Ok, in my version I've added all 4 frequencies (3/3.6/6/7.2) and set it to 3.6 by default, so everyone can choose whatever he wants.
Hello,
I have tested chess computers Scisys Chess companion II and Star chess and there emulation on mame.
I use the Pb5 of "Europe Echecs"( checkmate in 4 moves) with level 8 on CC2 and level 16 (H) on Star Chess.
Scisys companion use a external clock without crystal,
Star Chess use a crystal at 7159090 Hz.
CC2 find checkmate in 15 mn 03 : 903 seconds.
Star Chess find it in 8 mn 13 : 493 seconds.
So MY real (not modified) Scisys Chess Companion II have a clock at 7159090*493/903 = 3908562.
It would be interesting to know if others CC2 lasts the same time.
The emulated Star Chess, with a defined 7150900 Hz crystal, take the same 8 mn 13 s to find the chekmate in 4.
Cordially.
