Here is a URL to a PDF that explains what you have to do to a stock ASR 33 to make it communicate with a PDP 8 or 11
http://www.pdp8online.co.../CHD/LT33_print_set.pdf I have the wiring from the computer to the terminal strip correct, which is enough to receive from the computer, but not send. From the mate and lock connector Pin 2 --> terminal strip 6 Pin 3 --> terminal strip 3 Pin 5 --> terminal strip 7 Pin 7 --> terminal strip 4 Next I need to connect a reader control circuit, and change some of the terminal connections and control unit wiring per DEC specs in the document linked above. I will have to settle for receive only mode until I can get the rest of the wiring and install a "reader run" circuit. DEC sold a reader run circuit board, part number 4915. I might have one of these lying around..stay tuned. Reply |
