This is the only SILEX advert known so far...
|
||
|
||
It says : "Silex, a stone in our competitors garden."
|
||
|
||
Silex means flint in french, a stone mainly used in prehistoric times as tools and weapons.

Little is known about this computer. Help welcomed ! Silex means flint in french, a stone mainly used in prehistoric times as tools and weapons.
|
||
|
||
The SILEX is a professional computer released in 1979 by the french company Leanord. It was conceived from a modified Apple II board.
|
||
|
||
It has a professional keyboard with function keypad and numeric keypad. The display is built-in the system. It is monochrome but has graphic capabilities (280 x 192) and can display 40 x 24 characters (80 x 24 in option). To the right of the display is a 5.25'' disk-drive built-in the case (143 KB). Additional storage media will be available later (high density disk drives and hard disks).
|
||
|
||
Different languages were available : extended BASIC (in english and in french!), PASCAL, "evoluated disk operating system"...
|
||
|
||
The fact that there is so little information about the Silex, makes us believe that it had a very short life, at least under this name, since [SIL'Z systems](/museum/leanord-sil-z-model-5-6/) from the same company seem to be an evolution of the Silex. SIL'Z systems had some success, particularly in french administrations and schools.
