The C128 has built-in code to read and write Kaypro II, Kaypro IV,
Osborne Double Density, and some kind of IBM format.  The limit on
this, however, is only the software.  I believe there is at least one
public domain program out there that will set the 1571 drive up for many
different formats.  The 1571 drive has a programmable MFM controller that
can read most of the CP/M formats that have been used once it is properly
set up.  As for software compatibility, the C128 is most compatible with
a Kaypro.  This is basically screen driver compatibiliy, as I've found most
CP/M stuff to be very transportable (Epson stuff is often an exception to
this; they do quite a bit of machine specific things).  The C128 screen
driver is an ADM-31 (or ADM-3A) with a few extensions for color.  Some 
Kaypro machines have a few non-compatible extensions to the ADM standard,
though the latest versions of the C128 BIOS (December '85 or later) are
a bit more Kaypro compatible than the early C128 BIOS was.
