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.
