Small Computer Monitor v1.1

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

Version 1.1 cleans up the interface between the monitor and the BIOS sections. Only a few of the configurations of SCM have currently been ported to this codebase. Other configurations can be found in the SCM v1.0 distribution.

Known Bugs and Limitations

  • Single stepping does not execute instructions that result in the program counter not changing, such as DJNZ when B > 1 and the relative jump is to itself
