I have moved my CP/M 3 to
https://gitlab.com/SolderGirl/CPM3_2063_Retro
I have also revamped the build process to use MAKE.
If you have a 2063 Z80 Retro! board with the official CP/M release, you can just download the .LBR file, transfer it to your CP/M, then unpack it on a separate drive or user area, and just run MAKE. With no options, it builds everything.
