#real-time clock

After my fun with real-time clock chips (here and here) I figured it was time to add one to the Zolatron 64. But there was a catch. The previous experiments had involved microcontrollers with built-in SPI capabilities. That was something the Zolatron sadly lacked. Luckily, someone else has already come up with a solution. The 65SPI project by Daryl Rictor is a very easy way to add an SPI…
