Very interesting video. I had no idea.
It would have been interesting to see how the program was actually executed. Do the rings around the rope core somehow create a circuit that allows the processor to "know" in which order the 1s and 0s are in? Or is there some kind of mechanical process?
It must have been very easy to make mistakes with all that manual work. I am assuming the weave must have had to have been checked many times.
- lazylester 12y agoI'm pretty sure the bytes are sequentially addressed, but the program (memory contents) may contain branching, conditionals etc to load the next address. Just like assembly language. If I recall correctly, the microprocessor logic on these missions was RTL (resistor-transistor-logic) which was the predecessor of TTL.

The AGC had it's own assembly language[1] and was a pretty recognizable general purpose computer[2] for it's time. 1: http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/apollo/public/archive/1689.pdf http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/a... 2: http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/apollo/public/archive/1717.pdf http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/a...
