[net.micro.apple] IC TESTER AND 80 COL PROBLEM

hong@garfield.UUCP (11/12/85)

Except the screen moving problem, I meet another problem with
strange characters after booting for few minutes. Strange characters
appear randomly, like !, ', $...etc.
I don't know what happens, I exchange the Eprom with my friend's card,
nothing happens.
Would some experts tell me what happens?
Also, does anyone use a card called 'IC TESTER'?
Is it great to find out the fault of IC?
Thanks.
