LX-500 series were first microcomputers from Logabax, a French computers manufacturer specialized in small and medium size computers aimed at private and state-owned companies.
It was a stange looking small metal box containing a single multifunction Z80 based card and two 90 KB 5.25" floppy drives. A serial port allowed the Logabax video terminal to be connected. A few months later, several versions appeared (LX-525, LX-528) featuring a cheap plastic case, but 710 KB floppy drives and two extra Serial ports. The system ran Logabax DOS and a flavour of CP/M Operating System.
In fact, due to its very expensive price for the time (about 4000 Euros) the LX-500 never met success near private companies despite Logabax efforts in setting up an European dealers network.
However, at this time French ministry of education sought french computers to equip thousands of high schools. Only two French manufacturers were able to provide such small systems: R2E (with its 80-20 series) and Logabax. Thus Logabax got more than half the ministry contract and several thousands systems were installed in classrooms, even though the system was far to meet reliability and ease of use requested in educational environment.
Despite Logabax had priviligied access to procurement contracts with French state, the company met serious cash shortage problems. After several vain attempts from French government to refloat the company, Logabax was eventually sold to Olivetti, the first Italian computers company. After some common ventures (Olivetti-Logabax Persona PC systems), Logabax finally disappeared for
