SciSys+Leonardo

a dedicated chess computer by SciSys released in 1986, featuring a full sized wooden magnetic sensory board with file and rank [|LEDs], expandable with modules with own processors and programs. Opposed to other dedicated modular chess systems, the Leonardo already had a basic program on board - written by Julio Kaplan and Craig Barnes of Heuristic Software, running on a 6800 compatible [|Hitachi] 6301Y controller, which was also the program of the none modular //SciSys Turbo S-24K//. || toc =Tournaments= SciSys Leonardo played the Aegon 1986 with two wins and a draw, and the Aegon 1987 where it drew two games out of six.  =OSA= SciSys' or Saitek's //Open System Architecture// (OSA) implements a [|serial connection] of the Leonardo, or its subsequent models Galileo or Renaissance to home computers or PCs. The OSA link cable [|converts] [|TTL] to [|RS-232] levels and vice versa. This allows to use the sensory board as move input device of chess program GUIs such as Arena, or the dedicated user interfaces like Gavon.  =Saitek Galileo= In 1988, one year after SciSys became Saitek, the Leonardo was renamed the Galileo for copyright reasons and the machine was upgraded for faster response.  =Saitek Renaissance= In 1989, the Renaissance board appeared with almost the same base program and featuring [|LCD] and 9x9 square indicator LEDs - four sorrounding each square, and analyse and autoplayer modes.
