hpmuseum.net →The 9100A was the first technical desktop computer introduced by Hewlett Packard. The 9100 could also be considered a calculator. It did not have an alphanumeric keyboard, and most functions were effectively "programmed under" individual keys on the keyboard, similar to a modern-day non-programmable trigonometric calculator. The 9100A used a keystroke sequence known as Reverse Polish Notation (RPN). The 9100 had a three-line CRT display and built in mass storage (magnetic card drive). Optional peripherals included the 9120A thermal printer and 9125A single-pen plotter. The 9101A provided additional external storage for the 9100. The 9100B was introduced in 1969. It had 3840 bits of core memory, compared to 2208 bits in the 9100A. Click here to see a video of Steve Leibson interviewing Tom Osbourne, inventor of the 9100 (from Cody, Wyoming).
