Subject: trs-80 model 3 question
I have a trs-80 model III. It seems to work ok except that some of the
characters on the screen are wrong...the computer works even though some of
the characters on the screen are wrong (and they seem consistently wrong...a
"?" always displays as the same bad character.
Does this sound like video ram? Or something else?
Any troubleshooting info out there?
Thanks.
