The Elan Challanger was an IBM-AT clone produced by Leanord in 1986. The Elan team developed its own BIOS and all the electronics for the system. The team started in 1985 with development on the 8088, and then the 80286 processor.

The computer is a standard AT compatible system. The system had a unique feature that allowed the CPU speed to switch between 8.77MHz and a Turbo 12MHz mode by using an external DOS command. The machine was mostly limited to the French market, with the government and the French educational system the main buyers.

Graphics capabilities of the machine varied by the Video Card that the customer bought for the system. It supported CGA, Hercules and a high-color EGA video card.

Leanord is the name of a computer hardware company from Lille France. It was founded by Bernard Pronier. After producing and marketing a few orignial microcomputers, Leanord produced an Apple II clone which was branded the Leanord Silex. When CP/M became more or less a standard operating system, driven by Digital Research, the company switched and started producing Z80 based systems, such as the SIL'Z 3 and later produced Intel 8088 based MS-DOS machines like the SIL'Z 16. Leanord kept producing clones, in fact,t he SIL'Z 16 is a clone of the American FX20 by Future Computers. Leanord made some modifications so it could produce the computer on its assembly lines in Lille, but it basically remained the same machine as the FX20.
