The aim of this design is to provide a low-cost CP/M system. It uses the Z180 CPU for good performance and RomWBW firmware for robust implementation of CP/M with support for a wide range of hardware.
As a single board computer, it is able to run a wide range of CP/M software without any expansion cards fitted.
The kit comprises parts to build a Single Board Computer with these main features:
RomWBW is a robust ROM-based operating system for retro computers. It includes CP/M 2.2 and Z-System and supports a wide range of hardware, including SD cards and Compact Flash cards for storage. RomWBW has been provided free of charge by its author Wayne Warthen. Thank you, Wayne, for providing this and all the support.
Expansion is available using the two 40-pin sockets. One is mounted horizontally to allow an extension backplane to be fitted, such as SC113.
The kit includes a micro SD card adapter to connect to the SPI port. RomWBW supports SD cards for CP/M and Z-System file storage.
The kit also includes an FTDI style serial adapter and USB lead to connect one of the motherboard's serial ports to a computer running a terminal emulation program.
The kit contains everything you need to build the computer, except a micro SD card, solder, tools and cleaning materials.
The documentation can be found at www.scc.me.uk
The bare PCB is available here on Tindie.
The assembled kit is approximately 10cm (4") x 10cm (4") x 6cm (2.5"). It is supplied in a box approximately 12cm (5") x 16cm (6.5") x 2.5cm (1") weighing about 150g (0.35lbs).
