Hi everyone,
I recently bought a jap. Space Invaders Part II Table with a Moon Cresta PCB in it.
Everything is working fine but I wanted to replace the Moon Cresta with a Space Invaders Part II PCB so the table would be original again.
I only found a Space Invaders I PCB and bought it. I am currently waiting for it to arrive and in the meantime I was wondering how to get the B+W video signal for pin 18 on the CPU/Rom board? Can I simply pinch together RGB + SYNC and wire it to pin 18? Are there any other modifications I have to make because of the color monitor or is it Ok since I can wire RGB to the sound board?
Here is the pinout i found:
