Unicomp GA LLC (formerly Unicomp, Inc.) is an American manufacturer of computer keyboards and keyboard accessories, based in Lexington, Kentucky. The company was founded in 1996 by ex-IBM and Lexmark employees. Unicomp is the current license holder and manufacturer of Model M keyboards using buckling spring key switches, the patents for which they purchased from Lexmark in 1996.

History

In 1996, Lexmark International was prepared to shut down their Lexington keyboard factory where they produced Model M buckling-spring keyboards. IBM, their principal customer and the Model M's original designer and patent holder, had decided to remove the Model M from its product line in favor of cost-saving rubber-dome keyboards.

Rather than seeing its production come to an end, a group of former Lexmark and IBM employees purchased the license, tooling and design rights for buckling-spring technology, and, in April 1996, reestablished the business as Unicomp.

Since 1996, the tooling and molds that Unicomp had inherited from Lexmark began to wear out, leading to a gradual decline in build quality and finish. However, in 2020 Unicomp replaced its tooling leading to quality improvements. The company also began shipping new designs at this time.

Unicomp's product line consists largely of modified designs based on late Model M keyboards produced by Lexmark:

• Classic, (formerly called the Customizer) is similar to one of IBM's late Model M variants and is built on the same tooling. The only changes to the Classic compared to an original Model M are the logo, Windows keys, optional USB connectivity (as an alternative to PS/2), and the option for a black case with light gray or white keys (as an alternative to the classic "pearl" beige).
• Classic Trackball, a Classic with a trackball and two mouse buttons right above the indicator lights. However, it is not currently being produced due to low demand. ^[1]
• PC 122, a 5250 122-key keyboard similar to the Classic, but with a rearranged layout and an extra set of function keys, and many keys moved to the left side of the keyboard, and the home key moved to the middle of the arrow keys.
• Ultra Classic, (formerly called the SpaceSaver) is a lighter, more compact version of the Classic. An Apple keyboard variant for macOS computers is sold under its former name of SpaceSaver M.
• EnduraPro, is an Ultra Classic, except with a TrackPoint nub and two mouse buttons at the bottom inspired by the ThinkPads keyboards.
• New Model M, a full-sized keyboard resembling an up-sized version of the Ultra Classic design. ^[2] There is also a variant for Apple macOS computers.
• Mini M, a TKL (tenkeyless) version of New Model M with the lock lights moved from their traditional location above the now-absent numeric keypad to the top edge of the board above the F9-F12 keys.

Unicomp also offers a repair service along with replacement and custom parts for virtually all Model M and similar keyboards made by IBM, Lexmark, Maxi Switch, and Unicomp.
