Hello all together! At the moment i try to bring back a TTY from Teleprint to life. It is a TP-3328. A labeled Teletype ASR33. It looks like the original ASR 33. Differences are the missing off position on the on/off/local switch. The Motor of the ASR starts up at every key touch and stops after a letter ist printed. The Elektronic part at the right is also different. My problem is the current loop connection. The molex plug no. 2 and the terminal strip below did not exist in my tty like in the original ASR manuals described. Has any one information about the TTY`s current loop interface?
