stdio functions via the CPUville monitor

This post covers replacing the standard crt0.rel file and making stdio work with the CPUville monitor.

Using SDCC with the CPUville system

As much fun as assembly coding is, sometimes (most times) I want to be lazy and use C.

SDCC knows how to emit Z80 code so that looked like a good place to start. It is easy to download and install and until you start trying to tell the linker how to lay memory out it is pretty easy to use too.
