Title: Need PBC Pinout For IBM PC AT
Post by: jevvix on Fri, 05 September 2014, 18:44:29

I bought an IBM PC AT without the entire cable. Does anyone happen to know the pinout from the PCB? I believe 4 of the the 5 pins on the far right are the ones I need (+, -, data, clock) but I'm not sure which are which. Any help appreciated!

I put some documentation on the pinout in my thread.

I put a Soarer on mine recently and still have the paper around ... here it is:


When you look at the pins for the cable, here's what you see (they are the pins on the border of the bcp, look for the missing one as a reference):


*   *   *
*        *


Use the "empty" pin as a reference and here's where they go:


Top left is Data
Top middle is Ground
Top right is Clock
Bottom left is Vcc
Bottom right is nothing


Enjoy!
