The complete schematics of the Xerox Alto are on Bitsavers. I don't think photos would help a lot with generating a PCB, since the chips cover much of the wiring. A bigger problem with a Xerox Alto replica is the wire-wrapped backplane. It would be a pain to redo that by hand. For most purposes, you'd be better off using the ContrAlto emulator.
