IBM Charting And Diagramming Template X24-5884-6 Pre-owned

Up for auction is this vintage IBM Charting and Diagramming Template envelope (Form X24-5884-6). This tool was a staple for computer programmers and systems analysts in the mid-20th century (roughly the 1950s and 60s) for drawing standardized flowcharts by hand. These templates were essential because, before high-level languages like Python or Java, every logical step of a program had to be meticulously mapped out to ensure the hardware processed data correctly. The template and envelope are in very good condition and is a great volllectible from a long ago era in charting and diagramming. Will be sent USPS Ground Advantage.
