Positive I/O Bus Interface

This document serves as the technical documentation and schematics for the Digital Equipment Corporation (DEC) KA8-E Positive I/O Bus Interface. The package includes:

• Master Drawing Lists: Indexing the relevant engineering drawings, test procedures, and accessory lists associated with the module.
• Component Layout: A detailed diagram (M8350) showing the physical placement and identification of integrated circuits, resistors, capacitors, and diodes on the interface board.
• Circuit Schematics: Comprehensive logical diagrams illustrating the gate-level signal flow, bus control logic, and data transmission pathways used for the PDP-8/E and PDP-8/M series computers.

The documentation provides the necessary engineering data for the assembly, maintenance, and verification of the M8350 interface module.
