INITIAL ACTIVATION
Congratulations on your new Mephisto Phoenix chess computer. You have acquired
the most powerful chess computer ever produced in series. The Mephisto Phoenix
is a UCI-based chess computer that runs many different chess programs (so-
called engines). In addition, it offers the possibility to emulate classic
chess computers as well as to play online directly against other people on
Lichess.org. To thoroughly enjoy the device, we ask for a few minutes of your
attention to familiarize you with the special features of this complex system.
This manual is primarily intended to describe the system logic and its basic
functions. Since the system is set up to receive regular updates, we regularly
add new features to our website at https://computerchess.com/mephisto-
phoenix/#faq .
Connection of components
Connecting the board
First, connect the chessboard by attaching the Mini-Din connector to both the
board and the back of the computer module. Make sure that the arrow on the
cable is pointing upwards and insert the cable firmly into the respective
connections. Be careful not to bend the pins.
The Mephisto Phoenix is compatible with all chess boards of the Millennium
Exclusive and Supreme Tournament series.
Connect power supply
Now plug the power adapter into the appliance and connect the power adapter to
your socket.
Controls on the device
On the front of the device you will find a 7″ touch screen, via which you can
control its various functions.On the back you will find the USB port (for connecting
USB flash drives for updates or PGN exports), the port for the chessboard, the
power socket, the ON/off switch, the control led and the reset button.
Switch on
Toggle the switch on the back to I to start up the device.
The MEPHISTO lettering appears briefly on the display. Note that the system
will take about 30 seconds to start.
The control LED turns on in about 20 seconds after flipping the switch, it
indicates that the firmware of the chess computer has been loaded.
When the main menu appears with the mode selection, the system is ready for
operation.
Manage the most important initial settings
Set Language
The language selection appears automatically at the first start of the
Mephisto Phoenix: Confirm the desired system language.
You can choose between English, German, French, Dutch and Spanish.
You can also find the settings for the system language in the “PLAY AGAINST
COMPUTER” mode under SYS SETT / LANGUA.
SYS SETT – main system settings
The system settings of the Mephisto Phoenix can be found in “PLAY AGAINST
COMPUTER” mode under the SYS SETT button, at the bottom right of the display:
Determine board orientation (BOARD)
Indicate whether the cable leads away from your chessboard to the right or to
the left. Under SYS SETT / BOARD you can change this. If the cable leads to
the right (you are sitting in front of the logo badge), then the LED on the
BOARD button must light up. If the cable leads away to the left, tap the
button once.
Turn on WiFi (WIFI)
Turn on the WiFi in the device to check for system updates. You can find the
settings under SYS SETT / WIFI. For more details on connecting to a WiFi
network, see page 17.
Check for updates (UPDATE)
Check if there are system updates for your chess computer. After you have
successfully connected the WiFi, press UPDATE under SYS SETT to start the
update process. See page 17 for more details.
Select the latest version (SELECT VERSIO)
If updates have been found and installed for your system, you must now select
the latest version. Under SYS SETT, press SELECT VERSIO, confirm with CONFIRM,
and confirm again with CONFIRM (the system displays the current version in the
status box). The system now restarts with the latest version. See page 17 for
more details.
Starting a game now
You can now start your first game with the Mephisto Phoenix. To do this, the
board must be connected to the computer.
If not already done, select “PLAY AGAINST COMPUTER” mode, or exit the system
settings so that you can see the chessboard display on the control screen.
Now please set up the pieces in their initial position.
The computer is now ready to play with its default settings. First, however,
please select a suitable game profile.
In the example, we now start with the adaptive SHREDDER mode, which also shows
you your own ELO rating.
To do this, press COMF MENU (COMFORT MENU) and select the SHREDDER chess
engine in the top row. The selection is indicated by a blue LED. Now select
the last profile “Adaptive”, the selection is confirmed again with the blue
LED.
