Part 2

This document serves as an overview of the various options and peripheral equipment available for the PDP-8/E computer system. The content is organized into four main sections:

• Mechanical Expansion Options: Details system expander boxes (BA8-AA, BA8-AB, and BE8-A) and front panel configurations (KC8-EC and KC8-EB).
• Computer Internal Options: Covers core internal components such as extended arithmetic elements, memory equipment, real-time clocks, and power fail detection.
• OMNIBUS I/O Equipment Options: Describes standard peripherals connected directly to the OMNIBUS, including teleprinters, paper tape readers, plotters, card readers, magnetic tape units, and laboratory peripherals like A-to-D converters.
• External Bus I/O Equipment Options: Details equipment interfaced via the external bus, including disk storage, advanced data acquisition systems, and specialized communication interfaces.

The document also provides comprehensive block diagrams (pages 7-2 and 7-3) illustrating how these various modules and peripherals integrate into the broader PDP-8/E system architecture.
