Ivan The Terrible, (Excalibur 701E Ivan The Terrible)
a talking dedicated chess computer by Excalibur Electronics, released in 1996 [2]. The computer has a Hitachi H8/3216 controller running at 12 MHz with 48 KiB ROM and 2 KiB RAM, and features a press sensory board along with LCD, button panel and speaker. The program was Ron Nelson's further development of his H8 program of the Excalibur Mirage applying a tactical quiescence search due to attack maps, adding sound effects and speech synthesis with his own compression algorithm [3]. Evaluation tuning was supported by chess consultant Larry Kaufman, who was also responsible for the opening book [4] [5].
