Thanks for that information. I'll take it to heart.
I am not as gifted with the wealth of knowledge you have, TechKnight, but I did wet through years of experience with electronics as far back as 1969, pulling tubes out of dead TVs and radios to fix others. Things were simple then, esp. for a 7 year old who like looking at a glowing get of tubes instead of the cartoon at the crt's face. From there to CB and Ham radio, and then computers with the Commodore PET. Electronics was a bit more than a hobby, as was computers. I became one of First Star's #1 programmers, earning a couple of million on the video games I did then, the money would be gone before 1999. Thing is, the Computer industry in those days were raw. No one knew how to fix them, and those that did were self taught. That is what I did - tech myself how to fix dead or broken machines with a multimeter, a logic probe and a soldering iron. I became good at it. Two 74LS125 on an Atari 800 and XL Series blowing out would kill a keyboard. Thing is, why are they blowing out at the same time together? And the Apple II/II+ used a separate microprocessor for its keyboard decoding, but that is not part of the IIe/IIc system.
I became apple certified and fixed the classic macs in those days and then taught students who to do it. I would be hired to be a comp tech and instructor for the Bored of Ed and stayed with them for almost 30 years. That is where I learned all my Mac stuff as it evolved. Joined the NYC Mac User Group and earned a rep as one of the best, though I did not consider myself as such.
20 years later here I am- BOO!
A lot of the things changed. One did not expect for caps to fail in those days. Now its part of the scenery. There is a lot for me to learn. SMD/SMT I got a general grasp of. But electronics today, everything is modulized, if a module fails, throw out the whole thing and buy a new one.
So thanks for the information.
