Actually there was an upgrade to the C64 called the Mach 5 which
was a cartridge you put in the cart slot on the machine which gave
the disk I/O a 500% boost. I understand that the boost you achieve
is actually by boosting the baud rate of the serial port. Commodore
was conservative and didn't use a high baud rate for the floppy drive
and most of the ROM enhancers just changed the baud rate to
a higher value.
