SCM v1.0 source code and tools:


SCM has the following main features:

  • Boot loader to load Intel HEX files from a PC or similar
  • Memory display and editing
  • Register display and editing
  • In-line disassembler
  • In-line assembler
  • Breakpoint debugging
  • Single step debugging (without the need for special hardware)
  • Extendable using its built-in ROM filing system
  • Supports a range of hardware

Systems limited to 8k byte ROMs are supported, but there is no space for extensions using the Monitor’s ROM filing system. Systems with larger ROMs have versions of the Monitor that include BASIC and a CP/M loader.

The ROM filing system allows additional files to be included in the ROM. These can be programs or help text. These files are automatically integrated into the Monitor, providing an easy way to extend its functionality.

This version fits comfortably in an 8k ROM. This version ships with many RC2014 systems.
