connection. As originally released, the Maxim was fitted with a PS/2 mini-DIN interface; versions compatible with Macintosh and Sun were released in bundles with interface conversion boxes. The keyboard was reconfigurable to use the Dvorak layout by selecting the appropriate driver in Windows. The accessory keypad connected using an RJ11 connector. A USB version was released in 2004; it uses a passive adapter for PS/2 compatibility. With the USB update, the keypad was revised to incorporate a USB hub. It was named a PC Magazine Editor's Choice that year in a comparison of keyboards. Savant The Savant and Savant Professional were keypads with 20 and 58 unlabeled keys, respectively; each key could be programmed with up to 480 (Savant) or 915 (Savant Professional) keystrokes. They were designed and produced by P.I. Engineering and marketed by Kinesis; P.I. Engineering marketed identical products as the X-keys Desktop and Pro. Interfaces / Evolution The Interfaces keyboard was developed by Cramer, Inc. as a split keyboard mounted on the user's chair arms. Kinesis assumed responsibility for manufacturing the Interfaces in 2000, then released an updated version in 2001 as the Kinesis Evolution. The Evolution added programming capabilities and included a bundled touchpad pointing device that could be moved to the left or right halves. The cable connecting the keyboard to the computer was long, while the cable linking the halves was ; mechanical, tactile keyswitches were used. To improve flexibility, track-mounted (taking the place of an underdesk tray) and desktop configurations of the Evolution were released. The specific model number depends on the mount style chosen and the trackpad options, which were for the left, right, or both sides. Freestyle The Freestyle keyboard line was launched in 2007; like the Maxim, the Freestyle was a staggered-column keyboard split into two halves, but each half was an independent module now, linked by a cable. The keyboard halves were sold as the Freestyle Solo, and was bundled with the PivotTether, which allowed any arbitrary split angle. Initially, several additional accessories were released with the Solo, including palm rests (AC706), the Incline (AC710, a base providing a fixed 10° tenting angle and adjustable split angle) and the VIP (AC720, adjustable 10°/15° tenting angle via lifters on each half). The next year, V3 (AC730) and Ascent (AC740) tenting accessories were also offered; the V3 allowed tenting angles of 5, 10, and 15° without palm rests, and the Ascent
