The C128 runs CP/M 3.0, which uses both banks of memory when normally
operating.  The extra memory allows a larger TPA, and generally results in
a faster machine.  The RAM Expansion module (1700,1750) are configured as
RAMDisks in CP/M, giving you up to 512K of RAM Disk, as drive M:  WordStar
will load in about a second off of drive M:, other things are similarly 
very fast.

   A quote usually goes here, but its currently being rennovated.

       These opinions are my own, though for a small fee they be yours too.
