PDP-8/E Options

This document, Chapter 7 of the PDP-8/E handbook, outlines various hardware expansion options available for the PDP-8/E computer. It is categorized into four main sections:

• Mechanical Expansion Options: Details on system expander boxes (BA8-AA, BA8-AB, BE8-A) and front panel configurations (KC8-EC, KC8-EB).
• Computer Internal Options: Covers internal components such as arithmetic, memory, real-time clocks, and power fail detection.
• OMNIBUS I/O Options: Lists peripheral controllers and equipment including teleprinters, tape readers, displays, and analog peripherals.
• External Bus I/O Options: Describes external hardware interfaces for storage, data acquisition, and communication.

The document includes detailed block diagrams illustrating how these various options integrate with the OMNIBUS and external I/O buses.
