   Unfortunately, this is not correct.  Any *PROPERLY* written software that
runs under CP/M 2.2 will probably operate under 3.0.  Software which breaks
the rules of good CP/M programming practice and make direct BIOS calls, 
however, will probably not work (though some will with the use of a PD
RSX available through the user's group network).  Also, many programs that
manipulate the disk directories may fail, as DRI modified some of the directory
manipulation structures, and also the banking creates a situation where some
of the information on disks & directories which CP/M 2.2 expects to find in
RAM is actuall in a switched-out bank.  Thus, programs that use this information
have to understand about CP/M 3 bank switching.

   Personally, I despise CP/M 2.2, and find CP/M 3.0 marginally acceptable.
As it came with a system purchased for me by an employer to increase my
productivity, I have it.  I probably would not have purchased it myself.
