I am interested in Z80 CPUs for a long time. Some time ago (it could be about 10 years...) I was working with eZ80. So I was curious if it could run CP/M. It could. So I prepared in C rewritten CP/M with FAT file system support. All BDOS calls are accessing SD card with FAT filesystem. By the time I had Zilog IDE, compiler, USB debugger cable etc.
Now, I want to return to this project. Unfortunately, I don't have these tools anymore. I don't use Windows anymore so Zilog IDE is not the right way for me now as it doesn't work in wine correctly; the only possibility I have found is running command-line compiler & linker to get Intel-HEX output files. Fortunately, Zilog provides description for ZDI interface. I have now all I need to start my work.
