This document, titled "Memory Addressing Test Program" (M-1121), dated August 9, 1961, outlines a maintenance tool designed for the PDP line of computers. The program verifies the correct functioning of memory address registers and decoders by filling memory with unique address identifiers and performing checks. It includes operational instructions, such as using sense switches to control testing modes, loading the program via tape, and handling error reporting. Additionally, the document provides the assembly source code for the address checker routine.
