"The Mephisto Expendables Tourney, TMET"
The time machine, 25-35 years later!
"With the knowledge we have today we know many things much better"
TMET started April 15th, 2018

Of course, with the flag of The Netherlands (Ed Schroeder, Frans Morsch) and the German flag (Mephisto and German programmers).
Assorted colors for different chess computers? Or sets of pieces become confused!
Sure, Mephisto Polgar in "pink" and Mephisto Magellan as strongest chess computer in "black".

A little story

Since October 2017 I try to collect a group of interesting older Mephisto chess computers for an endless tournament.

At this time, I had a lot of contacts to very friendly peoples from chess computer community (most are Germans), examples: Werner Eberl, Andreas Mühlbradt, Eduard Miller, Peter Haupert, Reinhard Sacher, Gerd Klappich, Ruud Martin and much others. Most important my contact to Gerd Klappich. Gerd tuned 15 of 20 of my chess computer for my new idea. I had a lot of fun with him. Andreas and Ruud gave there helps for tuning. From Andreas is the "Display-VOLT" module idea. Carsten Meyer do a lot in questions of tuning and gave the community an immense help.

If you need a person for tuning - with excellent technical understandings and knowledge - please contact me. I will send your request to Gerd if you like (if he have time for it).

I have most interest on Mephisto Modular boards. The Exclusive / München wooden boards needs to many places. The modular board technique is perfect if I must have switched defect parts. Even though they were pioneers 25-35 years ago yet. In this contest it is also interesting to note the Super Mondial's (Versions: 1a, 1b by Frans Morsch, v2 and Mega IV by Ed Schröder & the Dallas program 68000 XL by Richard Lang). I like the Mephisto laptop series also (Versions: Modena, Milano Pro / Master Chess, Atlanta by Frans Morsch, Milano / Nigel Short by Ed Schröder and Berlin 68000 / Berlin 68020 by Richard Lang).

So, I have collected best material to perfect conditions. 2x Mirage type 1, 5x Modular type 2 & 4x Modular type 4 boards, so each of the modules can be run under an own board. The type of Modular board is important in questions of 5 / 6 volt. For an example: Newer modules need a type 4 board (Portorose / Lyon / Vancouver / MMVI / Senator / Magellan and tuned modules often). In additional I collect different Mondials and chess computer from the Laptop series.

Back to Mephisto Modular: Mephisto Modular (German WIKI)
Type 1 with ~ 6.20 volt, type 2 with ~ 5.80 volt, type 4 with ~ 5.00 volt)

Better as the older original power adapter HGN 5001 or others from Mephisto / Saitek are in my humble opinion:

Hint 1: goobay 59031, 3-12V x 600mA = max. 7.2W (example: 9V x 600mA = 5,4W)
Hint 2: Ansmann APS600, 3-12V x 600mA = max. 7.2W
Hint 3: Leicke NT03091, 9V x 1A (1000mA) = 9W

Hint 4: I am using for pieces 1mm felt (Filz in German) and Olfa Kreisschneider für Kreise von 1-15cm DM (link to Amazon)

Why I do that?
From time to time I have to switch to another part of computer chess, can be an older part. I am buying and selling chess computers since I was 11 years old. More as 80 chess computers I had in my possession since 1978: My first was a Chess Challenger 7. Now I am 51 years old. I am sure I have a lot of fun to play myself vs. all the older Mephisto chess computer. So, after FEOBOS I will start the endless tournament. If I have time for it, new games can be play. Games and tournament table will be public here / on my site, why not?!

Maybe our FEOBOS opening book will be in the future available for a newer chess computer? Sure, that a lot of people will have many funs with all the work around FEOBOS by Klaus Wlotzka and myself in combination with newer and stronger chess computers.

Please Note:
Of course, my collection of Mephisto chess computers isn't complete! I the past I have much technical problems with a Mephisto Risc 2Mb module set by Ed Schröder. So I have no interest to buy it again for TMET. The modules by Richard Land are very expensive. I have Mephisto Portorose 16bit, tuned to Mephisto Vancouver 16bit. This is enough. Mephisto Atlanta is the same as Mephisto Magellan. The different from Mephisto Berlin 68000 / 68020 to Mephisto Vancouver module are very small. Mephisto produced a lot more chess computers but I am thinking I have a strong group for TMET collected. Again, I have no interest to add older chess computers from Novag, Fidelity, Saitek, CXG, Excalibur and others.

TMET started with 14 participants at April 15th, 2018.

Ed Schröder, Frans Morsch, Richard Lang, Ulf Rathsman, Thomas Nitsche, Elmar Henne ...
made the Mephisto chess computer fans very happy!
I like most the programs by Ed Schröder!

So Ed Schröder get my personal computer chess award!
5 chess computers with programs by Ed are included in TMET!

Have a look here: http://rebel13.nl/dedicated/overview.html (nice work by Ed himself)

Gerd Klappich, Andreas Mühlbradt, Carsten Meyer for his sensational work & Ruud Martin
... the chief persons in tunings at this time ...
get the Chess Award also!

