Test-14

This document details "Test-14," a diagnostic program designed to thoroughly test a PDP-14 Computer System using a connected PDP-8 I/L computer. The program identifies errors, performs halts, and provides oscilloscope looping, suitable for both quick initial checks and extensive 8-hour comprehensive testing of the PDP-14's logic circuitry.

The document outlines the system requirements, including the necessary PDP-8 and PDP-14 components, interface modules, and I/O registers. It provides instructions for loading the program using a standard PDP-8 Binary Loader, describes control switch settings, starting addresses (0200 for interrogation, 0201 for program execution), and operator interaction procedures. Error handling is extensively covered, detailing how to interpret error halts, various error messages (e.g., register errors, I/O instruction errors), and a list of module identifiers with their functions. The program executes 69 distinct tests, each described with its specific function, such as checking register operations, instruction execution, and I/O processes. The bulk of the document consists of the complete assembly language listing for the diagnostic program.
