SciSys Travel Sensor Chess ist jetzt emuliert, danke an Sean Riddle.
The same MCU ROM is in: Travel Mate, Chess Partner 5000/6000.

Danke, die neue Version ist online - hoffentlich funktioniert alles richtig trotz des 'besonderen' Datums (Freitag der 13.) ... ;)

Diesmal war wieder etwas mehr Aufwand nötig, weil ich neue Treiber ja lieber direkt in MessChess/MessExtra als im neuen MessNew implementiere, aber die Portierung nach Version 0.220 ist mir dann doch gelungen. :)

Ein Hinweis noch zum Travel Sensor Chess:
Die Taste [SET UP] ist eigentlich missverständlich, weil sie nicht wirklich einen direkten Stellungsaufbau ermöglicht, sondern eigentlich wie ein 'MultiMove' wirkt, d.h. man muß die Züge eingeben, um zur gewünschten Stellung zu kommen. Das entspricht aber genau dem 'Edit-Modus' in MessChess, sodaß zumindest das im Plugin schon mal funktioniert.
Den eigentlichen 'Setup-Modus' konnte ich aber durch direktes Speichern der Stellung im RAM ebenfalls realisieren, wobei nur die Auswahl der Seite am Zug etwas knifflig war.

Grüße,
Franz

Sean also dumped Excalibur Chess Wizard, which is a rebranded version of CXG Sphinx Seville, and has the same MCU as the old 1988 CXG Sphinx Granada. It is a HMS400 family MCU, so I'll need to write a new CPU emulator for this.

The wiki says it's by Mark Taylor, if there was any doubt about program origins: it has "(c) Copyright Intelligent Chess Software Ltd. 1988" in the ROM.

Question: Does anyone have a Sphinx Royal and/or Supra? Does it also have the HD614042SJ02 MCU? If so, does it have a Sanyo chip for the LCD, or instead cheap digital clocks or stopwatches like with SciSys Turbo 16K?

Thanks, this confirms that the MCU/ROM is exactly the same one. Do you see any chip on the LCD daughterboard?

I don't see anything but maybe you do:

ps... unless they are underneath, and I have to unscrew it?

Ok I unscrewed it.. no chips just circuit and two red bulbs or whatever you call them.

Red bulbs, I don't know what you mean by that.
one 3-pin connector and one 7-pin connector, then it's most likely software controlled and not a stopwatch or wristwatch.

It's the bulbs for the red lights a1 and b1 squares.

Ah ok, 2 leds on the same PCB as the LCD.
If there's no chip for the LCD (or maybe under the LCD panel itself), I still may be able to see how it works by examining port writes.

You will have those lights all along a1 to h1 and h1 to h8 on the Supra. It not only shows the move on the display but also lights the coordinates through the above 16 lights.

Re: Mess Emulator für diverse Schachcomputer ist fertig!
 
Supra shows the moves on the LCD, are you sure? The manual says it's for total time. There's no videos of Supra on youtube, but there's one old video of Royal and I didn't see moves shown on the LCD either.

For that reason, I was (still partially am) suspecting they went for the cheap solution and used a wristwatch or stopwatch IC.

Can you show a photo of the front side of the LCD daughterboard?

You are right it is clock only, I just turned it on. It has been such a long time since I last used it.

No worries, here it is. It is about as big as I can get it.

Re: Mess Emulator für diverse Schachcomputer ist fertig!
 
Thanks, definitely software-controlled display. No LCD driver chip indeed. I didn't realize at first that it's actually 2*2 ribbon cables on top of each other.

Strange that they didn't solder the LCD panel.

The Supra only has 1 LCD compared to Royal, so I guess it only tracks time for white? Or does it switch to black's total time when it's the computer's turn?

It switches from white to black and so on, total time.

LCD panel is 34 pins. 2 outputs from ribbon cable go to 2 LCD corner pins, possibly VCC/GND.
Then 15 outputs each go to 2 LCD pins, very odd.
2 LCD pins are N/C.

The LCD has 4 7-segment digits, or does it have more segments? Like a blinking colon (I didn't see any on photos online), or DP (display point, at bottom-right of a digit).

I don't see any blinking colons. It counts from right to left. Once it gets to sixty it switches to the third digit and shows a 1 the fourth digit remains at zero so you have to wait to 10 minutes before the 4th digit would change. I don't want to run it that long but the 4th digit probably goes to 99 minutes before it goes back to zero. (That's my guess).

From a display perspective you have two left digits and two right digits with a small gap in the middle that is dark (no ticking dots).

When the computer is thinking it has a small LED called "Think" that lights up red. There are 4 small LEDs there from top to bottom called "Level" "Set-UP" "Think" and "Threat".

You know, computers like the Supra, Royal, other CXG's and some Excalibur's their maximum level 64 only plays at maximum 20-25 seconds per move. These are the types of computers where it would be really great if revised versions could be created where levels are changed to add maybe 30 seconds and 3 minutes per move. That would really allow us to see what their play strengths are. If that were ever possible.

