	They need not drop 1541 compatabilty to achive really good proformance
from the internal drive.  The trick is to include a logical 1750 and 1581,
then have the drives memory as a DMA bank.  The cpu banks are the same as
DMA banks, but the REU chip is faster.  Or system cost could be kept down
by using just one cpu and no REU chip, but then the internal drive would
not be useable in C64 mode .
