This page describes some of the options for complete systems based on the SC111, Z80 CPU 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.
- SC111, Z180 CPU Module
- SC119, Z180 Memory Module
- Backplane, such as:
Recommended firmware: Small Computer Monitor S5
Option B: Three Module CP/M System
This CP/M system is built from three modules and offers software baud rate control of the both serial ports.
- SC111, Z180 CPU Module
- SC119, Z180 Memory Module
- RC2014, Compact Flash Module
- Backplane, such as:
Recommended firmware: Small Computer Monitor S5
Recommended software: CP/M 2.2 BIOS S5 v1.x
Option C: Five Module CP/M System
This CP/M system uses SC111 to replace the CPU module in the RC2014 Pro kit. In this configuration the Z180’s on-board serial ports are not supported and a 7.3728 MHz oscillator is required on SC111.
This set up uses the Z180 module as just a Z80 CPU replacement, and is limited to a 64k byte memory map as the extra pins needed to support more memory are not present on the Pro backplane.
- SC111, Z180 CPU Module
- RC2014, Pageable ROM Module
- RC2014, 64k RAM Module
- RC2014, Compact Flash Module
- RC2014, Dual Serial Module
- Backplane, such as:
Recommended firmware: Small Computer Monitor S4
Recommended software: CP/M 2.2 for Pro kit
