LogAbax was a French computer brand. Founded in 1942, the company was one of France's pioneers in computer manufacturing. The name is composed of two abbreviations: Log from logarithm and Abax from abacus.[1]

History

The company was created in 1942 as “La Société Française des Brevets LogAbax”. In 1947 it employs twenty people and has a factory located at Malakoff. The company obtains a contract from CNRS for the construction of a "Couffignal machine", intended to be the fist French "electronic calculation machine".[2] Between 1948 and 1950 LogAbax studies an electronic meter, related to the electronic calculator development.[3]

In 1968 LogAbax and Bariquand et Marre merge, forming LogAbax SA.

The LX 500, a personal computer based on the Z80 microprocessor and running the CP/M operating system, is presented in 1978.[4][5]

Due to poor results in the late 1970s,[6] LogAbax files for bankruptcy in 1981, with Olivetti becoming the majority shareholder, creating a new entity named Société Nouvelle LogAbax.

The Persona 1600, a PC compatible machine with an Intel 8086 CPU (similar to Olivetti M24) is presented in 1985.[7][8] Other rebranded Olivetti PCs follow (Persona 1800[9] and 1300[10]).

In 1988 Olivetti France and Société Nouvelle LogAbax merge, becoming Olivetti-LogAbax.
