Sean also dumped Excalibur Chess Wizard, which is a rebranded version of CXG Sphinx Seville, and has the same MCU as the old 1988 CXG Sphinx Granada. It is a HMS400 family MCU, so I'll need to write a new CPU emulator for this.

The wiki says it's by Mark Taylor, if there was any doubt about program origins: it has "(c) Copyright Intelligent Chess Software Ltd. 1988" in the ROM.

Question: Does anyone have a Sphinx Royal and/or Supra? Does it also have the HD614042SJ02 MCU? If so, does it have a Sanyo chip for the LCD, or instead cheap digital clocks or stopwatches like with SciSys Turbo 16K?
