A community project between exxos, Thibaut Guillet, Jonathan Whiteside , and Troed Sangberg.
A simple internal RTC module was created to add a time and date clock to the ST without needing a cartridge. The design is based on the "forget me not clock" and is wired internally in "pass through" mode so it does not conflict with any cartridges which may be used on the cartridge port.
