<p>The CAB 500 was planned by SEA as a low cost, simple to use computer, primarily for scientific calculations. The technology used was magnetic amplifiers, transistors, ferrite cores, and a magnetic drum, with input/output on perforated paper tape. It could be used in two modes: as a stored program computer or as a desk calculator. It was a micro-programmed machine, and a high-level language PAF (Programmation Automatique des Formules) was developed for it. It was launched in 1960 and over 100 were sold.</p>
