PDP-8/E and PDP-8/M

This document provides an introductory overview of the Digital Equipment Corporation's PDP-8/E and PDP-8/M computer systems. It covers the following key areas:

• PDP-8/E Basic System: Details the processor's architecture, including its 12-bit fixed word length, parallel-transfer capability, and memory cycle times. It describes the programming interface, mathematical performance, and peripheral support.
• PDP-8/M OEM Processor: Introduces the OEM version, noting its functional similarity to the PDP-8/E. It lists basic components like the KK8-E processor, MM8-E memory, and OMNIBUS structure, and highlights differences in front panel configurations.
• Computer Organization: Explains how the system components, including the central processor and core memory, communicate via the common 'OMNIBUS' bus. It also describes standard I/O equipment, such as the Teletype Model 33 ASR, and lists the basic FLIP-CHIP module composition.
