The subdirectory 'm80' contains a Makefile for build using M80/L80 and a CP/M emulator "vcpm". See https://github.com/durgadas311/cpnet-z80 for more information on obtaining and setting up "vcpm".

Currently, the only build targets are:

The plan is to add more as needed.

This build environment aims to avoid the need to manually edit cpxtyp.asm for each build performed. The consequences of that are 'sed' scripts to modify the variables in cpxtyp.asm for each target.

This "vcpm" setup requires that M80.COM and L80.COM be present on the A: drive (directory). Those should be easily obtained from various sources on the internet.

To build targets, "cd" to the 'm80' subdirectory and run "make target". Because the building is done using CP/M commands, errors cannot be detected automatically. You will need to examine the output to ensure all went well.

Bugfixes are also being applied as they are found.

Building requires the 'vcpm', with M80, and 'unix2dos' commands.

'unix2dos' is normally part of the "dos2unix" package on most Linux distributions.

'vcpm' is obtained and setup as described in https://github.com/durgadas311/cpnet-z80. M80 (MicroSoft MACRO-80 Assembler and Linker) is required to be installed in the virtual A: drive of 'vcpm' (rather, one of the drives configured in the search path). One source for this package is https://www.cpm80.com/.
