Except that the extra PC trace needed for this was never run to
the rom socket.  :-(  The decoding is in place, however.

I hope C= goes to a 512K ROM anyway, it's obvious the space could be
well used.

While I'm picking nits, here are two more:

The A501's real time clock cannot be easily calibrated.  The
case is soldered shut and there is no access hole to the 
trimmer capacitor.

The right hand side of the A500's keyboard needs another support.
And the A2000's keyboard needs to learn some tricks from the A500 :-).

Somehow I think the root of Mike's complaint is simply that 
Commodore did not offer a way for Zorro I and SOTS cards to
be added to an A2000.  The rest grew out of that.  He seemed
to calm down a bit after I offered to build some adaptors
for him. :-)
