In that days Rebel was able to look 6 plies deep all very selective and much holes involved but very effective playing a program thinking just 4 plies deep. >>In the past I have written an Apple IIE emulator for the PC. > >That's incredible! Did you write it just to run a 6502 Rebel with more >comfort, or did you make a standalone product of this emulator? The emulator was only meant to work for my convenience improving Rebel. No Apple 2E hard disk, keyboard or screen support, it only emulated my engine. It was not used very much as the so-called "dedicated computer" market collapsed after the introduction of the 80486 as then it was the first time producers like Mephisto, Fidelity and Saitek couldn't compete anymore regarding raw processor speed as the 486 definitely was superior to the chips they were using. The only exception was TASC who came with the ChessMachine concept and therefore was able to compete a bit longer but then when the Pentium 90 came the hardware superiority once and for all was decided in favor of the PC. Summarizing my conversions: - TRS80 (basic) - TRS80 (assembler) - APPLE 2E (assembler) - ARM RISC (assembler) - PC (C++) - PC (assembler) Every stage was about 1.5 - 2 years before I was pleased with the results. I wonder what is next. The upcoming 64-bit of Intel? >> I can run and old >>6502 Rebel on the PC. It's a super fast emulator, speed loss not more than >>a factor 2-3 if I remember well.

I will ask Jeroen to edit the Tiger book a bit :) Ed
