It's the Apple combined 64KB RAM/RGB video card for the Apple IIe
auxilliary slot. I knew Video 7 used to make RGB adapters for the IIc,
but I never knew the IIe card sold under Apple's name was made by Video
7 too.
The card ouputs digital RGB video in the Apple III XRGB format. The
connector it's supposed to have will be a 15-pin D socket, wired the
same as the Apple III. It's designed to drive the AppleColor 100 display.
Switches on RGB cards are generally for setting a single foreground and
a single background colour in text mode, instead of just white on black.
The IIGS lets you do the same thing. However this card is unusual in
that it allows for full software control of the text colours. Each
character can have its own foreground and background colours.
Unfortunately this extended text mode never made it to the IIc, IIGS or
other RGB cards, and I don't know of any software that supports it
except for a demonstration disk that originally came with the card. A
disk image is available from one of the Apple II software archives (
sorry, I can't remember which one I saw it on).
