I finished setting up my Apple II following a move and everything was initially functioning normally.
While keying in commands, some keys started repeating on occasion. Then some keys would repeat several times, followed by one repeating without stopping.
Rebooted to normal prompt. However no matter which key was pressed, no characters were displayed on screen. Reset appears to work normally.
I did find a report of a similar problem in the forums but it did not appear to have been resolved.
This is an earlier Apple II (serial 734) with original keyboard.
Note, my hardware background is limited to pulling/inserting ICs and expansion boards. I no longer own any meters, so very basic instructions (including what meter/settings to use) would be appreciated.
