[comp.sys.mac.hardware] Intermittent key repeat problem

strub@cogsci.ucsd.EDU (Hank Strub) (01/14/91)

A Mac II in our lab has a strange problem that's frequent enough to
be irritating but too intermittent to take in for service.

Once in a while when typing, a key will repeat until the next key is
pressed.  Rebooting does seem to help, but the problem is infrequent
enough that it's not clear if the reboot is doing anything.

We've swapped (extended) keyboards with another Mac II and that's what
makes me think the problem is in the Mac (or the cable).


Any suggestions on things I can do, or point a tech to?
San Diego hasn't had especially low humidity so I don't think it's
static electricity.
Is there enough space in the ADB ports that I'd do something if I
sprayed them with contact cleaner?

Thanks in advance,
