Got this whole thing wired up, started testing. GUESS WHICH DUM DUM WIRED IT UP BACKWARDS?
As an aside, I am #3dprinting these hard-to-find 23-pin D-sub shells. I’m actually using crimp contacts in them, since they’re still available (even new if you want to pay $0.40/contact - I got these from a surplus seller). The contacts push into the shell, and the crimp tails are soldered to the board. The shell is also has a retention flange that prints at an angle so the shell can be printed without supports.
The parametric model is here: https://dominionofawesome.com/obj/parametric-dsub/. If you’re looking for contacts, these are TE (formerly AMP) 66503.

@nprofile1q... Is the San Francisco Terminal vt100 compatible?
@nprofile1q... I’ve heard NetBSD has a pretty clean driver system. Interested to hear how it goes for you.
@nprofile1q... The PCB looks like it can also take the usual microswitches you’d find in a mouse. But it doesn’t sound like it’s worth retrofitting it. Looks like a very fun project, though!
I have acquired something very cool. A friend was buying some stuff on craigslist and the seller offered a discount on further items and forwarded some computer items to me. I got an ATX power supply and a fan, but I also spied THIS. A Triplett 630-NS Volt-Ohm-Milliammeter with the original manual and box!
So twisting the stepper didn’t help a bit. It was already at its maximum and I couldn’t make it go further down the tracks. However at the top there is a small, angular brass plate that functions ...
@nprofile1q... A misalignment of that magnitude would suggest obvious physical damage. Which is guessing you’re not seeing.

@nprofile1q... Oh, how do LEDs look in military electronics?

@nprofile1q... Those are the IR LEDs that shine on the phototransistors. The squiggles next to them are supposed to be the outgoing arrows indicating they emit light.
