Subject: CPM upgrades, etc.

Phillip Keen asked for opinions on CPM3.  Here's my two cents:
I first learned CPM on a CPM3 system.  I found it very clumsy.  I then 
at the suggestion of several folks 'downgraded' to CPM 2.2.  CPM2.2
is, to my mind, far more straightforward to use, and definitely a lot
easier to program for than cpm3.  I rewrote, er, adapted, the BIOS from
the CPM3 into the CPM2.2 BIOS that I now use.  I then a short time later,
at the suggestion of the same people, installed ZCPR3 from Echelon.
It was a straightforward procedure underCPM2.2. It was impossible under
CPM3. Oh, and I have found compatibility problems between 2.2 and 3.
Bottom line:  If one is going to use another CCP (highly recommended),
use your cpm2.2.  I strongly recommend ZCPR3, but there are others.
I would not even waste my time with CPM3 even if they gave away free
food with it.

Hope this helps.  E-mail me if I can be of further assistance.
