Abstract

A program card comprised of passive elements is collocated or otherwise considered part of the cathode ray tube, CRT, module of a modularized display unit, and is used to dictate major system operating parameters to a set of cooperating electronic modules. This concept allows an appropriate standard set of electronic modules to drive CRTs of differing deflection angles, screen and neck sizes. Sparing cost and logistic complexity can be reduced at field installations which utilize CRT displays of various sizes.
