This repository contains scripts, tools and source needed to build a Commodore 128 CP/M system disk.

You're viewing the master branch, which contains Kerberos SRAM expansion support, plus fixes and speedups for 80 column mode from the cpmfast release by Linards Ticmanis.

Currently only CPM+.SYS is built from source, while the rest of the binaries are taken from the updated cpmfast release.

$ ./build-osx.sh

If everything goes well, a new image cpm+128.d71 is created.

It's possible to use the Windows Subsystem for Linux to build. Tested with Ubuntu on Windows 10, you'll need the following packages

$ apt-get install build-essential libreadline-dev libncurses-dev unzip

Then just run

$ ./build-unix.sh
