Calco 12

CALCO 12 is a software program developed in DIAL for the PDP-12 computer to facilitate the rapid plotting of large data volumes on the Model 565 CalComp Plotter. It provides features such as axis drawing, user-defined origins, and configurable point counts. The program uses the QANDA and Incremental Plot subroutines. The documentation details hardware requirements—specifically EAE and at least one LINCtape unit—and provides step-by-step operating instructions for loading the program, entering data parameters, and configuring plot settings via sense switches.
