Applications

The SummaSketch II Plus series was Summagraphics' mainstream line of professional digitizer tablets, widely used from the late 1980s through the mid-1990s in engineering, architecture, and graphic design workflows. Tablets like the MM II 1201 were standard input devices for DOS- and early Windows-based CAD programs including AutoCAD, where a stylus or cursor puck allowed drafters to trace drawings, enter precise coordinates, and operate menu overlays far more efficiently than a mouse. Summagraphics (headquartered in Seymour, Connecticut) was one of the dominant digitizer manufacturers of the era alongside Calcomp and GTCO, and their SummaSketch line was particularly popular in mid-range professional settings. Today these tablets are sought by legacy CAD users maintaining older workstations, by hobbyists running period-correct DOS setups, and by collectors of early computer input devices.
