No.

This is NOT because the serial ports are incompatable.  They are still
RS-232C.  THe problem is in the software that directly addresses the
ACIA port.  The GS uses the Zilg? Chip, and that is not quite the same,
hence, when AE Pro or somesuch tries to send stuff directly to the port,
it screws up.  For drivers that use the supplied firmware on the SSC the
GS will work just fine.

>o  The Apple //c WILL NOT BE upgradable with this method.

The //c HAS been upgraded, however.  It has a new motherboard that
allows a 256K-1Meg add on board.  Upgrades for old //c's are available.
The mouse firmware has been moved from "slot" 4 to "slot" 7.  (Shoulda
polled for the mouse.)  The false "AppleTalk not connect" has been
removed (It never worked).  Slot 4 is now the extra RAM, compatable
with the RAMcard that apple has.

This is because they "Phantom" slot.  Phantom slotting can still be done
on the GS, but you have to use the 'IOselect line.

I, too, plan to buy a //GS.  But I'll be hanged if I'll trade in my //e
for it.

Also, I don't know whether the MouseCar will work in it, but I think it
will.  The upgrade does not include one.  I plane to get a 3.5 drive for
my //e and use only 3.5 disks for the //GS.
