looking box in the
samje carton that I found the XEROX 820 manual in. It looked somewhat like
an Apple Lisa and had a large 12 - 13"?) screen offset on one side of the
case. I think it also had a notch in the bottom front like the Lisa but it
did not have any feet sticking out like the Lisa does. I looked all over
this one but couldn't find a name on it except I could look through a grill
on the back and see the name "Ball". (It probably had a Ball monitor in
it). There was no keyboard but I think there was a socket in the rear for
one to plug in. There was also a large (50 pin?) ribbon cable hanging out
the back. I'm guessing that it may have been used to connect to disk drives.

Thousands of these were sold as bare boards with

ran into folks using them, yet never saw one in the original Xerox enclosure.
The Xerox box was just too expensive. Once they were no longer a major
product,
they were surplussed out as bare boards. I think it was through BG Micro.

Subject: Xerox 820
Hello all,
Recently I acquired a Xerox 820, but as a single board, w/ power supply. I
also received many docs (including a tech manual with Monitor listings and
schematics). I know originally these were "all-in-one" computers, but many
appear at ham fests in exactly the same shape as mine -- as a single board
computer.
Of course, hooking a terminal up to it produces nothing (even testing at
different baud rates/parity/stop bits, etc), so I'm wondering:
- Are there any modifications (ROM or jumpers) to "convert" this to use the
serial port for a console, rather than the keyboard and video display? I
couldn't find anything in my docs, but of course, I have not read them in
depth yet.
In return, I could offer copies of the docs, or thanks to 22NICE and my
Compaticard (thanks Don!), copies of the files on the diskettes (CP/M,
"Word
> Processor", "Diagnostics", "Training Files" and
"Program Files"), or images
> of the disks (assuming Teledisk could do it -- I haven't tried that yet).
