~This is the original SMD version of the board, which is not as easy to hand solder; therefore they can be used for wave-soldering or a solder heat gun. Hand Solder SMD Version, Through Hole Version.~
A take on Helder’s own MD2 composite video fix, only using the onboard clock signal fed on R61 instead of using a separate crystal oscillator. Composite video clock fix for Model 2 Sega Genesis consoles for the following:
Motherboards with VA0, VA1, VA1.8 revision
Samsung KA2195D video encoder
Instructions: Twitter thread for now.
Notes:
This particular PCB uses Imperial 1206 size SMD components.
Removal of the original 10K resistor on R61 is required.
R61_L is +2.5V as VREF, connecting to SBCR.
R61_R is GND, connecting to C24, then KA2195 pin 6.
