A little story

From October 2017 - June 2018 I collected a group of the older Mephisto / Novag chess computers for a 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 10 of 20 of my chess computer, Andreas tuned 2 of 20 and Ruud 1 of 20 for my new idea. I had a lot of fun with Gerd, Eduard and the other I mentioned. 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 tunings - with excellent technical understandings and knowledge - please contact me. I will send your request to Gerd if you like.

I have most interest on Mephisto Modular boards. The Exclusive / München / Bavaria wooden boards needs to many places. The modular board technique is perfect if I have to switched defect parts. Most collectors have an other opinion, wooden boards are in the community more popular.

One of the last Mephisto Exclusive boards (type 4) by Hegener & Glaser with serial number 0789502.
In my opinion fully enough to have one of such boards.

 

In this contest it is also important to note the Mephisto laptop series (Modena, Milano Pro / Master Chess & Atlanta by Frans Morsch, Milano & Nigel Short by Ed Schröder and Berlin 68000 & Berlin 68020 by Richard Lang). I like it a lot and collected 4 chess computer from the Laptop series.

So, I have collected best material to perfect conditions. 1x Exclusive type 4, 1x Mirage type 1, 4x Modular type 2 & 5x Modular type 4 boards. Each of the modules can be run under an own board. The type of Mirage / Modular / Exclusive boards is important in questions of 5 / 6 volt. For an example: Newer modules need a type 4 board (Portorose / Lyon / Vancouver / MM VI / Senator / Magellan and tuned modules often). After I am looking for Mephisto chess computers I collected 4 Novag chess computers I like a lot (Zircon II, Obsidian, Diamond I & Star Diamond).

Back to Mephisto Modular: Mephisto Modular (German WIKI)
Type 1 (Mirage board) with ~ 6.20 - 6.40 volt, type 2 (Modular board) with ~ 5.80 - 6.00 volt, type 4 (Modular board) with ~ 5.00 volt.

Better as the older original power adapter HGN 5001 (8 volt) or HGN 5009 from Mephisto / Saitek (9 volt) are in my humble opinion:

Hint 1: goobay 59031, 3-12V x 600mA = max. 7.2W, can be used for all modules.
Hint 2: Ansmann APS600, 3-12V x 600mA = max. 7.2W, can be used for all modules.
Example: 9V x 600mA = 5,4W

Hint 1 & 2 can be used for Novag chess computers also (polarity switch possible) or as a replacement for HGN 5004a.

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)

Cleaning, felt tool from OLFA, goobay power adapter ... I need it.

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 different chess computers I had in my possession 1978 - 2010. 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 & Novag chess computer. So, after FEOBOS I started TMET. 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.

Note:
Of course, my collection of Mephisto chess computers isn't complete! The modules by Richard Lang are very expensive. I have Mephisto Portorose 16bit, tuned to Mephisto Vancouver 16bit. This is enough. 32bit module sets (68020 / 68030 processors) are unessintial stronger. Mephisto Atlanta is the same as Mephisto Magellan. The differents from Mephisto Berlin 68000 / 68020 to Mephisto Vancouver modules are very small. Mephisto produced a lot more chess computers but I am thinking my collected group of Mephisto chess computers are good enough for TMET.

Included in TMET, the old Novag Diamond I by David Kittinger. I like the black chassis / case much more as the grey chassis for the successors Novag Diamond II, Novag Star Diamond.

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

Mephisto Modular boards, I like it so much!

 

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

 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)

And David Kittinger ...
for all the nice Novag chess computers can hold the symbolic Chess Award in his hand. 

Gerd Klappich, Andreas Mühlbradt, Carsten Meyer, Ruud Martin
for his sensational work in questions of tuning

get the symbolic Chess Award also!

Chess computers / Participants

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

 

Mirage Board (type 1) / Modular Board 01 (type 2) / Modular Board 02 (type 2)

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.

Gerd Klappich produced a VOLT module for myself (idea by Andreas Mühlbradt).
That's interesting for test power adpaters, Modular / Exclusive boards & modules.
I added for each Modular board a pic with and without volt information!

Mephisto Mirage module and Mirage board with the better Modular pieces and a display module.
With Mirage board Mirage, MM I & Rebell 5.0 modules works fine with pressure sensor!

Mirage & MM I are not strong enough for TMET with around 1300 - 1400 Elo.

