<< >>
Description
This rectangular blue-green flowcharting templatet has a scale of inches divided to tenths at the top and a scale of inches divided to eighths at the bottom. Twenty-five holes representing various logical operations are cut in the plastic. A white paper sleeve has definitions of the symbols on it. The device is meant for use in conjunction with a worksheet with IBM number X20-8021. A mark on the object reads: IBM FLOWCHARTING TEMPLATE FORM X20-8020. A mark on the envelope reads in part: Have you considered using IBM’s System/360 Flowchart (/) Program? The IBM System/360 was announced in 1964 and sold from 1965. The donor of this template, Terry M. Sachs, was trained to program the IBM System/360.
