A few highlights:

- photo #2 shows the construction of literally hand-weaved read-only memory for the 36,864 words of fixed program memory. Literally weaving wires through (or bypassing around) tiny magnetic cores for each bit of storage. Must be re-weaved for a new "build"

- photo #10 shows the prototype, occupying many many racks (not yet miniaturized!)

- photo #20 shows characteristics of the machine (2048 words of writable memory; 575us for a double-precision multiplication)

- photo #24 https://www.youtube.com/watch?v=_gIrELUMtp0 (32 seconds) shows large-scale breadboarding before the computer logic design was miniaturized

- https://www.youtube.com/watch?v=F1-KBKaCiMM (4 minutes 28 seconds) gives a nice overview of the AGC challenges