Now press LOAD PROF (LOAD PROFILE) to preview the profile parameters. Confirm
this with CONFIRM. You now start a game against the
Engine Shredder in adaptive mode. This mode starts at 1400 ELO and changes its
ranking depending on the win or loss of the game. After a few games, you will
always have an equal opponent with this mode and can easily track your
development based on your ELO rating.
Main tips for operation
In the following, we would like to give you a few tips on the key operating
logics of the system.
Which parameters are loaded automatically when the system is restarted?
After a restart of the system, the general system settings, as last used
outside the profiles, are reloaded, the socalled “Profile 0”. Theseinclude the
SYSTEM SETTINGS (volume,led settings, etc.) in particular, but also the most
recently used engine, the configuration of theanalysis box, the configuration
of the opening books and the selected time setting. All engine-specific
parameters, the so-called UCI settings, are NOT loaded automatically. For
example, the ELO setting as well as specific engine options such as “Use NNUE”
or “Skill Level”.
Also, the settings that you may have used by loading a profile in the previous
session will NOT be loaded automatically.
TIP: If you want to play regularly with consistent settings, we recommend that
you save them in a profile in the COMFORT MENU and load them immediately after
starting the system.
For this purpose, the COMFORT MENU “remembers” which profile you last used and
highlights this in grey.
Changing settings during a game
If you change settings during a running game, please note that some settings
can only be activated with the next “New Game” command. These include, in
particular, settings ith a significant influence on the playing strength,
such as the ELO limitation of the engine. If you are not sure whether the
changes made are immediately active, select COMF menu / SHOW ACTV to view the
current settings. Parameters marked with an ” * ” will not be activated until
the next new game. See also page 11 How do I get back to the main menu?
To return to the main menu, i.e. to select the operating modes of the chess
computer, proceed as follows:
- From the PLAY AGAINST COMPUTER mode, press HOME a second time in the control screen. The button changes to MENU, press again to return the main menu.
- From the emulations by pressing the MEN key (bottom left) in an emulation.
Meaning of the status LEDs in the buttons
The blue status LEDs in the buttons usually mean “ON” (blue) or “OFF” (grey).
An exception is the COMFORT MENU, where the blue LED marks the selected
profile, hich is loaded with LOAD PROFILE.
Software version
This manual is based on software version V3.55E, as of August 2022. Due to
permanent improvements to the system, details can deviate from the procedure
described here. For detailed descriptions of individual functions, please see
our FAQ at https://computerchess.com/mephisto-phoenix/#faq .
OPERATION MODES
Main menu
In the main menu, select how you want to use the chess computer. The offered
modes depend on which software licenses have been purchased for your device.
“PLAY AGAINST COMPUTER” MODE
This is the main operating mode of the chess computer. Here you can play
against various chess programs, analyze or play in 2-player mode. You can also
find the system settings such as volume, WiFi, the led control of the board,
etc., here.

18: Notations| Shows the last 8 moves of the game.
19: Analysis-Box| Displays various evaluations of the engine for the current
gameplay. You can
configure these via the display settings.
Special features of the rating bar
The ratings bar shows you the current position rating of the active engine.
The way it works depends heavily on the engine used. Classical chess programs
usually evaluate on the basis of point value. If the white bar is a box above
the center mark, white is better by a value of one point. Neural engines, so-
called NNUE engines, on the other hand, evaluate according to the probability
of victory. Another special feature can be very weak playing strengths, such
as the Play&Win profile in Komodo 14.1. Komodo uses the position evaluation in
such a way that it evaluates itself significantly more strongly than it
actually stands, in order to sacrifice material more willingly. The display of
the rating bar will therefore work completely differently depending on the
engine and profile or settings of the engine.
In the example, Komodo gives itself a score of +9.99, so it thinks to be much
stronger than it actually is. The position has the same material strength for
both sides, so it is actually balanced. Komodo uses this on very low levels to
handle their own material more “carelessly” and give the player a chance to
beat it.
