Ok so I bought a nice original Midway Galaga board for my wife.
I'm trying to get all things sorted out, so when I am ready to buy/build I can know what I'm doing. When building my DK machine the worst part was stopping b/c I didn't know how to wire something correctly.
Anyway, coming off the CPU board is a place for a 44-pin edge connector. I am looking over the wiring diagram from the manual but notice there's only going to be 19 wires that connect into the edge connector. I need to know what slot each wire goes into basically.
I'm sorry if these are stupid questions but also, b/c it's a 44-pin connector ( 2 rows of 22) Will I have wires coming from only the top row? If someone has a Galaga machine, a few close up pictures of the wires that come off the edge connector would help, alsso showing which slot each connects to.
One last question. In the manual, everything goes from the CPU board to a Filter Board, and then out to it's final destination. Will I need a filter board? what's it's purpose? I am going to be wiring everything up manually. So I'm using the original board to new power supply, new buttons, new joystick, newish TV (with a RGB to component converter probably).
Any concerns? This is basically what I did with my DK machine but it had a video inverter in addition. I figure it should work for Galaga?
