To install: First save the original files "cpm22.bin" and "DS0N00.DSK" on the Z80-MBC2 microSD card.

Copy new "DS0N00.DSK" to the Z80-MBC2 microSD card. This contains the original Z80-MBC2 files with some ZSDOS files such as "copy.com".
DS0N00 also contains the ZCPR and ZSDOS binaries on "Track 0".
