Embedded Resources

This directory contains some binaries which are embedded into the main cpmulator binary, the intention is that these binaries will always appear present upon the local disc. These make use of our custom BIOS functions, making them tied to this emulator and useless without it.

Other CP/M code within the repository includes:

• The top-level dist/ directory contains a complete program used to test the emulator.
• The top-level samples/ directory contains some code which was useful to me to test my understanding, when writing the emulator.

More significant programs are available within the sister-repository:

• https://github.com/skx/cpm-dist

Contents

The embedded resources do not have 100% full functionality, you cannot bundle a game such as ZORK, because not all I/O primitives work upon them, but simple binaries to be executed by the CCP work just fine.

• ccp.z80
  • Change the CCP in-use at runtime.
• comment.z80
  • Source to a program that does nothing, output to "#.COM".
  • This is used to allow "# FOO" to act as a comment inside submit-files.
• console.z80
  • Toggle between ADM-3A and ANSI console output.
• ctrlc.z80
  • By default we reboot the CCP whenever the user presses Ctrl-C twice in a row.
  • Here you can tweak that behaviour to change the number of consecutive Ctrl-Cs that will reboot.
    • Require only a single Ctrl-C (ctrlc 1)
    • Disable the Ctrl-C reboot behaviour entirely (ctrlc 0)
• debug.z80
  • Get/Set the state of the "quick debug" flag.
• test.z80
  • A program that determines whether it is running under cpmulator.
  • If so it shows the version banner.
