I have a model 43 teletype which someone previously pulled the Terminal Auxiliary Unit (the thing that converts the line in to CMOS digital levels) and kludged in a current loop adapter. I want to add support for both current loop and serial again but while I can find the diagrams for the board they list the components with Teletype part numbers. Does anyone have a cross reference or will I need to do a bit of reverse engineering of their numbering?
474032 - 74LS32 - Quad 2-input OR gate?
474008 - 74LS08 - Quad 2-input AND gate?
