Rod Holt helped Woz build the Apple ][, and was then responsible for its design and manufacture, he was one of three VPs when Apple incorporated (Jobs and Woz were the other two) and he was in charge of the Macintosh group when it launched.

An old engineer friend of his asked Holt about several topics, and I think his answers were interesting, including what was baked into early Apple that made it succeed at what it was trying to do over the years.
