The lack of specific support does not exclude the use of other hardware. It just means the ROM does not do anything specific with it.

Supported Modules

• Processor and memory:
  • SC111, Z180 Processor module

• Memory:
  • SC119, Z180 Memory module
  • Marten’s Z180 Linear Memory Module (not tested)

• Serial port:
  • SC111, Z180 Processor module

• Timer:
  • SC111, Z180 Processor module

• Baud rate generation:
  • SC111, Z180 Processor module

• CP/M storage:
  • SC145, compact flash module
  • RC2014, compact flash module
  • Karl’s #10d, compact flash module (not tested)
  • Karl’s #10e compact flash module (not tested)

• Self-test status display:
  • not applicable

The lack of specific support does not exclude the use of other hardware. It just means the ROM does not do anything specific with it.