Views of the Analysis Box
Depending on the configuration, you will find the following information in the
analysis box.
Main variant
The main variant indicates how the engine suspects the game will continue. It
is preceded by the current move number. The main variant is ideal for training
with engines. You can switch them on and off via CHESS SETTIN / display SETTIN
/ MAIN.
Position assessment
In the first line after the main variant you will find the position
evaluation, the value corresponds to the ratings bar. Please also note the
special features of the ratings bar on page 9.
Last move time
In the second line after the main variant you will find the time required for
the last completed move.
Calculation Depth
In line 3 you will find the calculation depth, divided in half, possibly
depending on the engine, into minimum search depth (which applies to the
complete development of the game) and a peak depth, which applies to
individual, further recalculated variants.
Current reflection time of the moving side
In line 4 you will first find the current reflection time of the player who is
moving.
AST (last move examined)
After the reflection period, the indication of the last move examined and the
number of the sequence follow. In the example, the move “branch”, which starts
with g8-h8, was examined as second.
Calculated positions
The branch is followed by the number of calculated positions per second
(number of calculated nodes until the current main variant has been found),
followed by the number of calculated positions for the entire move (number of
nodes per second).
Line 4 can be switched on and off via CHSS / SETT /display SETTIN/ EXPERT.
The HINT Option
If HINT is disabled, a “—-” appears in the expected game development instead
of the expected countermove.
TIP: This is only the case if “Ponder” is switched on. This option is
intended for users who deliberately do not want to see the direct expectation
of the computer and want to use the maximum playing strength of the system
(Ponder active).
COMF MENU – Profile selection, quick selection of the engine and its
settings
General Information
For the Komodo, Shredder and Hiarcs engines, you can easily access predefined
profiles via the Comfort menu.
Profiles combine a variety of general and engine-specific settings, so you can
quickly adjust many settings at once.
General settings are, for example, the engine, the time setting, CPU speed,
the displays in the analysis box and the settings of the opening book. Engine-
specific settings vary from engine to engine. Typically, these are ELO or
skill levels, the use of NNUE networks, the number of threads, hash size and
pondering (engine calculates even when it’s your turn).
The stored profiles were defined by the Mephisto Phoenix development team in
such a way that there is a suitable “level” for each player type. Special
features of the respective engines are also taken into account.
Typically, the profiles are divided according to playing strength, “Play &
Win” is a level that is intended for beginners and children, the other levels
then become increasingly stronger. Some profiles contain special features that
only the respective engine offers:
Special profiles you should try
In the following, we highlight a few profiles that access special features of
the engines.
Komodo Adaptive uses the in-game adaptation of Komodo. Here, the engine adapts
to your level during the game.
Shredder Neuronal uses internal NNUE function of Shredder. Here the engine
uses its neural network. Shredder Adaptive uses Shredder’s well-known good
adaptive mode. The engine adapts to its abilities after each game, depending
on whether you have won or lost. As a special feature, Shredder evaluates your
playing strength and gives you an ELO rating. These can be found in the info
box with the note “U1400” (= User 1400 ELO). After each game, by executing the
next “New Game” command, the result of the previous game is recorded and your
score is recalculated. Accordingly, the engine adapts to your skills. You can
use the feature to measure your training progress. Please remember to press
NEW GAME again after your last game to take over the rating, even if you want
to switch off the system so that your rating can be updated.
In the example, Shredder is currently set to 1223 ELO (C=rating of the
computer, if there is a U in front of it, it is the rating of the player
(user)).
Hiarcs Champion expects maximum strength, so you can, for example, carry out
analyses with the device.
Selection and control of profiles
If you press the COMF MENU button, you can select the engine in the top line.
The selected engine is displayed by means of a blue LED, the last used engine
is displayed in grey.
