System Introduction

Summary

This document provides an introductory overview of the PDP-8/E and PDP-8/M computer systems. It details the architecture, technical specifications, and general operation of these machines.

Key highlights include:

• PDP-8/E Overview: Designed as a compact, general-purpose, 12-bit, parallel-transfer computer. It utilizes a 4096-word magnetic core memory and is built for modular expansion to meet diverse user requirements.
• Performance: The system features a 1.2/1.4 microsecond cycle time, supporting rapid arithmetic operations, including 385,000 additions per second.
• PDP-8/M OEM Processor: This is a functionally identical version of the PDP-8/E, marketed as an Original Equipment Manufacturer (OEM) model. It uses the same processor, memory, and OMNIBUS architecture, with minor differences in physical configuration and operator panel options.
• System Organization: Both systems are organized around the "OMNIBUS," a central bus that facilitates communication between the central processor, core memory, and various input/output peripherals. Standard peripherals include a Teletype Model 33 ASR, though the system supports a wide array of options ranging from card readers to high-capacity disk storage.
