Hi,
I opened a CP3000 and found a scalable resistor from 3 ohm (pos. 1) to 100k ohm (pos. 8), two wires to the circuit - one connected directly to a cpu pin, the other to some connected resistors/capacitators.
The calculation time of the levels is equal between mini and 3000 at lev 1 (about 4 sec.). Mini has max-time of 15 sec. at lev two and 3000 20 sec at lev 8.
CP4000 has also a max-time of 20 sec. at lev. 12.
So the only remaining question is the difference between the highest level 2 (5 to 15 sec.) of the mini-clones and the max-level of the 3000/4000 of 5-20 sec. - if the manuals are correct...
Very similar are CP5000 and CP6000, that are clones of Travel Mate/Travel Sensor Chess - these items have 4 Levels from 7 sec. avarage at L1 und 54 sec. av. at L4.
Difference are sensor recognition of figures, so it is a different rom, but perhaps the engine is the same at a different speed?
Regards
Achim

The game keeps checking the 1-bit level switch while it's calculating its next move. On CP3000 PCB photos, the level slider is still connected to that single MCU pin. They must have added an oscillating circuit on the level slider.
So, level 8 on CP3000 will be as strong as level 2 on Mini Chess(disregarding possibility that CP3000 CPU is higher clock freq)
and on let's say level 4, the actual level is "2" 50% of the time, and "1" 50% of the time.
