Phreakout, Apple confidential is wildly speculative and contains some biased inaccuracies based on who they were able to get statements from at the time. Granted we all go on available sources, but Woz didn't actually say that by your own admission. Plus there is a bit of revisionist history with all of these characters. However, the thermal issues were debunked by Manock himself in a lecture, where he discussed the sophisticated tests used to prove the problems lay elsewhere, since everyone pointed the finger at him immediately. In fact it was Manock's tests which led them to scrutinize the logic board more closely and discover its microscopic flaws. The myths persist, because nobody really cares about how something is resolved, they tend to run with the first thing they heard. The real failure of the Apple III was that after the initial launch the sales and marketing people wanted nothing to do with it, so there was never any effort put into clarifying what the real problem was, and thus it died, with most everyone remembering it was because of a poorly designed case.