 

Modular Board 03 (Type 4)
Participant 01 of 14

One year later in 1985 the module MM II is available.
Programmer of MM II is Ulf Rathsman (Germany)
My MM IIa is 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 was available!

Modular Board 04 (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.
Sometimes tactically danger, good for a surprise during a game.

 

In 1987 MM IV module was available!

Modular Board 05 (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, first = v6.0)
Lesser tactic, playing style is designed more positionally.

MM IV will not participant for TMET, enough programs by Ed Schröder participant.

 

In 1989 Roma II and Polgar modules are available!
This year released Novag the Super VIP also.

Modular Board 06 (Type 4)
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 other chess computers at this time in endgames.

 

Modular Board 07 (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.

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

 

Modular Board 08 (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, first = v5.0)
Tactical playing style, with Nigel Short (eprom inside Milano) the strongest 8bit chess computer together!?

 

In 1991 Vancouver module and Milano are available!

Modular Board 09 (Type 4)
Participant 06 of 14

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 with a strong endgame.

Around 4.97 volt for type 4!
So I don't need the adapter module for a type 4 Modular board.

 

Participant 07 of 14

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 my "Chess Board 4" from Spain. A magassar ebony board with maple / boxwood triple weighted pieces (king size 60mm, pieces are rarely) for analyzes.
In background a DGT-3000 chess clock. I like more the good and old mechanic chess clocks (Rhula, GARDE).

I like it a lot?
An older interesting plastic chess computer and in additional a nice wooden chess board.

 

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.
Years before, the same program was available in CXG Sphinx Dominator.
Tactical playing style with problems in endgames.

An underestimated chess computer!

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

 

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 the same pieces as the original but in white from Peri (1959-2004).

Peri Pic 1: I found my Peri boards after a long search over months in ebay.
Without magnets such pieces are available in "CTC Travellers Club Collection" also!
Peri Pic 2: Very rarely is the third Peri board from my collection.
Again the same pieces but in white and black shiny colors.

The three boards are from the years 1977 / 1978 !! 

Mephisto Milano: A great chess computer to a favorable price.

 

Novag Diamond I: Participant 09 of 14
Novag Zircon II: Participant "out of competition"

In 1994 the Novag Diamond I / Novag Zircon II released.
Programmer is David Kittinger (USA).
Playing style Novag Diamond I: Technically a good chess computer and very smart tactically! The weaknesses are the strategic skills and the endgame. I believe for Dave the tactical strength was certainly in the foreground. Maybe tactically a bit more aggressive as the successor Star Diamond?! However the Star Diamond plays more balanced over all playing phases.
Playing style Novag Zircon II: The typical materialistic chess computer but strong. Tactically more unspectacular as Diamond I but _now and then_ Zircon II surprised with nice attacking moves if many pieces are on the board. The opening book isn't good.

Novag plastic pieces are terrible, I don't like it.
Novag Diamond I with Mephisto Modular 60mm pieces, Novag Zircon II with the smaller Peri 50mm pieces in the same clear white color!

Two different Diamonds I & Zircon II are available!
I have the first versions from both (the second versions are running with 26,6Mhz)

Zircon II & Diamond I = Two BIG brothers!

Diamond I 9303, handbook from the year 1994, Serial: 11668
H8 RISC processor with 20Mhz.
64K Byte ROM, 129K Byte RAM, Hash 118k Byte, Opening Book Size > 36.000

Zircon II 9403, handbook from the year 1994, Serial: 50713
H8 RISC processor with 20Mhz.
32K Byte ROM, 1K Byte RAM, Hash -k Byte, Opening Book Size > 13.000

ROM = Read Only Memory
RAM = Random Access Memory

The Diamond I (~ 1975 - 2000 Elo) is with hashtables around 75-100 Elo stronger as Zircon II ( ~ 1900 - 1925 Elo)!

I will used the Novag Obsidian for TMET out of competition or later.

 

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 a Peri board!

Here a pic from all the different colors of the very nice 50mm pieces.
I believe the Mephisto / Fidelity pieces comes at first from Peri but I am not to 100% sure.

