The 1571 supported "
burst mode" loading when used on a C128
in native mode, which increased the transfer speed from 1541
speed to about three kilobytes per second (about a 10-fold
increase). The 1571 could be told to emulate a
1541 for use
with a
C64 or 1541 disks.
Bugs in early releases of the 1571
ROM affected access to
the second side of the disk.
