Patch

This document describes the PATCH program, a software tool designed for the DEC PDP-12 computer. Its primary function is to allow users to modify small sections (patches) of LINCtape binary files. The manual covers hardware requirements (minimum PDP-12B), core usage details, loading procedures using the LO PATCH, UNIT command, and a step-by-step guide to the QANDA interaction interface used for inputting tape block numbers and making modifications. Additionally, the document contains the complete assembly source code for the PATCH program.
