Apollo Uplink Box Progress
🕑 Added 2021-09-23 00:34:20 +0000 UTC
You might remember our mystery uplink command box that we got from Marcel, completely undocumented, full of weird modules and with some parts missing. Last time I posted about it, I had barely managed to manually trigger the paper tape reader. In the meantime, Ken has been using his mad reverse engineering skillz to figure out the box.
Ken has several Twitter threads reporting his reverse engineering efforts, here is one of them:

Last week we finally made enough progress that we were able to load a command from the tape.

Excellent. Will have to take a look at it when it's a good time :)

We have a good inkling of what they should be from a drawing that shows the bit patterns. Ken figured out the sub-bits by looking at schematics. We also have the uplink decoder that goes into the spaceship. Some commands flip about 100 relays around, some are for updating the clock. The most interesting ones are the ones that go into the AGC. You actually just send DSKY keystrokes!
Do you have docs on the commands available? If so, is there a link that points to them? BTW: Nice progress sleuthing....
