This card adds a real-time clock/calendar and an I2C bus master to the Z50Bus.

The main features are:

• Z50Bus card measuring approximately 100mm x 75mm (4″ x 3″)
• Real-time clock (RTC) using DS1302+ integrated circuit
• I2C bus master for 5-volt I2C devices
• Configurable I/O address with tight address decoding
• LED indicators to show the state of the I2C signals
• A variety of I2C bus connections (both male and female)
• Spare I/O lines available via header pins
• Jumpers to allow I2C signals to use the bus USER pins

The I2C bus is compatible with many 5-volt I2C devices, including the SC400 range of I2C modules.

The real-time clock is supported by RomWBW firmware. RomWBW runs on SC140 Z180 processor card for Z50Bus.

Accessories, such as cables, can be found here.

The kit contains everything you need to build this Z50Bus card, except a CR2032 battery, solder, tools, and cleaning materials.
