Math is Fun.

The HP 9820A (AKA the 9800 series model 20) was HP’s third calculator. It made use of many of the same parts used to make the HP 9810. In fact, a number of PC boards were interchangeable between the two. There was, however, a major distinction: The HP 9820A was HP’s first algebraic calculator. It was a fully algebraic calculator with parentheses, precedence and even implied multiplication. (e.g., 2AB meant 2 times A times B.) The calculator displayed the expression as entered on a single line alphanumeric LED display (which showed 16 characters and scrolled as needed) and evaluated it when the EXECUTE key was pressed.

The HP 9820A was originally priced around $5,000 to $6,000 circa 1972, approximately $44K in 2026 USD.

Note that the shop advert is a screen; the windows are visible. It’s around the corner down the street somewhere (or was). Presumably the building shown is (or was) on Bowery Street. Original photo by Tom Webb found in here, overlaid colorized portion by unknown. [Related post here.]
