2020 Reviewed

2020 has been another good year for the homebrew retro computer community, but not such a good year for freedom and health!

Example I2C code

I have written some more I2C example code. This code is compatible with SC126 and SC137. More details here.

SC136 Released

SC136 is a simple digital input module designed for RC2014.

SC135 Released

SC135 is a simple digital output module designed for RC2014.

SC133 Released

SC133 is a 12-slot backplane designed for RC2014.

SC134 Released

ZIF sockets

If you want to fit a zero insertion force (ZIF) socket you might like to consider this strategy.

SCM v1.2 Beta

A new version of the Small Computer Monitor (SCM) is now available.

Version 1.2 adds a framework to enable most configurations to be created with simple text files thus reducing the need to manage so many code files. It also makes it easier to add support for new devices, such as serial interfaces. The increased code size required to support these new features means the fully featured monitor does not fit in an 8k ROM.

SCM v1.2 is currently a Beta release and is not yet being used for ‘production’ firmware.

RomWBW v3.0 Released

RomWBW version 3.0 is now available.

SC132 SIO/0 Released

SC132 is a two channel asynchronous serial port module designed for the RC2014 bus.
