MORE ABOUT EXCALIBUR IVAN II THE CONQUEROR ELECTRONIC CHESS COMPUTER
By the time Excalibur Ivan II the Conqueror was conceived, the H8 ROMs were being phased out of production, therefore Excalibur Ivan II the Conqueror was developed around the SPLB32A processor from the manufacturer Sunplus. This created its own unique set of problems as Ron Nelson's H8 program had to be translated to work with this new processor which has a 6502 core. This processor had less available RAM therefore in order to make the program fit to these new lower specifications, adjustments were made to the program which included the removal of Nelson's Attack Bit Map Tables and the commenting out of the Ponder routine, which were both important strength of play features that existed in Nelson's H8 program. All these adjustments resulted in a new lesser strength chess program for use with the SPLB32A with its own unique play behavior.
Excalibur Ivan II the Conqueror 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.
The same SPLB32A processor was also used on Excalibur Alexandra.