The lines 2 and 3 in this display then show the 6 available profiles. There
are 6 profiles available for each of the 3 engines.
LOAD PROF (Load Profile) opens the profile view, and CONFIRM loads it.
The Shredder Neuronal profile is preselected here.
In the 4th line you will find the control buttons with which you can load,
overwrite or restore the profiles, as well as the function for displaying the
current settings of the system. In the following we describe them in more
detail:
SHOW ACTV – Show current settings
“SHOW ACTIVE” shows you the current settings the system expects.
Under the ENG (ENGINE) button you will find all engine-related settings, such
as Threads, Hash, Ponder, Skill / Elo, NNEU and so on.
Under the GEN (GENERIC) button you will find all the general settings of the
system, such as level (time control), CPU speed, activated display options and
the selected options of the opening book.
If individual values are marked with a ” * ” at the end, this means that you
have last changed these settings in the system, and the new values can only be
adopted with the next new game. The background here is that some settings
cannot be adjusted during a game.
In the example, we have set an ELO limit of 1600 ELO based on the Shredder
adaptive profile. The SHOW ACTV menu now displays the affected UCI parameters
with *, because the settings have not yet been activated. To do this, we need
a “New Game” command. This is executed the fastest by lifting a piece in the
basic position and setting it down again. The “ping” tone for a new game will
sound and the new settings will be active.
Tip: If your pieces are in the initial position, simply lift up a piece and
set it down again. This will trigger the “New Game” command and the settings
will take effect immediately.
Tip 2: If you want such settings to take effect immediately during a game
without starting a new game, leave your pieces on the board. Then select the
NEW GAME command from the MODE menu, followed by POSITION.
In the position input menu, confirm the current position and continue with the
changed settings.
The typical settings that cannot be changed during a game are mainly the
change of ELO or SKILL levels as well as the use of the NNUE networks.
LOAD PROF – Loading a Profile
Use the LOAD PROFILE function to activate a profile previously selected by
means of the led buttons. By pressing the button you will first see the
preview of the profile, again with the distinction in ENG (engine parameters)
and GEN (generic parameters). You can now either load the profile with
CONFIRM, or use the PREV key to keep the previous settings.
SAVE PROF – Override a profile
You can use the SAVE PROFILE function to customize each of the pre-saved
profiles for the associated engine. To do this, load the profile you want to
customize. You can now change the desired settings using the CHSS SETT AND SYS
SETT functions. Go back to the COMF MENU and press the SAVE PROF button. The
system now shows you the preview of the (new) settings again. Use CONFIRM to
overwrite the profile with your settings. The name of the profile will now
change to “User 1”, which indicates that this profile has been changed by you.
For example, you can quickly and permanently adjust the Hiarcs Play & Win
profile from 1000 ELO to 800 ELO.
REST PROF – Restore factory profiles
The option RESTORE PROFILE appears if you have overwritten a profile. This
allows you to restore the factory settings of the selected profile. Other USER
profiles are retained. Select the USER profile to be restored and press REST
PROF. The system displays the preview as usual, confirm with CONFIRM and the
factory profile is restored.
The Hiarc CHAMPION profile has been changed by the user. The modified profile
can now be loaded, overwritten (SAVE PROF) or restored (REST PROF).
Hiarc’s CHAMPION profile is selected, it can now be loaded with LOAD PROF.
With SHOW ACTV, the system displays the currently loaded settings.
Operating instructions for the COMFORT MEN
The last selected profile is highlighted in dark grey, the currently selected
profile is displayed by means of the LEDs. Only after loading with CONFIRM
will the settings really be changed. You can thus navigate through the
profiles as you like and use the preview to see which settings are hidden in
the profiles. This will teach you how to use the different options of the
engines.
Within the selected engine, profile settings can be changed at any time by
simply making the desired adjustments via Chess Settings and overwriting the
existing profile with SAVE PROF.
