Small Computer Monitor

The Small Computer Monitor (SCM) is a classic machine code monitor for Z80 based systems.

There are two current versions:

  • Version 1.0 is still the current version for most hardware.
  • Version 1.1 cleans up the interface between the monitor and the BIOS sections, making it easier to add new hardware support. Only a few of the configurations of SCM have currently been ported to this code base.
