OK, I have a clone of the Microsoft CP/M card; no extra memory, uses DMA to
access the system memory, and uses a Mostek Z80.  I am running CP/M 2.2 on a 
64K Apple II+ (heavily upgraded).

My Rana Elite II drive (360K; 40 track, two sided) came with a .com file that
when executed patched the cpm56.com file for sysgenning the new system.  Fine,
no problem, until I tried to upgrade to ZCPR.  The version of ZCPR that I
found uses a submit batch file (and DDT) to patch the cpm56.com file.  The
problem is that both patches are not compatible as written, one will clobber
the other (regardless of which one is applied first).

Further more, I keep toying with the idea of adding a hard drive, but if I
can't properly integrate my Rana drive into ZCPR myself, there is no hope of
adding a hard drive for use by CP/M (most add-on drives for the Apple seem to
be strictly Prodos supported these days).

There must be documentation somewhere on the contents of the system image that
cpm56.com contains and loads onto the disk when you do a sysgen and how to 
patch cpm56.com to make changes!

Any help that anyone can give would be most appreciated!
