I have dumps of the ROM, as do a bunch of other people. They were
published in the manual, and the manual has been published to the web, so
I'm certain other people have typed them in, and I've handed out copies of
the ROM to a few people.

I asked Woz, and he said as far as he knows, the original masks for the
Apple-1 PC board no longer exist.

A schematic would have to be made from an original board. Unsoldering the
chips and sockets would be very intrusive and I doubt you'll find anyone
willing to do that. Ideally there would be some other non-intrusive
method. X-ray perhaps?
