Color Classic G1 pin locations?
Posted by: Outlander on 2017-04-01 16:16:12
Got a Color Classic logic board here that has a bad thru hole connection. Looks like someone did a nasty job at trying to clock chip it (can't be done this easily on a CC) and reamed one of the holes out. Does anyone know where the 4 pins at G1 go to? Thanks!

Pin 1 usually is N/C so you should be ok.

One pin is connected right to that big ground plane, another one goes straight to that one big IC right next. Looks like the trace is broken in your picture so you might have jump that one with a wire.

The remaining pin goes to +5V.