TIP: The loading of a profile after a system restart does not take place
automatically. The system always loads the system parameters made by the user
via the menu as well as the most recently used engine with its default values.
For example, if you always want to play with Shredder Adaptive, press the COMF
MENU button after system startup. The last used profile is shown in grey
background, just press LOAD PROF / CONFIRM and Shredder Adaptive is fully
active again.
MODE – Mode Selection
TIP: You can only change the mode when it’s your turn! In case of a long
reflection time, you can force the move of the computer by means of MOVE.
Single player mode „HUMAN-COMPUTER“
The default mode to play against the selected computer engine.
Two-player mode „HUMAN-HUMAN“
When playing a human-against-human game, the computer pays attention to the
observance of the rules. Other functions, such as the ratings bar or the
information in the analysis box, are still active (according to the selected
display settings).
Analysis mode „HUMAN-ANALYSE“
For position analysis. You can enter moves for both sides in this mode. The
computer analyzes the position with the maximum performance of the engine
used.
Position input mode “POSITION”
The mode for entering positions. The position is changed based on the
current board position.
REVERSE: Changes the direction of play, LED OFF means white from below.
WHITE / BLACK: Use this to select the side that has the first move.
Castling rights: With the buttons Wo-o-o etc. you can set the castling
rights per color, W stands for white, B for black, o-o-o for castling long and
o-o for castling short.
TIP: Note that starting the position input mode will delete the history
of the current game.
New Game
Starts a new game from the initial position.
Alternatively, you can trigger the command for a new game by placing the
pieces in the initial position. If the pieces are already in the initial
position and you want to execute the command for a new game, then it is
sufficient to simply lift and set down any piece in the initial position.
TIP: If you have changed chess-specific settings such as game strength, you
must trigger a “New Game” command to make them active.
CHSS SETT – Chess Settings
With the CHESS SETTINGS you can make the chess specific settings. In this
menu you can configure your computer manually, i.e. without the help of
theprofiles.
TIP: You can use a profile that you like as a starting point for further
settings.
ENGINE – Selection of the current engine Allows you to choose between the
available engines in the device. Each program has its own strengths and
weaknesses. In addition, the Mephitic Phoenix is the first chess computer that
also provides neural engines, so-called NNUE engines.
Currently the commercial engines Komodo 14.1, Shredder 13.5 (with NNUE option)
and HI arcs 14.2 are available.
Stockist 15 (with NNUE option) is available as a free engine.
TIP: Changing an engine always automatically executes a NEW GAME command. If
you want to continue playing from the current deployment, please confirm this
via the position mode.
LEVEL – Selection of time
control
Use level to set time control, i.e. how long or how deep the chess computer is
allowed to “think”.
Example: “Seconds per move” Game Stages
Example: Tournament Stages
SEC / MOVE – Seconds per move
Press SEC/MOVE TO MOVE to the levels that specify a specific number of seconds
per move. If you press the SEC/MOVE button a second time, further selection
options appear:
Side 1: 1 second – 30 seconds / Side 2: 45 seconds – 900 seconds
Tap the desired time control to select it.
Tournament Stages
Here you will find the standard tournament stages with increments, for example
one game in 15 minutes with 10 seconds increment per turn.
TIP: Pay attention to the information in the status box that provides you with
explanations about the individual levels.
MIN / GAME – Minutes per Game
Here you will find the fast chess stages (minutes per game) without
increments.
PLY – Search Depth
With the PLY steps you limit the search depth of the computer so that it can
only “look ahead” to a certain number of moves. It will then play a weaker
game.
DISPLA SETTIN – Configuration of the analysis box
Use the DISPLAY SETTINGS to set what information the computer shows you in the
analysis box during the game.
MAIN – the main variant
Turns the display of the main variant on and off, i.e. how the computer thinks
the game should continue according to its calculations. The main variant is
very helpful if you want to play at a high level and see what the computer
thinks.
BOOK – The Opening Names
Toggles the display of the opening names on and off.
