Hi Michael,

interesting news
Mini, Junior and Graduate are nown as clones (all have 2 Levels with a mechanical switch).
CP3000 has 8 Levels and CP4000 12 Levels by mechanical switches - how did they do it with the same ROM? Are the switches fakes (all result in only 2 positions)?
If not, they must still have planned the later versions with more levels - and then it should be possible to extend the older items with more levels by changing the switches...

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.

Some unrelated corrections to emulation I might as well mention here:
Mephisto Almeria until Vancouver, and Berlin too, are 12.288MHz, not 12.0MHz.
Novag Super Expert C that was thought to be version 1.2 is actually 3.0.

Hat jemand ein Leonardo oder Galileo, und konnen Sie bitte ein video recording(mit ton) machen von einschaltung?

I would like to see the LED test of the keypad during power-on, and also want to hear the sound beeps. I don't need to see the chessboard, just the keypad.

Ich habe jetzt ein video recording, danke!
Ok, I was sent a video recording.

For anyone else that has read the previous message and was also going to record a video, thank you, but it's not needed anymore =)

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?

Thanks for double checking. Yes, that thing will oscillate the CPU pin (the same pin that is directly connected to the level switch on Mini Chess)

*edit* the mysterious increased max calculation time from 15 to 20s mentioned in the manual, most likely a correction after they found out that occasionally it can take up to 20s.
If not, then it means CP3000/4000 CPU speed is slower than Mini Chess, but that is unlikely.

Yes, I expect Travel Sensor, Travel Mate, CP5000/6000 to be the same Mark Taylor chess engine.

Saitek Leonardo und Galileo laufen bei mir schon ...

Hallo,
der Leonardo hat doch einen 6301Y. Der Novag SuperVIP auch.

Darf man sich da Hoffnung machen ?

Oder benutzt der Leo das integrierte ROM nicht und der SuperVIP aber schon ?

Der SuperVIP hat ja auch 32kB extra Eprom.

Weis man schon ob der das interne nutzt ?

Gruß
Rudolf

re: Leonardo/Galileo, yes they are playable now after I fixed the lockup problem yesterday (bug in CPU timer). I still need to hook up battery-backed RAM and the GO/ACL/STOP buttons.

Leonardo indeed has a 6301Y, but it is operating in external mode. The internal rom (that isn't dumped) is luckily unused.
I think in the case of Super VIP, the 16KB internal ROM is actually used.

Funny fact: the MCU SX8A 6301Y0G84P in Renaissance is actually the same one as in Saitek Conquistador. In other words, they used leftover stock 6301Y in place of 6303Y.

hap, your todays changes have broken the LCD display of the Fidelity Phantom.

BTW, are you now also starting to make all kinds of (useless) changes to working chess drivers like some other MAME developers? Annoying ...
