Information on this card can be found here: http://www.applelogic.org/files/AppleIIVideoOverlayCard.pdf
I'm interested in finding an Apple II Overlay card because it contains a duplicate of the IIGS display hardware, and everything the IIGS hardware can do can be taken advantage of on that card in addition to the onboard IIGS display hardware. Mostly I'd like to buy one to try and see what I can hack up code-wise to play with that.
Thanks
