Almost ten years after having conceived the Micral, world first commercial microprocessor based computer, André Thi T. Truong, joined the young Normerel Company managed by his old friend Jean René Tissot.
In a short time, he designed the OPlite, first computer Normerel would produce.
The Oplite was a PC compatible system featuring some innovative concepts. The case held a dual floppy disk drive and a removable 9-inch display. Standard connectors allowed an external colour TV set, a RGB or composite monitor to be used. The case also provided room for four long expansion cards.
To reach a high level of sales, Normerel joined together with Rank Xerox. The OPlite was thus sold in the large French 'Xerox Store's network alongside Apple, Toshiba and other well-known brands.
Later, Normerel would sell several PC and AT compatible systems. They made a joint-venture with ADDX Systèmes and formed ADDX-Normerel.
In 1989, the company which lost a lot of money, was bought by SMT-Goupil. Finally, Normerel closed its doors in July 1998, the same year as SMT.
