Lately I've been having problems with my Mega's keyboard. More specifically, the 'e', '1' and 'q' keys do not want to respond to a keypress and have to be coaxed (by repeated pressing) into giving me a character. Is there any good solution to this problem short of replacing the offending keyswitch? (assuming that's the problem and not some odd chip in the keyboard). This is driving me nuts, especially the 'e' key! I took apart the keyboard, but can't get to the internals of the switch, short of unsoldering and removing it from the PC board. Has anybody had this particular problem? -- Jonathan ...ucbvax!cory!jlemon or jlemon@cory.Berkeley.EDU

My 520-keyboard did the same after 2 years of use. Cleaning the contacts didn't solve the problem. Replacing the 40-pin socket for the 6301 processor did solve the problem. If You do not dare to un-solder the socket, try to pull out the processor, plug a gold-plated (expensive) socket in and plug the processor to that. The pins of the socket have a greater diameter, so they get more pressure and better contact; the gold plated socket does not corrode as much as the tin plated ones do... hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Dennis had stepped up into the top seat whet its founder had died of a lethal overdose of brick wall, taken while under the influence of a Ferrari and a bottle of tequila.
