Read Binary Test Program

This document provides an overview, operating procedures, and technical details for the MAINDEC 10 Read Binary Test program. The program is specifically designed to evaluate the reliability of the PDP-1 photo-electric paper tape reader during binary operations by reading a closed loop of tape containing alternating patterns of ones and zeros. It detects specific reader malfunctions, such as dropping or picking up bits. The manual covers required materials, console operation, loading sequences, error handling procedures, and diagnostic applications including high-speed, brake, and margin tests. The document also includes the source code listing for the test program and an auxiliary tape-generation program.