EXPERT – Calculation information for professionals Switches the expert
displays in the analysis box on and off, see also page 9.
HINT – The expected move
If HINT is disabled, a “—-” appears in the expected game development instead
of the expected countermove.
BOOK SETTIN – the settings of the opening books
Use BOOK SETTINGS to set which opening book you want to use and how widely.
BOOK SELECT
Select the opening book to be used by the chess computer or turn it off
completely. The device offers 5 different books:
The Millennium Book is written by Mark Uniacke of HIARCS and offers over
1,000,000 positions, all of which come from grandmaster games. It is the
largest opening book ever used in a chess computer.
The Fun Book offers rather unusual openings for experimentation.
There are 3 other books, “Carlsen”, “Fischer” and
“Kasparov”, which were generated from the games of the respective world
champions.
BOOK – Turn Using the book On or Off
BOOK turns the books on or off. When the book is switched off, the engine
calculates from the home position.
RANDOM – The random factor
RANDOM activates the random factor that varies the openings played.
DEPTH – Limit book depth
DEPTH limits the depth of the book, i.e. how many moves are played from the
opening books at the most, until the engine calculates its own moves.
THRESH – Limit to the best book moves
With THRESHOLD BOOK, you can determine that, for example, only the 25% best
openings are used. This limits variety, but produces stronger openings.
TIP: Opening training
You can use the device to train openings and try out the various opening
options. For example, if you do not like an opening played by the device, use
the BACK function to reverse the move. Now press MOVE, the computer will
automatically play the second best move from the opening book, and so on. With
this function, you can “scroll through” the opening variants directly on the
board.
ENGINE SETTIN – The engine settings
The chess computer uses the UCI protocol and can operate various engines. Each
engine has its own specific settings. The most important settings, however,
are offered by almost all programs, so that you can find them centrally under
the menu item ENGINE SETTINGS.
The submenu ENGINE DYNAMIC also offers the functions that the selected engine
offers. These differ depending on the selected engine.
ELO – Limitation of the engine’s playing strength With ELO, the ELO playing
power of the respective engine is limited. You can easily adjust the playing
strength to your own ability.
Here are some special features:
ELO OFF means that the engine expects maximum strength.
Shredder: In the case of Shredder, OFF means that the neural network is
connected too. Adapt switches on the adaptive game strength including the user
elo rating (analogous to the profile Shredder Adaptive).
Komodo: Komodo does not offer ELO levels, so the menu item is not active when
Komodo is selected as engine.
Please use the Skill Levels in the ENGINE DYNAMIC menu to set the strength of
Komodo.
HASH – Resize the hash memory
Specifies the size of the hash memory used by the engine. Especially in
endgames with few pieces, an increase in hash memory (deviating from the
standard specification) can lead to better performance, especially in the case
of long computing times.
THREAD – Number of simultaneous calculation processes
With the THREAD setting, you enable 1 or 2 computing processes for the engine.
The more computing processes are available to the engine, the more powerful it
normally becomes. Note that the power consumption and temperature of the
device may also increase. Comment: Hiarcs 14.2 can only work with 1 thread.
PONDER
“PONDER” means that the engine calculates even when it is your turn. It
therefore uses more reflection time and will play a correspondingly stronger
role.
SPEED
Sets the speed limit of the processor. The lower the set value, the weaker the
corresponding chess program plays.
ENGINE DYNAMI
Under ENGINE DYNAMIC you will find all the UCI settings that were not
mentioned before, but which have an influence on the gameplay of the engine.
The available settings vary from engine to engine. Typical examples are the
king safety, playing style, in the case of Komodo and Stockist skill levels
and also Auto Skill (Adaptive
adaptation at Komodo). In Stockist, for example, there is the function “USE
NNUE”, which switches on the neural network. The most exciting functions of
the commercial engines have already been stored in the profiles for trial and
error.
