Digital Research CP/M Releases

Builds of CP/M based on the open source release of Digital Research code. See the licence at www.cpm.z80.de for terms and conditions.

These contain source code and scripts to allow cross-compilation on Unix-like systems. To build, you will require:

From www.cpm.z80.de: The PL/M 4.0 compiler (found in plm80.zip) to build CP/M 3. To build CP/M 2 you may want to downgrade to the PL/M 3.1 compiler (found in plm80x86.zip).
Thames to run the PL/M compiler and build tools.
ZXCC to run CP/M-hosted build tools.
