Ferdinand Meyer-Hermann is very close to releasing his new Apple][VGA card for Apple II, II Plus and //e. The Apple][VGA interface is designed to display crisp text and images, with accurate color rendition on modern LCD monitors. The card does not support any IIGS video modes.
The price is expected to be between $150 and $200 USD plus shipping depending on interest. Contact Ferdinand for details.
Update: ReactiveMicro has made arrangements to demo the Apple][VGA at KansasFest 2008.
