You should add that it is a real kick when you finally
get
everything right and the sucker actually boots and works!
That's still the best reason to do it. It's a total immersion project
and once done there are few parts of the system that will not be
understood at the software (maybe hardware too) level.
All of my boxes that run CP/M run 2.2 built from the
source
found at the "unofficial CP/M web site":
Some of those I copied to Tim! I was useing them back when
to build mine, from the emergence of V2.2 on.
Da place!
Finding a build environment is left as an exercise for
the reader.
I recommend MyZ80 as a starting point. Then work the hardware
dependent stuff iteritively on the target via serial download.
