Rx8-e Omnibus Interface

This document is a technical schematic set for the DEC (Digital Equipment Corporation) RX8-E Omnibus Interface, a controller module used for interfacing peripherals with the computer bus.

• Page 1 provides a physical layout of the printed circuit board, showing the placement of integrated circuits (ICs), resistors, and capacitors. It also includes a comprehensive Parts List detailing the components used on the board.
• Page 2 details the logic schematic for the Device Select, IOT Decode, and RXOI Control logic. This section manages bus communication signals, interrupt requests, and state control for the interface.
• Page 3 provides the logic schematic for the Transfer Register and RXOI Control, focusing on the data flow, bit manipulation, and parity generation/checking required for data transfers across the Omnibus.
