Hi

Yes there�s some z80 code in there, but I don�t belive it will compile with
zcc. (maybe the arch/z80/* part)
I�m playing around with zcc 0.96

There�s much code you�ll never need. It� a question of the target.
On x86 side, you�ve got all you need .. Floppy, HD, CRT Controller, BIOS etc.
On z80 you can assume, there is nothing. Sometimes there is a BIOS which tries
to boot CPM from a disk (e.g. C128, Robotron (old GDR computer with a ripped
CPM) or Apple), but mostly there is a Basic (which is no use of .. well may be
with a boot loader from tape and a RAM disk, if it�s expansioned)
Best of all put it in ROM.
It�s not as easy as on x86.
>At least this is how I envisioned doing such a project.
Well my visions are : searching for a capable compiler, playing around with
some code until something works or the memory runs off (that�s the time to
look for a expansion, maybe Tim�s seems nice)
The main question is the compiler �cause zcc�s got even problems with 0.0.12�s
printk.c (typedefs unsigneds, voids)
