I'm trying to convert my Model F AT to USB and remap for ANSI. I got the Pro Micro and using the diagram here
https://deskthority.net/workshop-f7/how-to-use-a-pro-micro-as-a-cheap-controller-converter-like-soarer-s-t8448.html I soldered 4 wires to it in the correct spots.
I tried to figure out which pins but I think I messed up. I already took the 5 pin connector off the end of the cord that goes into the board. So the serial connector just goes to 5 separate connectors.
And I've actually cut them off so right now the serial goes to nothing.
The Pro Micro has 4 wires soldered to it, GRD, 5v, data and clock.
I can't find anywhere that says what 4 pins on the keyboards 30 or however many, should be used.
Anyone know?
