Re: [HRI-devel] here is my little project ...

Hello there

I worked with Z80 assembly, but it was more or less twenty years
ago... there is a project to run unix on Z80 that could provide
pointers (MSX project called UZIX, if I recall correctly), but
you must consider that it has only 64KB address space and it is
slow (3.78MHz, while most SOHO hardware are 75 to 200MHz, RISCs)

to our projects, I plan to borrow some code from cx82100 running
on actiontec modem router, it is almost completely reverse
engeniered (to the ppl who don't follow its list) and could
aid on the difficulties we had in the past (mainly on how to
succesfully cross-compile busybox and stuff like that). keep in
touch!

Cheers
