If you want to modify the BIOS, you need the "CP/M Plus System Guide"
along with a bunch of programs like "gencpm.com" and some .SPR files.
I have my "build" automated using "make", and it simplifies
thing a good bit, but otherwise....

CP/M 3.0 in my case supports bankswitching and (obviously) timestamps.
It is substantially better than 2.2 although things here and there
make you scratch your head.

Anybody have a copy of the banked BDOS source (commented?) ? :-)
