I am looking at the broken keyboard of a friend (old 512k style) which has several dead keys (Q,S,D,[,],;) - I'm trying to remember where I may have read about analyzing such problems. does anyone else remember a write-up on keyboard hardware? it may have been a User's Group newsletter, MacTutor, ...? where I had read a "useful" article about keyboards ... anyway, my guess is that it's either one of the chips in the board or a broken trace somewhere on the board ... thoughts, anyone? in the meantime, I'll try to find some spare chips ... -- --------------------> PREFERED-RETURN-ADDRESS-FOLLOWS <--------------------- (ARPA) werner@rascal.ics.utexas.edu (Internet: 128.83.144.1) (INTERNET) werner%rascal.ics.utexas.edu@cs.utexas.edu (UUCP) ..!utastro!werner or ..!uunet!rascal.ics.utexas.edu!werner

I received a pointer to a recent MacUser - and was able to confirm that I must have been thinking of an article I had read in the July '88 issue, which explained quite well how to deal with a broken key; however, it did not address the more likely problem in the board I am looking at, a broken trace or dead chip(s) ... I'm nearly sure I read something in a long-ago MacTutot or UG- newsletter that addressed that topic ... thanks to all who responded - more info when I find it ... report on outcome after the hurricane "Gilbert" has hit Texas; of course, it's the largest, meanest, badest .... we won't have it any other way around here (watch out Corpus Christi; I think your number is up ... I figure it will hit go after the Mac home in the Brownsvile-CorpusChristi area ...) -- --------------------> PREFERED-RETURN-ADDRESS-FOLLOWS <--------------------- (ARPA) werner@rascal.ics.utexas.edu (Internet: 128.83.144.1) (INTERNET) werner%rascal.ics.utexas.edu@cs.utexas.edu (UUCP) ..!utastro!werner or ..!uunet!rascal.ics.utexas.edu!werner
