CP/M

I'd like to find (or build) CP/M for my only S-100 box (you know, the one
with the Ithaca Audio CPU card). I have a BASIC boot disk for the
machine, and I believe I can read/write the 5.25" floppy from my PC
(via 22disk), but I have no idea what's involved in finding or building a
CBIOS for this box and where the boot sector on the floppy is.

I can imagine that this will be a difficult, but not impossible task,
without any documentation for the machine or any of the components, but I
figure I can dump the contents of the monitor ROM and disassemble off-line
to find basic info about serial and floppy I/O. Is there a better way?
