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. 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. Jeff G aka Bags
