Editing IBM Adjustable Keyboard (section)

==History==
The M15 originated at Lexmark in 1993. Regular production appears to have began in 1994. Lexmark manufactured the M15 for IBM, who marketed it as the IBM Adjustable Keyboard through their Easy Options accessory brand/service. The IBM Adjustable Keyboards have been spotted with two different logo styles - "Options by IBM" (more common) and a standard blue IBM logo (less common). Lexmark themselves also marketed the keyboard directly to the public as the Lexmark Select-Ease. 

The M15 was the subject of a patent dispute from Mark Goldstein, founder of the Goldtouch company, over the design of the adjustable ball joint, and was settled by a subsequent licensing agreement. In late 1995, Lexmark sold off certain designs and tooling relating to buckling spring keyboards, including the tooling necessary to make the M15, to Maxiswitch. Maxiswitch never produced any M15 keyboards themselves, and attempts to reacquire the tooling by interested parties have proved unsuccessful.
