>Can ProDOS use the extra 64K of memory as a RAMdisk?

Yes.

If you are in BASIC under ProDOS, the extra 64K bank is called /RAM
and lives in slot 3 drive 2.  It has about 120 blocks of usable space
and can be used like any other drive, except that it goes away when
the machine is turned off.

I believe that the new memory expansion for the //c is the same as the
extended memory card for the //e, which can be expanded to hold up to
a megabyte.  It will automatically configure itself to be a RAMdisk
under ProDOS, Pascal 1.3 and DOS 3.3.  (It is also automatically
recognized by Appleworks to give you an expanded desktop.)  The slot
and drive of the RAMcard are slot 4 drive 1 and the mouse is moved to
slot 7 on the //c with the added memory.

I recommend that you look at the Applied Engineering memory expansion
for the //c also.  It has roughly the same capabilities, except that
you have to run a little program to implement the RAMdisk.  But, it also
has a Z80 chip built-in so that you can run CP/M on your //c.

In either case, buy a card with as little memory as possible because the
discount chip mongors are always cheaper for filling the little holes.
