I'd like to build a cable to connect the RS-232 board on a TRS-80 Model I to a standard DB-25 RS-232 connector. Does anyone know the pinouts of the 40-pin RS-232 edge connector on the Model I expansion interface? If so, please send me a message with the details and I'll summarize to the net in the unlikely event that someone else wants to know.
