Atari Realtime Clock Driver    

Extensible driver system for real time clock upgrades.

Support

This driver works with the following types
as well as similar ROM based clocks:

  DS1216E       DS1216F       DS1315  

It should also work seamlessly with any TOS and Atari
applications for setting date / time, such as XControl.

⚠  Caution  ⚠

Using other clock drivers, y2k fixes or 3rd party Dallas
applications for setting time may cause problems.

Most problematic are ones that rely on the IKBD
which compensates by modifying the set year.
