Description

HP's first calculator, introduced in 1968, at $4900.00 Log, trig, and other functions could be performed with a single key stroke. Computer- like memory allowed the calculator to store instructions and constants for repetitive or iterative solutions. Programming consists of pressing key in a desired sequence, with any key available as a program step. The program capacity was 196 steps. Magnetic programming cards can record two 196-steo programs. The add-subtract speed is 2 milliseconds. Until the HP35, the 9100A represented the most advanced calculator one could buy. Exhibit label: "The HP910)A is a desk calculator and a stored program computer that was designed for engineering and scientific calculations. It cost little more than half a PDP-8?I for about the same amount of physical hardware and could calculate a floating-point square root faster than the IBM System/360 Model 30."
