Hi folks,

I got an A2 Pi Pico card that doubles as a VGA card or a CP/M card.

I understand this project is open, so there is more than one developer working on it.

My problem is that my card won't handle double high-res as it should… A2Desktop looks awful. If I set the card to B&W, then it displays properly.

My question: what is the best firmware for the VGA function to use with a //e?

Thanks.

Sorry if I misunderstood your point, but if you are mentioning double heres mode, the output will not be correct unless pins 50 and 55 of the expansion RAM card are connected. Check them out.
*In the case of a genuine apple 64K card, this is the AX1 solder pad.
