Apple Modem 300/1200 Serial Cable Pinout
Posted by: Zhinü on 2023-05-16 18:02:24
I’ve got one of those Macintosh 128K/Apple II/Lisa Apple Modem 1200s, but one thing that my modem didn’t come with was the DE-9 to DE-9 cable for the Macintosh 128K. I‘ve searched around but can’t seem to figure out the pinout to connect them together. Does anyone here have a cable that they can pull the pinout from?

Using the labels on the DE-9, this is what I got for the pinout.