In the example we see the Engine Dynamic menu of the Komodo Engine. Here, for
example, king safety (how much importance the engine places on the protection
of its own king) or the player personality (aggressive or passive play) can be
changed. The options offered vary from engine to engine.
SYS SETT – System Settings
Important: These settings apply throughout the system!
Here you can set the system-wide settings, which also apply to the other modes
that can be selected in the main menu.
SOUND – Sounds
Toggles the sound on and off
VOLUME – Sound volume
Here you can determine the volume of the sound effects.
BOARD – Cable right or left?
Determine whether the cable on the board goes off to the right or left. On the
right is the normal state (the logo badge points to you), on the left the
board is rotated so that you can continue to play with the white pieces from
below.
BOARD LED – brightness of the board LEDs
Determine how bright the LEDs should light up in the board.
SELECT VERSION – activate latest version
SELECT VERSION allows you to go back to previous firmware versions if you
wish. After receiving updates, you can activate the latest firmware version
with this function.
Confirm with CONFIRM if you want to change a firmware version. The system now
displays the latest available version. Confirm this with CONFIRM or select a
different version with LEFT / RIGHT.
TIP: Note that changing a firmware version is always associated with
rebooting the system.
UPDATE – Perform system update
With this function, the system searches for updates, both on the USB port and
via WiFi on the update server.
Make sure that your device is connected to WiFi if you want to install updates
from the server.
If you have purchased additional software for your chess computer in the
webshop at www.computerchess.com , it will
also be transferred to your device via the update function and installed.
After a successful download of an update, it will be installed automatically.
Look for the ads in the status box to track progress.
If all updates have been installed, you can retrieve the latest version with
the function SELECT VERSION.
LANGUA – Set the language of the system
Use the LANGUAGE menu item to set the system language. The texts in the
buttons do not change, but all system messages in the status box are output in
their selected language. English, German, Dutch, French and Spanish are
available.
RESET SYSTEM – Perform system reset
This function resets the system to factory settings. Attention, this deletes
all user-related data such as: Your WiFi settings, but also custom profiles or
the ELO values of Shredder.
WIFI – Connect to a wireless network
You need a stable WiFi connection to perform updates and to play online games
on Lichess.org (not yet implemented in version 3.55E). With the WIFI button
you can establish the connection.
As soon as you access the menu, the device automatically scans the available
networks. Also pay attention to the status indicators in the status box at the
top of the display.
The device has 2 WiFi adapters and supports both 2.4 and 5 GHz networks.
After scanning, it will show you the found networks with their names, for
example: ‘M2000 / wlan0 / 54 / 64’.
M2000 is the name of the network, wlan0 denotes the WiFi adapter, 54 is the
signal strength and 64 is the channel of the network. If you see your network
twice (once with wlan0 and once with wlan1), please select the one that
indicates the highest signal strength. The signal strength should generally be
at least 50, otherwise the network is too weak. If you do not reach this
value, you must place the chess computer closer to your network router.
Choose your network and enter the password. The password is stored in the
device until you call up the WiFi menu item again or reset the system.
The status box gives you information about whether the connection was
successful.
Once the device is registered in the network, you can simply switch WiFi on
and off using the WIFI button on the top right of the control screen.
PGN USB – Export your games as a PGN file
This function allows you to export the last game to a USB flash drive. Plug
the drive into the USB port and press the PGN USB button in the system
settings. All your games will be updated on the drive in a file in PGN format.
You can then open it with a chess program or interface.
Note: The USB flash drive must be formatted with the widely used FAT32
standard.
INFO SYSTEM – View the latest information about the system
Here you can view current system parameters, such as firmware status, serial
number, processor temperature, WiFi connection status, device Mac address, IP
address
(if connected), signal strength, and board connected information. This
information may be of interest to our service team if you contact us with any
issues.
