The HP 9100 is the first calculator Hewlett Packard produced in the late 1960’s. This extremely interesting machine does not contain any digital circuits. The magnetic core memory uses a small CRT display screen, which displays three rows of characters.

We have a copy of HP 9100 just here at PEEK&POKE Computer Museum, which was a generous donation of company Rijekaprojekt who used it for years and years. The machine still works perfectly.
