Paul Courbis

Paul Courbis (born 3 November 1967), is a French programmer, mostly known for reverse engineering the HP-28 and then the HP 48 series of calculators, and writing multiple articles and books disclosing his findings. These books had a surprising success in France.

Very soon, a team of enthusiasts formed, gathering around Maubert Electronique, a small electronics shop in Paris' Latin Quarter, and developing a large number of utilities and games (one of the most impressing one was Pac-Man for the 48, one of the first programs using the hardware scrolling device of the 48). Most of these programs are still available and can be traced back to the original reverse-engineering published by Paul Courbis.
