THINKING ON THE OPPONENTS TIME: As you play you will notice that the computer may reply to your moves instantaneously. This is because the computer thinks while you are thinking, using the same time you are contemplating a move to plan ahead and develop its strategies. The IGOR will try to anticipate the move you are likely to make and calculate a response for that move before you have made the move. If it has guessed right, it will strike immediately and play the move it found while you were thinking.

MORE ABOUT EXCALIBUR IGOR ELECTRONIC CHESS COMPUTER
For many years there had been a lot of discussion regarding program authorship due to a lack of documented information on Excalibur Electronics specifically pertaining to their early day migration from distributor and reseller of chess computers to manufacturer. Ron Nelson author of the first chess computer sold to the public in his days at Fidelity Electronics and later the main person at Excalibur Electronics for programming and developing chess computers, in December 2015, began reporting on the history of Excalibur Electronics as well as Fidelity Electronics, attempting to fill in many of the historical gaps.
Ron Nelson reported that Excalibur Igor was developed by him, using a new program that he wrote for the H8 processor which incorporated some of his new ideas, including the implementation of Attack Tables, a concept Nelson had years previously observed on some Spracklen computers at Fidelity Electronics. Nelson learned the ideas behind Attack Bit Map Tables through subsequent interactions with Ken Thompson who explained to Nelson how the Belle Attack Bit Map Tables worked in practice. Nelson went on to write his own Attack Bit Map Tables with additional new ideas that he wanted to try out that are now incorporated in Excalibur Mirage, Excalibur Ivan, Excalibur Grandmaster and Excalibur Igor electronic chess computers.
GM Larry Kaufman was engaged as a chess consultant by Excalibur on the advice of Nelson to assist him in fine tuning the chess knowledge of the new H8 chess program that Nelson initially programmed into Excalibur Mirage and later also implemented in his future other H8 processor models, Ivan, Grandmaster and Igor.
Excalibur Igor was contracted for manufacturing by Excalibur Electronics to the EWIG Industries Hong Kong Office in Kowloon which is a subsidiary of EWIG Industries Macao Commercial Offshore Limited in Macau whose electronic manufacturing factory is situated in the Guangdong Province of China.
