15.032 Today my IIgs started "stuttering"-- i.e. working for a bit then freezing for a bit then working again. Anyone have a fix?
I have seen this before. The cause was a bad connection to the keyboard's
mini-DIN-8 connector. One of the leads from the connector to the keyboard
circuit board had broken its solder connection; and, the line was
intermittantly connecting.
When one or more lines is broken or loose, information is not getting back
to the computer or is interrupted. Seems like the computer is waiting for it;
and, you get "stuttering".
The solution was to resolder the mini-DIN connection(s) on the keyboard. I
did it and all is fine.
The keyboard's min-DIN connectors are fairly well known weak spots on the
IIgs; and, I have repaired more than one keyboard for bad connections. In one a
copper trace going to a connector was broken-- repaired that by soldering in a
jumper made from a bit of solid copper wire.
