The module has the following features:

• Three clock sources selected with jumpers
• Wide range of frequencies from 600 Hz to 7.3728 MHz
• Baud rate clock typically from 9 to 115200 baud
• Compatible with RCBus and RC2014 bus

Each of the three clock sources can be set from a wide range of frequencies and can be connected to any of four possible pins on the RCBus. This enables the CPU clock speed to be configured and baud rate clocks to be supplied to serial modules.

Compatibility

This module conforms to the RCBus specification v1.0 and thus supports: RCBus-2014, RCBus-Z80, RCBus-68xx, RCBus-9995.

The RCBus specification includes RCBus-2014 (both RC2014 standard 40-pin bus and RC2014 enhanced 60-pin bus) and also the full 80-pin RCBus. The 80-pin RCBus provides support for advanced Z80 features, such as the interrupt daisy-chain, as well as support for other processor families.

The Kit

The full kit includes all the components needed to make the module, as shown in the first picture. Other modules and backplanes shown in the other pictures are not included. You will require tools, solder and cleaning materials to assemble this kit.

Printed Circuit Board
