Can you get a 4.08 MHz accelerator for the Apple (which is what you'd need 
for twice the speed of the C128)?  Last I heard no one's delivering 6502s in
production quantity that are speced to run above 3MHz.

Exactly.  The C128 vs. Apple comparison is very valid.  You'll have to use
Applesoft BASIC (floating point).  This and the C128 BASIC both use the
old Microsoft floating point routines; the operations involved will be just
about identical.  If the BASIC on the PC is Microsoft than the comparison 
is very valid; if you're using BASICA on the PC, its not, for the BASICA
interpreter uses 7 digit floats verses the Microsoft 11 digit floats.
