I had already made a video on how to access a current time and date source from my RTC module for the Commodore 64.

Here I am demonstrating how to access the 4kB memory expansion embedded in the above mentioned RTC module.

The demo application actually also writes to the EEPROM, which is how the 2 messages shown in the video were written to it!

Possible applications? Store there your favourite hi-score tables :)
