Notes

1. Tie all the GNDs together and run to a GND. The others run straight to the PCB.
2. This monitor uses composite sync. You will need to construct a circuit to convert the CoCo 3’s separate positive sync signals into a negative composite sync, or you can try using the composite video output as your sync signal. If you have trouble getting the monitor to sync, try running a 47ohm resistor from sync to ground on your adaptor.
3. Run the color leads through 220uf capacitors, or else you get SILLY color bleed on many games.
4. Cracked solder joints on the flyback were a chronic problem on the //gs monitor.