Older chess computers / Participants

Note:
Click to enlarge on the pics (from 512 x 288 to 1536 x 864)!

Mirage Board 1 / Mirage Board 2 (Type 1)

Mephisto starts to produce modules around 1983 / 1984!
Programmers of Mirage & MM I modules are Thomas Nitsche & Elmar Henne (Germany)
MM I tuned with HG170 opening eprom.

The pieces comes from a Modular board. Looks perfect for me.

Gerd Klappich produced a VOLT module for myself. For all the different modules and boards I need it for testing.
Around 6.21 volt for type 1!

A feature:
You can operate the Rebell 5.0 module with sensors in Mirage board!!
Mirage board works fine with all functions with: Mirage, MM I & "NON TUNED" Rebell 5.0 modules!
More information (*.pdf)

One year later in 1985 B&P and MM IIa modules are available!

Modular Board 3 (Type 2)

Programmer of B&P is Ulf Rathsman (Germany)
A bit better in tactics as MM IIa and in endgame weaker.

At the moment B&P still in tuning from 3,7 to 7,4MHz.
Around 5.87 volt for type 2!
PICs follow later!

Modular Board 4 (Type 4)
Participant 01 of 14

Programmer of MM IIa is Ulf Rathsman (Germany)
MM IIa tuned with HG240 opening eprom and from 3,7 to 7,4MHz
With Polgar my personal favorite from all of the Mephisto chess computers I have!
Very strong after tuning ... go MM IIa go ...
I have many fun with MM IIa since I have it.

In 1986 Rebell 5.0 module and Super Mondial Ia / Ib are available!

Modular Board 5 (Type 2)
Participant 02 of 14

Programmer of Rebell 5.0 is Ed Schröder (The Netherlands)
Rebell 5.0 is tuned from 5 to 8,8MHz.
Tactically often very danger, good for a surprise during the games.

Programmer of Super Mondial Ia is Frans Morsch (The Netherlands).
Super Mondial 1a is tuned from 4 to 8MHz with Super Mondial 1b eprom.
The playing style is unknown for me, can be a newer version of the CXG Sphinx Dominator program?!

Programmer of Super Mondial Ib is Frans Morsch (The Netherlands).
Programmer of Mega IV from 1988 is Ed Schröder (The Netherlands).
Super Mondial 1b is tuned from 4 to 10MHz with Mega IV eprom.
Mega IV can be an improved MM IV program!?

In 1987 MM IV module and Super Mondial II are available!

Modular Board 6 (Type 4)

Programmer of MM IV is Ed Schröder (The Netherlands)
MM IV tuned with HG440 opening eprom and from 5 to 10MHz.
v7.1 (two versions are available)
Lesser tactic, playing style is designed more positionally.

Programmer of Super Mondial II is Ed Schröder (The Netherlands).
Super Mondial II is tuned from 4 to 8MHz.
I think the playing style is comparable with MM IV.

Most interesting for tuning is Super Mondial 1b & Super Mondial 2.
Super Mondial II was available with and without a "Collage" module (positions for chess training)!
Ordinary, Super Mondial II with College module has for each field coordinates on the board. I changed here the surface.

In 1989 Roma II and Polgar modules are available!

Modular Board 7 (Type 2)
Participant 03 of 14

Programmer of Roma II is Richard Lang (England)
Roma II tuned from 10 to 20MHz, running on 68000 Motorola processor.
Positionally playing style, often better as the others currently in endgames.

Modular Board 8 (Type 2)
Participant 04 of 14

Programmer of Polgar is Ed Schröder (The Netherlands)
Polgar tuned from 5 to 10MHz with a nice OLED in yellow color.
v1.5 (two versions are available)
A mix from positional and tactically playing style, better in endgames as the other modules by Ed.
Polgar is running on type 2 Modular with 5,76 volt for an example!

With an OLED display in yellow!
Maybe with MM V the most popular Mephisto modules.

Modular Board 9 (Type 2)
Participant 05 of 14

In the year 1990 the MM V was available.
Programmer of MM V is Ed Schröder (The Netherlands).
MM V tuned with HG550 opening eprom and from 5 to 10MHz.
v5.1 (two versions are available)
Tactical playing style, maybe the strongest 8bit chess computer together?
Or is the strongest the Nigel Short eprom inside Milano?

In 1991 Vancouver module and Milano are available!

Modular Board 10 (Type 4)
Participant 06 of 14

In the year 1991 the Vancouver module set was available.
Programmer of Vancouver is Richard Lang (England).
My Mephisto Portorose 68000 from 1989 is tuned with Vancouver eprom and an OLED display.
Balanced playing style and stronger for endgames.

Around 4.98 volt for type 4!
So I don't need the adapter module for a type 4 Modular board.

Participant 07 of 14

In the year 1991 the Milano was available.
Programmer of Milano is Ed Schröder (The Netherlands).
My first Milano is tuned from 5 to 10MHz and has a blue display.
An improved Polgar program?

Here with a wooden board from Spain and nice pieces with king size 60mm for analyzes.
In background a DGT-3000 chess clock. I like more the good and old mechanic chess clocks.

