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 version 3.0 is now available.
Important points to note about v3.0:
- The default baud rate for SCxxx products is now 115200.
- Drive letter assignment is different to earlier releases
Full details, source code, and documentation is available on GitHub.
ROM images for SCxxx products can be found here:
Upgrade instructions can be found here.
This is a very significant milestone for RomWBW. Well done Wayne.
RomWBW v3.0 will be included in new SC131, 130, 126, and 119 kits as soon as the current stock is exhausted.
