Before I plug this in, I need to inspect the machine to ensure it won’t be damaged or gummed up as it begins to operate. A helpful person that sells parts for these machines recommended simple green as a gentle degreaser, followed with lubricating according to the manual. Manuals can be found at Teletype Corp. Maintenance, Installation, Operation, and Parts Publications (navy-radio.com) although getting familiar with the terminology will take a bit
This machine is gummy and dusty, but as far as I can tell there is no mechanical damage or electrical burns on it. Wires all appear intact. The primary motor that gets everything moving spins freely and moves the internals around quite a bit in what I think is correct operation.
Looking at the manual, it appears that there were two paper feed mechanisms, and I have the ‘sprocket feed’ type. Modern term seems to be ‘continuous form’ paper, which if the dimensions are the same, appears to be readily available. Its been decades since I have seen this type of paper though. The sprockets are a fascinating mechanism, the teeth retract as they rotate to only be out when needed to pull paper, and retract when they would get in the way of the mechanism. It appears to be working smoothly.
I will have quite a bit of cleaning ahead of me as there are many places gummy residue is hiding, but I am fairly optimistic that this is in good shape and will be either working or repairable.
Ill have to interpret what connections 5 and 15 are and that should move me towards understanding the input output of this device. Using some sort of serial connection isn’t possible directly, it requires a fairly stout (likely 60ma) current to drive it.
