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 ?

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 ...

LED handling is wrong in some of the Mephisto drivers, I clean those up. For the users, the most obvious one is the missing tri-color leds. If you don't like these changes, simply don't copy them over?

hap, I saw that you've already implemented this SED1502F driver for the Renaissance, so I have a short question:
could I already add this 7seg info line in my artwork, or does this only work after the LCD board (SVG) has been finished, too?
I've tried it with screen index="0" (like in other layouts), but this doesn't work.

Just like when Stratos was 1st added, LCD outputs are not known yet.

I'm hoping that the LCD is exactly the same as the one in other Saitek chesscomputers. From photos it does look the same, but it's not certain that the hardware is identical for all of them. And if Saitek Simultano is dumped, it could be used for that driver as well.

beside the opening, simultano and stratos playing the same moves
