The VPP (12V programming voltage) pin is not on the cart slot, but it could be if you like (use some unused pin). I used a wire for that. I'm working on EPROM stuff as all EPROMs are not programmed the same way. There are lots of Flashes out there, if its industry standard and 5V it can be used with...
