I have a related problem and thought that those who read the original
article might be able to help.  My son discharged a static charge from
his hand to the joystick of our Comm 64. after which the machine
continually echoes spaces after boot up.  Most of the keys do nothing.
The machine is unuseable, even with cartridges that don't need the
keyboard.

I remember a while back how other subscribers to this newsgroup
had complained of static fouling the joystick ports and a hardware 
fix for the problem.

Anyone have a clue what chip or component I should look at?  I really
don't want to "log a service call" on the machine.  I'd be very
grateful for any help or advice.
