As you suspected, that is the Apple II Memory Expansion Card.  It will
work in an Apple ][, ][+, IIe or IIgs.  (It must be used in a standard
slot for the IIe and IIgs.)

Whatever slot you like, except slot 3 (unless you want to lose 80-column
mode).

The card will act as a RAM disk for ProDOS or Pascal 1.3 without any
special software, and is a bootable device for an enhanced IIe, so you
should probably put in a lower numbered slot than your normal startup
device.

If you want to use it as a RAM disk in Apple II Pascal 1.3, it must be
located in slot 4, 5 or 6.

You can also use it as a RAM disk for DOS 3.3.  I believe it needs to be
"initialized" by using the IN#n command to patch itself into DOS 3.3.

AppleWorks 1.2 (?) and later include a driver for this card, allowing it
to be used as expanded desktop space.  If you have both this card and an
auxiliary slot card like a RamWorks, I can't tell you off-hand which one
will be used first.  (I expect you could patch AppleWorks and/or remove
some of the drivers if you wanted to force a particular card to be used
as expanded desktop.)

Yes.  The opposite isn't necessarily true - the Apple II card may use
slower RAM, which won't work reliably in a IIgs memory expansion card.
