FYI, not much need to bother with the circuit boards. The meat of it (the teletype portion) is non-electronic and doesn't really depend on the boards at all. The phone part on the right was a Telex dialer, and it won't work with anything you can find today, short of possibly I-Telex.
Not POTS then? My ASR-33 with Data Set is totally POTS. I tested it by dialing up CompuServe.
If you need help wiring, etc let me know as I have a 32 and can send pics. You'll need a loop supply capable of 60ma, which can even be a 12v supply just to shut it up while testing/running. Without a loop supply it'll chunk non-stop. Usually "proper" teletype loop supplies are around 120V DC though.
I'm restoring a number of Model 15s and Model 19s and a Model 14 for a friend. I'm aware of 120VDC 60mA current loops. The ASR-33 is 20mA @ 12VDC (or so). You are saying that the selector magnet in an ASR-32 pulls 60mA? -ethan
