The most important difference is that 1570/1571 uses the same kind of
CIA's as in C64/C128, while all versions of 1540/1541 uses the same
kind of VIA as in the VIC 20 and PETs.

Atleast in theory you might be able to make some kind of adapter board
with some glue logic, and a modified version of the firmware, to use
the 1541 disk hardware with something similar to the 1570/1571 IEC
hardware. But it won't be worth the effort - if you want better speed
then go for JiffyDOS or Dolphin DOS instead.
