Hello,

The response time for “Mach II,V” is under emulation (Mame).
All others response times are taken from Nolot published in "Europe echecs" and available at https://www.blitzchess.fr/fr/tests/europe-echecs/88-90/ .
However, I checked 2 positions (Cb7 and Cb10) with emulations (Mame, CB-emu) with the 2 sets available for LA version (fex68km2,fex68km2a),
so it seems that Nolot has received from Fidelity/Rexton a Mach II at 13,78 MHz (74' vs 85' for the last).
If I remember correctly, it is not the first time Fidelity/Rexton gave it an overclocked chess computer for testing.

Cordialy,