Field a8 / a6: From Peri boards (white shiny)
Field b8 / b6: From Peri boards, same color as the larger 60mm Mephisto Modular pieces
Field c8 / c6: From Mephisto Modena / Milano / Mondial 68000 XL, Kishon Chesster
Field d8 / d6: From Mephisto Mirage, Europa, the different Mondial versions
Field e8 / e6: From Mephisto Milano / Berlin
Field f8 / f6: From a Peri board & different Fidelity computers (nice for a wooden board, to see on the pic)
Field g8 / g6: From a Peri board (black shiny)
Field h8 / h6: Standard black pieces

My favorits are for white b8 / b6 & c8 / c6 and for black g8 / g6.

Fidelity used reddish-brown and I believe dark-brown (don't have it).
All in one: 10 different colors of these pieces are available.
The color reddish-brown isn't nice for me.

Animal Equality (zur Verteidigung aller Tiere, in English: Defence of all animals ... VEGAN)
Not means the chess knights :-)
A sticker on my Notebook only.

 

Modular Board 10 (Type 4)
Participant 12 of 14

And the chess computer community are waiting many years for a new module.
In 1998 Saitek released three 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 "out of competition"

In 2003 the Novag Star Diamond released.
Programmer is David Kittinger (USA).
Playing style: Tactically very strong, very balanced over all playing phases. Really the perfect chess computer for club players. In my humble opinion the most interesting chess computer ever.

Sure, with Mephisto Modular pieces!

After my information two different Star Diamonds are available!
I have the second version!
The first version is running with a 16bit H8S/2312 processor with 25MHz.

Star Diamond 1004, handbook from the year 2002, Serial: 73448
SH7020 RISC processor with 20Mhz (32bit processor).
1M Byte ROM, 256K Byte RAM, Hash 118k Byte, Opening Book Size > 200.000

I will used the Novag Star Diamond for TMET out of competition or later.

 

Participant "out of competition"

In 2005 the Novag Obsidian released.
Programmer is David Kittinger (USA).
Playing style: The same as Novag Zircon II _11 years later_ but the processor is ~ 15% faster.
I believe that in many of Novag chess computers to 95% the same program is included: Citrine, Star Ruby, Jade II, Aquamarine RISC II, Emerald Classic Plus, others!
I like the design from Zircon II and Obsidian much more as from the others.

The Obsidian was available with very nice wooden pieces.
Have a look on the second pic. You can see Novag Zircon II with Peri pieces in background. I added ultra strong Neodym N52 magnets on the pieces.
This pieces are working fine for Mephisto Laptop series or Novag Zircon II, but the Obsidian or Mephisto Mondial's have ultra sensetive sensors and N52 magnets are to strong.

Obsidian 1016, handbook from the year 2005, Serial: 135509
H8/3214 RISC processor with 2x 16Mhz.
32KByte ROM, 1KByte RAM, Opening Book Size > 8.900

 

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 to strong for TMET.
So many years later I await a better quality. But the price is fully OK and yes ... I like it!

Figures comes from Mephisto Modena / Milano!

 

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

I am playing on my chess boards 1-3 vs. all the chess computers. Sure that with good material the own Elo can be 5 points higher :-)
I have more fun with original Garde Ruhla clocks in comparing to my DGT3000 chess clock.
Here two Ruhla clocks from 1981 and 1982 made in GDR!

Most of my chess boards & pieces are from my chess dealer: Schach Niggemann

     

Chess Board 1 & 2
On the right site chess board in bird's eye maple / ebony and double weighted pieces from India in high quality booxwood / sheesam (king size 95mm).
On the left site a anigre chess board from Spain with double weighted DGT Polgar pieces in high quality boxwood (king size 95mm).

My Chess Board 3 is a for me interesting because it's a perfect wood combination!
The spanish board in mahogany and the pieces 76mm double weighted in teak / boxwood from "Weible" (Jubilee edition).

*1 = In 98% of the cases pawns are promoted to queens. Sometimes though, it would be better to promote to something else other than a queen, like in the example Pos. 3!
*2 = Mill. Chess Genius / Genius Pro aren't easy to test. The clock is still running after mate found. Computer doesn't abort the analyses. Solving time can vary with 1-2 seconds!
*3 = No underpromotion!
*4 = It seems Novag Obsidian & Novag Zircon II is to 95% the same program but the processor from Novag Obsidian is 15% faster.
*5 = It seems Novag Star Diamond is in most of cases 50% faster as Novag Diamond I.
*6 = Mephisto Modena can't display / show mate in x moves! Measured if 9,99!
