Léanord (Laboratoire d'Electronique et d'Automatisme du Nord) was a French computer brand, founded in 1960 at Haubourdin, near Lille.
Based on a licensed Apple II motherboard with a MOS 6502 running at 1Mhz and 32Kb RAM, the machine was expensive for the time (costing 29,000 Francs) and came with SILBasic (a BASIC interpreter), SILPascal (a Pascal interpreter) and SILDOS (a disk operating system).
[6][7][8][9] It was powered by a Zilog Z80 at 2.5 MHz, had 64 Kb of RAM, 80x24 character monochrome display, two 5'' 1/4 320Kb disc drives, two RS-232c ports (for printer and modem), and measured 54x33x57 cm.
In 1983, the Sil'z IV was released, with a different design featuring a separate keyboard and monitor and adding a hard drive.
[10] The Sil'z 16 was released in 1983 with relation to the Computing for All government program, featuring the Nanoréseau,[11][12] a small network based on the RS422 standard, and developed in connection with Lille university.
