Martijn> Any ideas?

100% code compatibility, and a 4x speedup at the same clock frequency
sounds nice. I can't seem to find any package information, and the
only picture of the eZ80 is a 100-ish pin SMD. If someone was to make
a small adapter board it should plug right in.

Btw, is there a way of going straight to CP/M mode on a C128? The 8502
in mine is toasted :/
