A znáte tohle ? z88dk

http://www.z88dk.org/forum/

z88dk is a z80 C cross compiler supplied with an assembler/linker and a set of
 libraries implementing the C standard library for a number of different z80
based machines. The name z88dk originates from the time when the project was
founded and targetted only the Cambridge z88 portable. 

Zkoušel jste to někdo ? (ať už s Z88, ZX nebo Sharpem ?)

díky za info
