One issue is weak picture
tubes in the displays -- the monitors are powered on with the system and
have no separate off switch, so they tended to get a lot of hours put on

I found my copies of the Ball HD series service manuals, I'll try to get them
uploaded today.
Xerox used them in the original expansion foam cased 8010 monitors.
The ones Fuji/Xerox used that are in the smaller plastic cases are more
reliable, but I don't have any documentation for those.
