PDP-12 Hardware Student Guide No. 1 (Adjustments, Diagnostics & Troubleshooting)

This document is a student guide outlining a comprehensive training program for PDP-12 hardware, focusing on adjustments, diagnostics, and troubleshooting. The guide details a series of sixteen laboratory exercises, totaling 32 hours, designed to provide hands-on experience with various aspects of the PDP-12 computer system.

The curriculum covers fundamental operations such as loading different types of program loaders (RIM and Binary), checking memory using diagnostic patterns, and tuning memory. It progresses to detailed hardware diagnostics, including scoping processor and memory timing, understanding front panel indicators, and utilizing paper tape diagnostics to locate machine failures. Specific labs are dedicated to the adjustment and troubleshooting of peripheral devices like the TU-55 and TU-56 tape transports, the TC-12 tape controller, AD-12 analog-to-digital converter, VR-12/VR-14 displays, and the KW-12A diagnostic. Additionally, the guide includes exercises on program debugging and development using Linc instructions, Linc Tape timing, and comprehensive system troubleshooting for various PDP-12 configurations (10, 20, 30, and 40 series). The labs emphasize practical procedures, often requiring the use of oscilloscopes and adherence to specific manual instructions, ensuring students develop skills in both theoretical understanding and practical application of PDP-12 maintenance and operation.
