Clockwork64 is an extremely exact (±1 minute/year) real time clock for Commodore 64 which connects to the userport. Finally you can make that port actually useful!
The RTC is based on a Maxim DS3231 which is connected to a microcontroller that reads and displays the time on the LED segments.
Clockwork64 has 5 different modes that can be switch by pressing a button: Time (HH:MM:SS) → Date (YY:MM:DD) → Timer (up to 99 hours) → WOPR launch code* (a tribute to the movie War Games) → Stealth (just three dots). The last selected mode is saved and starts after a power cycle.
*Check out my expansion port board WOPR64 if you haven't already!
This product was inspired by Timo Voutilainens project connecting a RTC chip to the C64: Timos project website. Here you can also download the software (D64 image on the bottom of the page) that sets and reads the time/date from the RTC chip. You can even fetch the time to the TI$ BASIC variable.
The board also has a battery holder for a CR2032 lithium cell (included) that keeps the time and date when the board is not powered by your C64. All boards are tested after assembly.
