You're basically correct in your description of the 80-column memory scheme,
however the second 40-column bank doesn't reside at $800-$bff as stated.
This would have been nice, but would have made the Apple IIe incompatible with
Applesoft BASIC from the Apple II+ since Applesoft starts your programs at
$800.  A lot of other non-BASIC software would also be incompatible.

Your reference to the "extra bank" from the extended RAM card is more on the
money -- however, the card need not be the "extended RAM" type.  The original
Apple IIe AUX slot card was only for providing the extra 40-column bank -- no
other memory was provided.

Lastly, your comments about screen holes are perfect.  And a floppy drive will
indeed make some raspy sounds if you screw with just the right screen holes.

(Didn't want to pick your message apart, but just wanted to make sure nobody
got confused with the $800-$bff part).
