Now I'm confused (nothing hew here). If I use the switcher set to 5V, the board will see less than 4 after the voltage drop across the diodes. If I crank up the switcher to something like 7VDC to see 5VDC at the board, I won't be able to use the same switching power supply on the Gallag board, used in the 2-1 JAMMA switcher. Right?
SirPeale:
That's correct. Sorry, I didn't realize you were swapping boards. What I described is only for the Galaxian.

And waste precious energy ! ;) Mod the Galaxian board, it's only two little wires, it's not like hacking it all up....
And you can keep the PS at 5V for the Galag board....
Neverending Project:
Does anyone know the "Speaker -" pin for the Gallag board? I am looking at the pinout here and it is not listed.
Also, is there a DIP setting list somewhere? Anyone know how to set free play?
Thanks.
Neverending Project:
I found info on the pinout here. I will try this, but it looks like no Free play. Now on to the speaker wire...
