Quote:The functionality of calculator ICs increased at a rapid pace and Roberts was designing and producing new models. The MITS 7400 scientific and engineering calculator was introduced in December 1972. It featured trigonometric functions, polar to rectangular conversion, two memories, and up to a seven-level stack. A kit with a three-level stack was $299.95 and an assembled unit with a seven-level stack was $419.95.[29] The next month the Series 1200 four-function pocket calculators were announced. The six-digit model was $59.95 and the twelve-digit model was $99.95.

See Wikipedia article on MITS here

The key phrase of course was "before they became a mass consumable item" not "exceeding anything commercially available at the time." Two entirely different claims Smile


Who decides?
