For drawing the pcb you would need good quality scans (150 dpi full
size) of both sides of the original Apple I. That means someone has to
take his board out of the safe, remove the big ICs, put it onto his
flatbed scanner, and take photos of both sides. 
Most Apple I were fitted into wooden boxes and someone who paid $20k for
this machine would hardly disassemble it.

This is the first problem. The second problem will be getting Valvo 2519
and 2504 PMOS shift registers. If anybody knows a source for these, tell
me.

Nevertheless it is possible to build something that behaves like an
Apple I. All parts for the CPU (sheet 1) are still available, in the
terminal section you will need a replacement for 2513 (use 2716), 2519
and 2504. This would be the first Apple I clone.
