GAT Got-Ya pcb pinout?

I have to test a GAT Got-Ya pcb, but I can't find the pinout anywhere. Does anyone know where to find the pinout?
You are going to have to figure it out. It's 's really not that hard. Or, just send it to me. ;*) I've regretted selling mine for a brry long time.
 
These ok?

Step1 - figure out power and grounds.

Based on manual, board takes +5V , +!2V , and -5V. Use volt meter on TTL ICs to find +5V and GND.


Step2 - figure out monitor outputs R/G/B/SYNC/(GND); likely will be in a grouping. In schematic it says card edge is R=30, G=33, B=31.

Then you'll be able to at least "see" it working.


Step3 - figure out the controls etc. Look where there are traces and ohm back to ICs based on schematic.


I don't think this will be too difficult to reverse engineer.
 
It looks as though there's labelling for +12V, +5V, ground, and 'N' (-5V?) on some of the traces. That should help to narrow the field.
