Printed Circuit Board

PCB dimensions: 4.0″ x 4.0″ (101.6mm x 101.6mm) = RCBus 80-pin “large” size module

User Guide

The illustration below shows the connections built into the PCB. These are designed to allow both narrow and wide dual-in-line ICs and also 0.1″ pitch connectors on the back (right) edge of the module.

Assembly Guide

Below is the suggested order of assembly. A general guide to assembling circuit boards can be found here.

  1. Bus header P1
    Make sure the pins are parallel to the PCB so that the board is vertical when it is fitted into a backplane socket
  2. Fit the nylon spacers in the mounting holes

Compatibility

This module conforms fully 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 table below indicates electrical compatibility with each backplane type (40, 60 and 80 pin)
