Yes! I've been reading the replies and finally someone got it! The C128
came with 2 processors, an 8502 (6502 compatable) as well as a Z80 used
for running CP/M. This processor is an add-on for the C64 only, and is
built into every C128.

Well, I don't think it's that far off, the origional comment I made was
regarding porting ELKs to Z80 machines. I was pointing out that there
are a few different machines out there with Z80 CPUs and 128k of ram,
bankswitched using their own scheme, and the C128 was one example I
mentioned.

I've seen a little about it too, it may prove useful elks ideas.
