[flashback2 mod. rev c help]

Yours sounds like a Rev. B, or maybe Rev. C is similar. I posted a while ago about my Rev. B board mod with pictures.

 

Anyway, you need to short J3 and open J9, and J9 is actually a 0 ohm resistor that you need to remove, or solder on wires for a switch.

 

The cart pin pads are indicated by a combination of numbers and a white circle in silkscreen around the pad. I agree that #21 is confusing, but if you just look at pads with silkscreen around them, there is only one pad it could be (it's not right by the number, but use the process of elimination to figure it out.)

 

Thanks for getting back.I found #21, after correcting my pinout problem at the cartrige side.pin 1 is bottom right corner thru 12, going left.I had wired the bottom row left to right!I didn't refer to the pinout in the FAQ.thanks everything is working.

Why the 0 ohm resistor? do I need this with the switch mod?

thanks again-"e"
