Very cool. I Googled a bit for a setup disk and (digitized) manual, but have come up dry. Anybody?
I think you'll find that the card is quite easy to use from assembly language (or even Applesoft if speed doesn't matter). The A/D converter and the D/A converter are both mapped to addresses in the Device Select space for the slot the card is installed in. The documentation you'll want is for the A/D converter chip. Almost any application will require custom code, so the disk should be viewed primarily as examples.

I used to have a book about interfacing with it (and the joystick port), but it's long gone....It can be used to capture and log analog data and to produce a programmable voltage. You could use it to simulate a strip chart recorder with your Apple II. I forget how fast the A/D converter is, but it's probably fast enough to sample sound (11kHz) in a suitable loop.
