Thanks for the links...
The reason for not using generic CP/M OS calls is that I use 64HDD as the
fourth drive on my system and to attach a new disk to it I need to do the
equivalent of:
open 15,11,15,"$...path../newdisk.d64" : close
And it seem that the only way to do this is to not use the CP/M service
calls, but to switch from z80 CP/M mode to 8502 mode... Then do the disk
stuff in that mode and return to z80 CP/M when done... But this is all
nice in theory, but I haven't got a clue as to how to do it!

Why do you want to do that? CP/M does all the necessary disk handling.
Just use generic CP/M OS calls.
