Nice old stuff Thorsten.
yes its also interesting to see how competitive Colossus Chess4 (commodore C64) and Clock Chess89 (ZX Spectrum) were, if you would have given them appropriate hardware.
e.g. C64 had only 1 mhz !!! here in my tournament it runs with 5 mhz instead. 3.7-5 mhz was the normal speed in our dedicated chess computers. so not really SPECIAL. or ZX Spectrum runs with 3.5 mhz normally. And it is 1/2 as fast as 6502. so by giving it 10 mhz it should be as good as the 6502 with 5 mhz.
So roughly Clock Chess runs factor 3 and colossus chess4 runs factor 5 faster.

In the game Superconny vs. Superstar36K the Novag machine was ahead in the game, but then superstar found a draw line by giving endlessly checks with the queen.

Fidelity had to play Chafitz Steinitz and for a long time it looked like Chafitz Steinitz could win the game. The opening Orang Utang was maybe not optimal for the fidelity machine.

we can see it as a nice surprise that the einstein chess wizard won against frans morschs Mondial II:
For me, all about 18 Nxc6. It lead to a king attack, but not a strong enough one - and when it failed, too much had been sacrificed to save the game going forward. Reminded me of Chris playing against Komodo at CCC with knight odds a short while ago.

Wow! I might come back and have a closer look at that game, but just watching it played through, it didn't look like a computer v computer game at all!

Looking at it again, I feel that Ron got lucky: there were several points at which the attack against Frans' king would have failed if pieces hadn't been in just the right place - and if the attack had failed, then Frans would have mated Ron.

Rons einstein is a miracle. It runs for years now on 2 batteries. I play 40/120 games. Thats many hours. I have no explanation for this. Maybe there is a hidden solar cell or it is a 4 bit cpu without power waste.

I've hosted your table to make it more readable - link.
Surprised that Chafitz is leading the pack? I'd expect it to be in the bottom half!

The next game is between rebell mystery modul and mephisto MMII HG240.
It should be known that the different programs (Ed schroeder prototype amsterdam, selective AB program) (ulf rathsmann brute force A program) run on the same pcb. A 3.7 mhz 6502 with only 32 kb rom and 4 kb ram. Difficult for a knowledge program only to have 4 kb ram.

Why did Ed make a module called "Mystery"?

No he never gave it this name. The people bought it and wondered: what is this. Because it was a non labelled mm2 pcb. But it played different and was obviously not a rathsmann program. So they gave it the name rebel mystery.
Later then it was clear that this was the module ed schroeder used in amateur group in amsterdam 1985. At this time rebel was not so strong. Due to the fact that 4 KB were not enough. So the later rebel5.0 module that came after the cologne championship 1986 had 8 KB Ram and also 5 mhz.
So the correct name is maybe rebel amsterdam.

That's because people gave it that name, not me
In the beginning (still amateurs) Frans Morsch and I worked a lot together, letters, meetings, phone calls. The program contained the engine from Frans Morsch and the interface of mine. It was meant to be released by Hegener & Glaser but it never came that far. How that version became into the public domain is the real mystery here

You have that wrong, the REBEL Amsterdam 1985 version was never released, never made it to Munich. Frans played with his NONA. I believe he won the Amateur Group. At that time NONA was definitely stronger than REBEL.

No it was never released. But you once sold it together with the portorose version. I could replay the games from amsterdam with the version i have here.
Yes. IMO you were not finished bringing your bigger engine into the limited resources of the pcb.
