This page describes some of the options for complete systems based on the SC108, Z80 Processor module.
Option A : Two Module SCM System
This two module system runs the Small Computer Monitor, which includes BASIC. It has no storage, but is adequate to write small machine code and BASIC programs.
- SC108, Z80 Processor Module
- SC110, Z80 Serial Module with baud rate control
- Backplane, such as:
Recommended firmware: Small Computer Monitor S3
Option B: Two Module CP/M System
Using Karl’s combined serial and compact flash module, a capable two module system can be built to run CP/M.
- SC108, Z80 Processor Module
- Karl’s #61 Serial I/O and Storage (CF) Module
- Backplane, such as:
Recommended firmware: Small Computer Monitor S3
Recommended software: Standard RC2014 CP/M for ACIA
Option C: Three Module CP/M System
This CP/M system is built from three modules and offers software control of the second serial port’s baud rate.
- SC108, Z80 Processor Module
- RC2014, Compact Flash Module
- SC110, Z80 Serial Module with baud rate control
- Backplane, such as:
Recommended firmware: Small Computer Monitor S3
Recommended software: Standard RC2014 CP/M for SIO
Option D: Three Module CP/M System
This CP/M system uses SC108 to replace some of the modules in the RC2014 Pro kit.
- SC108, Z80 Processor Module
- RC2014, Compact Flash Module
- RC2014, Serial Module
- Backplane, such as:
Recommended firmware: Small Computer Monitor S3
Recommended software: Standard RC2014 CP/M for SIO
