Hi dear chess computer friends,

I just wanted to point out a "reverse" way to make use of the nice Mhz setting feature recently added by Franz (thanks a ton!).

Should you need to calibrate the actual clock speed of a chess computer you own, which is available within the emulation package, you can tune the Mhz value using a trial & error process, until the resulting emulation and the physical device provide the very same response times.

As an example, I knew my Fidelity Sensory 9b was slower than the 2Mhz standard device. I could observe it thru positions testing, my 9b response times were always proportionally longer than the expected values. The ratio led me to the conclusion my 9b clock was rather 1.8Mhz. Well, I get accurately simultaneous answers after setting the emulation to 1.88Mhz! So I am now happy with a more accurate information about my device, and a Mhz setting I can keep registered (fscc9.mhz file in mhz folder) so that the emulated device behaves 100% the same as my personal 9b. Isn't that great?

Eric