Nick, die Seville-Klone gucken ja nur 1 Ply voraus, darum brauchen sie auf dem höchsten Level nur ca 30 Sekunden.

Siehe mein Post:
https://www.schachcomputer.info/foru...8&postcount=13

David Levy hatte mir mal die Funktionsweise dieser 1-ply Schachcomputer erklärt, hier ein kleiner Auszug aus seinem Mail:

Zitieren:

Yes, you are right that it is basically a swapoff algorithm.

Because of the RAM limitation I came up with the idea of evaluating each square on the board sequentially, and when the calculations for a square were completed the net score for that square was added to a cumulative value. From what I remember there were three main components for the square score - one was a positional evaluation (each piece gets a certain score for the square it is on); one is a mobility count - 1 point for each piece that attacks this square; and the most significant was the swapoff value. I don't recall if there was anything sophisticated in the swapoff, for example a rook acting through a queen is different to a queen acting through a rook, and I can't recall if there was an upper limit on the number of men on each side which could participate in the swapoff on a particular square, but I do recall that it worked reasonably well. If, as I suspect, you have one or more of the products using my algorithm, you could conduct some tests in order to work out the level of sophistication of the swapoff function.

There were also some bonus scores but I can't recall the details, though I believe one of them was a "push passed pawn" bonus; one was a penalty for losing castling rights. Until a few years ago I still had the source code, but then a pipe burst in my cellar and the paper was destroyed.

I also devised an algorithm for mating with KRvK and with KQvK - both were rule based I think, and both were in the code.

...

The algorithm starts by looking at square a1. It cycles through every piece on the board and when it encounters one which attacks a1 it adds to the "score for the current square" variable whatever is the appropriate score for that piece.

Hi Michael,

Danke, das passiert, wenn man sich 5/6 Jahre lang nicht mehr mit dem Thema beschäftigt und all diese alten Diskussionen vergisst :) Dann stellt man sich diese Fragen immer wieder neu.

Wenn das der Fall ist, wäre es interessant, diese Tests mit einigen Computern bei 1 Ply durchzuführen und Levy's Methode mit anderen bei 1 Ply zu vergleichen.

Celadus in Hiarcs Post fragte neulich nach der Stärke von Alexandra bei 1, 2, 3 und so weiter Ply's.

Vielleicht lohnt es sich, eines Tages ein paar Computer zu nehmen und diese Tests in den einzelnen Ply durchzuführen und die Ergebnisse zu vergleichen. Vielleicht kann man dann sehen, ob Levys Methode tatsächlich eine Verbesserung darstellt, wenn man mit 1 Ply spielt.

Ok nichts mehr zu diesem Thema unter Mess um die Mess Polizei zu vermeiden :)

Gruss
Nick

Hi...

Da es um Emulation geht , habe ich Bing Chat gefragt, wie schnell ein
Super Constelltion sein muss, um auf 3000 Elo zu kommen. Hier seine Antwort...

Der Novag Super Constellation Schachcomputer hat eine ELO-Zahl von etwa 1811 bei einer Taktfrequenz von 4 MHz. Um eine ELO-Zahl von 3000 zu erreichen, müsste er eine enorme Steigerung seiner Rechenleistung erfahren.

Basierend auf der nicht-linearen Beziehung zwischen Rechengeschwindigkeit und ELO-Zahl, könnte man schätzen, dass der Computer etwa eine Million Mal schneller sein müsste, um in die Nähe einer ELO-Zahl von 3000 zu kommen. Dies ist jedoch eine sehr grobe Schätzung und hängt stark von der Effizienz der Algorithmen und der Nutzung der zusätzlichen Rechenleistung ab.


Was haltet ihr davon ?

Mark 1

gar nicht so dumm, dieses Bing Chat! ;)

Üblicherweise sagt man ja, daß eine Verdopplung der Geschwindigkeit etwa 60 Elo bringt.
Bei ca. 1200 Differenz (3000-1800) bedeutet das also 20 mal verdoppeln (1200/60), also 2^20, was ziemlich genau 1 Million entspricht.

Du brauchst also nur in CB-Emu für den SuperConny eine Frequenz von 4 THz einstellen. :D

Franz

Nichts! Denn der Super Conny wird nie 3.000 Elo erreichen ... vielleicht 2.300, dann ist Schluss, egal wie schnell ...

Aus diversen Gründen ...

1.) Jede zusätzliche Verdoppelung bringt weniger als die Vorherige ...

2.) Der Speicher und damit die Rechentiefe ist begrenzt ...

3.) Sein Wissen bleibt sein Wissen ... bedeutet: In vielen Fällen wird er sich aufgrund seiner "Überzeugung" für den falschen Zug entscheiden.

Darum ist keine beliebige Steigerung möglich ... wie man ja am Phoenix und seinen Emus sehen kann ... die Steigerungen werden schon jetzt immer geringer ...

Und es zeigt sich, wie wenig diese KI Bots wirklich "wissen" ... :zwinker:
