I don't think it'll need special software. It goes in slot 7 (only -- it
needs some clock signals that are only on that slot), and may also
connect to one of the aux video connectors on the mainboard. You also
have to do the Eurapple modification (as in the TechRef -- cut and jumper
the pads and change the crystal) unless you have a Europlus.

Argh!!!

The 6522 is a 16 bit parallel chip with all sorts of features
(counter/timer, etc). No idea what this card does -- could it be an
interface for some medical instrument?

Probably a CP/M add-on card. It uses the main Apple memory, of course.
You need to find the CP/M boot disks for it.

Maybe a firmware Applesoft card. This would contain floating point
(Applesoft) BASIC, to be inserted into slot 0 of a machine with Integer
BASIC on the mainboard. The switch selects which BASIC is active after
reset. Personnally, I perfer a 'language card' (RAM) in slot 0, since I
can load BASIC, Pascal, etc from disk.

Some 80 colum cards had an extra little PCB that fitted under one of the
video timing chips on the Apple ][ mainboard, and which carried a cable
to connect to the main 80 column card. Maybe it's for that. Maybe it's a
light pen connector. Maybe it's a video input for sutomatically switching
the monitor between the 80 column card and the Apple's 40 column output.

Sounds like an EPROM programmer. Is there an step-up converter on the
card (any 'wound components'?)

That's a simpler 16 bit parallel I/O chip.

Presumably to select 2716/2732/2764 EPROMs.

Sounds like a user I/O card for hardware hacking type projects. You've
got 32 I/O lines there, presumably brouhgt out the DIL sockets. You
connect those to your own hardware, etc...

_Maybe_ one of those cards to interrupt the Apple after loading a
copy-protected game, etc so you could save an image of memory to disk.

The above are all wid guesses -- I'm not even an Apple ][ person...
