I've now wired up most of the memory board for the Replica 1. I started with the address decoding and control lines and confirmed that it worked (e.g reading addresses in the correct range generated appropriate chip select signals as observed on an oscilloscope).

The wiring is rather tedious and time consuming. I might consider wirewrap for future projects, although the end result doesn't look as attractive with the big wirewrap pins sticking out of the back of the board.
I'm also continuing to tweak the Apple 1 BASIC source, adding comments.