Participant 08 of 14

In the year 1992 the Modena was available.
Programmer of Modena is Frans Morsch (The Netherlands).
Modena is tuned from 4 to 8,4MHz.
Same program years before was available in CXG Sphinx Dominator.
Tactical playing style with problems in endgames.

An underestimated chess computer. Unfortunately, with some missed features for problem solving.
No underpromotion for an example! The underpromotion problem can be found in all the chess computers by Frans Morsch.

The same figures as the original but in wooden color from a Fidelity chess computer!

Participant 09 of 14
John Stanback (USA) released in the year 1992 the program Zarkov 2.61 for PC, in the year 1995 the version Zarkov 3.04.
At first I am thinking Zarkov 2.61 is a good idea for TMET, but it seems Zarkov 2.61 isn't stronger on Intel® Pentium® Processor with MMX™ Technology 166MHz Notebook as ~ 1800 Elo with 60 moves in 15 minutes. I have interest to simulate ~ 2100 Elo for a Zarkov version.

A more powerful Zarkov needed!

Zarkov 3.04 on Intel® Pentium® Processor with MMX™ Technology 166MHz = ~ 1.000 nodes per second!
Zarkov 3.04 on Intel® Core™ i7 Processor 5930k 4.0GHz with Chess-DOS-VirtualMachine = ~ 22.000 nodes per second!

Chess-DOS-VirtualMachine (idea by Franz Huber)

Have a look in the following graphic (307803 : 14 seconds = 21.985 nodes per second)!
The Chess-DOS-VirtualMachine on Intel® Core™ i7 Processor 5930k 4.0GHz is ~ 22 times faster as Zarkov 3.04 on Intel® Pentium® Processor with MMX™ Technology 166MHz with MS DOS 6.22.
= Factor 4,5 or ~ 300 Elo stronger without ponder!

I am sure that Zarkov 3.04 is playing with ~ 2100 Elo with time control "60 moves in 15 minutes" on Intel® Core™ i7 Processor 5930k 4.0GHz with Chess-DOS-VirtualMachine and without ponder!

Settings:
Playing Strength = Master, Playing Style = Active, Think on opponents time (Permanent Brain) = Off, Selective Search = On, Transposition Table (Hash) = On

The playing style of programs by John Stanback is absolutely human like.

Participant 10 of 14 (Nigel Short)
In the year 1993 the Nigel Short version for Milano was available.
Programmer of Milano / Nigel Short is Ed Schröder (The Netherlands).
My second Milano is tuned with Nigel Short eprom, from 5 to 10MHz and has a yellow display.
The Nigel Short program is a good mix between MM V and Polgar in playing style.
The last and maybe the most interesting 8bit program by Ed Schröder!?

With a display in yellow and same figures as the original but in white from Peri!
Pieces can be found in "Travellers Club Collection" also.
The same white comparable to the Mephisto Modular figures!!

Participant 11 of 14

In the year 1996 the Milano Pro was available.
Programmer of Milano Pro is Frans Morsch (The Netherlands).
My Milano Pro is tuned from 20 to 28,4MHz.
The Milano Pro has the same program as Senator (without RAM for hash).
Atlanta (Laptop series) and Magellan module are the more expensive chess computers (with RAM for Hash).
It can be interesting to have both in my tournament (Milano Pro without RAM and a Magellan with RAM).
Please have a look in my further comments to the next participant Magellan.

Silver figures comes from Mephisto Milano!
Black shiny figures comes from "unknown" ... maybe a Fidelity chess computer?

Modular Board 11 (Type 4)
Participant 12 of 14

And the chess computer community are waiting many years for new module.
In 1998 Saitek comes with different new modules (MM VI / Senator / Magellan).
Programmer of these modules are Frans Morsch (The Netherlands)

In my opinion is Magellan / Atlanta the most interesting older chess computer together with Novag Diamond series & Mach III & Mach IV!
The Magellan produced from human perception a fantastic aggressive style of chess.

The Modular board for Mephisto Magellan have a black border, it's rarely!

Ruud Martin tuned my Senator with a 512kB memory ... so a Magellan was born!

Participant 13 of 14

Millennium released in 2015 Chess Genius and in 2016 Chess Genius Pro.
Programmer is Richard Lang (England).
Chess Genius is running with an ARM Cortex M4 with 48MHz, Chess Genius Pro with an ARM Cortex with 120MHz.
I dislike the display and pieces and changed that.
For my tourney I will used Chess Genius only because Chess Genius Pro is too strong for TMET.
So many years later I await a better quality. But the price is fully OK and I like it.

Figures comes from Mephisto Modena!

Participant 14 of 14
Frank Quisinsky (of course, I have interest to play).

I am playing on my wooden boards 1 & 2 vs. all the chess computers.
I have more fun with original Garde Ruhla clocks in comparing to my DGT3000 chess clock.
Here two Ruhla clocks from 1981 and 1987 made in GDR!
On the left site a chess board from Spain with DGT Polgar pieces (king size 95mm).
On the right site chess board and pieces from India (king size 90mm).

Chess boards & pieces are from my chess dealer: Schach Niggemann
