Another option for the second and third problems
is to contact Woz and
see if he would be willing to help. I have so far restrained myself
from emailing him, since I know he gets tons and tons of emails,
including people asking him if he has an Apple 1 he could give them,
etc. I'd imagine Woz would very much like to see the Apple 1
preserved, but it would probably take him quite a bit of time to find
all the docs and info that we'd need.
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?
Any traces that go underneath components won't show up well on an X-ray
(well, from what I've seen anyway). DIP component leads don't end at the
edges of the package, so it tends block the image. There are X-ray viewing
systems intended for SMT and BGA work that might work for some things, but
they cost a small fortune.
I'm probably one of the few that would be willing to take such a board to
bits (but I also mentioned that before). Of course, that would be *after*
I get myself a Metcal MX500 and DS1 ;)
