It's been a while since I indulged in Apple II hacking. I want to pick up where I left off, and that means finishing schematic & layout for an Apple II VGA adapter card. This is a semi-commercial project; "commercial" because I intend to sell it for a profit through my company, and "semi" because the profit will be very small (I do it mostly for the fun...).
I see new forum topics started every now and then on the subject of connecting Apple II to VGA monitors. Some composite-to-VGA converters seem to work, others don't. It would be nice to solve this problem once and for all. There are some alternatives out there, like Carte Blanche, but I would like to build something that is really simple and cheap (BTW anyone knows what the Carte Blanche costs?).
I have a prototype that works pretty good. My biggest concern now is price and volume. So that is why I am asking these questions:
How big is the potential market?
What do you think is a reasonable price for an Apple II VGA adapter card?
