The Executive Chess just beat the Novag Micro Chess peg sensory onto the market. With a further years development behind it the LCD chessboard was more evenly lit than the Super System III example and more reliable. The cursor input method is a little slow but this type of portable had the advantage over the peg sensorys of no tiny pieces which were  fiddly to handle and could fall out of the board. In 1980 Mattel had produced the first pocket-sized LCD chessboard chess computer. In comparison with that, and by modern standards, the Executive is a bulky and heavy portable machine.

Promotion of the Scisy Executive Chess 1982 style (above) and in 2007 with cuckoo clock. Judged by the numbers seen on Ebay the Executive Chess did not sell very well. The price in the UK was 89.95 (about 250 at 2007 prices)
