Charles West noted the importance of adequate cooling.  Heat buildup
has caused erratic performance in several Kaypro models.  In addition
to cleaning the fan filter, a good check is to remove the metal cover
and run the machine in the open, especially when the ambient room
temperature is high.

Controller chips can get too *cold* also!  When Plu*Perfect Systems
was in Idyllwild we had a Kaypro 10 in a minimally-insulated basement
office.  When powered-op on cold (20 - 30 degree F) mornings it would
often report as many as *100* bad tracks.  As it warmed up, fewer were
reported, and in an hour all was again well.  After that, we usually
left the machine running overnight!
