Pdp-8/I Options

This document is a technical manual titled "Training Drawings, Volume II" for the Digital Equipment Corporation PDP-8/I computer options. It serves as a comprehensive collection of engineering schematics and timing diagrams for various hardware components and peripherals.

The document covers the following key systems and functions:

• Extended Arithmetic Element (EAE): Includes flow diagrams, control logic, and multiplier quotient/step counter schematics.
• Real Time Clock (KW8I): Provides configuration options, clock control logic, and clock counters.
• Memory Systems: Includes memory extension control, inhibit drivers, X and Y axis selection logic, and memory parity options.
• Peripherals: Contains detailed logic diagrams for the High Speed Punch (PC8I), High Speed Reader (PR8I), Display Control (VC8I), Plotter Control (VP8I), and Solid State DECTape (TU55).
• Disk Systems: Provides comprehensive technical documentation for the disk system, including disk control, expander units, disk memory addressing, head diode switch matrixes, and disk timing diagrams.

The manual is intended for technical training and maintenance, providing the necessary logic and timing information to understand the operation and troubleshooting of these specific PDP-8/I hardware options.