Features that can be activated directly on the board
Some features of the chess computer can be activated directly on the board:
New Game
Place the pieces in the initial position. The last piece set up automatically
triggers the “New Game” command. If the pieces are already in the initial
position, lift up any piece and set it down again.
Move back mode
Start the move back mode by simply moving back the last move of the computer.
The BACK button in the control screen lights up, the board now shows you all
the moves played one after the other. Move back as many moves as you want and
exit the Move back mode by pressing the BACK button when finished.
PLAY RETRO CHESS“ MODE
In the “PLAY RETRO CHESS” mode you will find emulations of old chess computers
against which you can play at different speeds. This mode is optional in the
Mephisto Phoenix, if you have not yet activated the emulation package for your
device, you can do so at any time via the webshop on
www.computerchess.com.

Starting an emulation
Select an emulation by touching the corresponding abbreviation of the
emulation in the overview, e.g. AM for the Mephisto Amsterdam.
With the Tasc King as well as the Mephisto Almeria – London emulations, you
can select the next configuration level of the available memory of the
emulation by exiting and restarting an emulation. With the Mephisto Nigel
Short, you select the Milano emulations in this way.
Controls in the emulations
Structure of the emulation screen
The screen of each emulation is structured as follows:
The upper part (above the white line) shows the original display layout of the
chess computer of that time. In this display area, there is a “hidden”
function that allows you to switch between the original speeds of the
processors at that time and fine-tune the speed in 1% steps.
Directly below you will find the “Speed-Bar”, i.e. the knob for setting the
speed of the emulation.
Below the program name, you will find the original keys of the emulated chess
computer in 3 destinations, in the above example as PLY, BCK, MEN and so on.
The last line is reserved for the system functions of the emulations.
Set emulation speed
By default, the maximum possible speed of the respective emulations is set
after program start.
You can now change this to the original speeds as follows:
1 x tapping of the display area in the middle:
The speed of the original chess computer in the basic version is set. Each
further tap on the display in the middle sets the speeds that simulate faster
program versions of “back then”. For example, 10 MHz of the standard devices,
18MHz of the then turbo kits for 6502 processors or 33 MHz or 66 MHz for
tournament machines of the
Motorola 68xxxx processors.
The set situation can be read in grey to the left of the scale.
Regardless of this, the speed can be set in +1%/-1% steps based on the full
scale length by tapping the display in the right (for +) or left corner (for
-).
Original button layout of the chess computer
Example: Mephitic III-S (Glasgow) (see illustration)
The offered buttons of the chess computers vary from emulation to emulation
and follow the original devices of that time.
Control keys of the emulations
MEN – Back to main menu
This key is placed in the bottom left corner of each emulation and returns to
the main menu (PLAY AGAINST COMPUTER / PLAY RETRO CHESS)
SND – Sound
Sound output ON/OFF
SEL – back to the selection screen of the emulations
The button takes you back to the selection screen where you can select a
different emulation.
RES – (Reset)
This directly triggers a NEW GAME for many programs. Exception: The Mephisto-
emulations in the bottom row.
Here you get to a selection menu (CONT START DELETE…). Navigate with the arrow
keys to START, then Enter, and start a new game.
Please note that a RESET of the emulation (RES key) takes longer at minimum
CPU power than at original speed.
SAV – (save)
Available for the emulations of the first and last line of the selection menu,
saves a started game. You can then CONTINUE using the RES button with the
option CONT.
Instructions for emulations
For legal reasons, we are not allowed to provide operating instructions for
the original chess computers, since the copyrights lie with the respective
author of the instructions (and not with the author of the actual chess
program). In most cases, however, you can easily find them online or find help
with like-minded people in the forums on the subject of chess computers.
Back to Main Menu
Press the MEN button in the emulations to return to the selection screen.
PERFORM RESET
If your system stops booting because, for example, a problem occurred during a
system update, you can use the RESET button on the back to start in a safe
mode.
To do this, press the reset button as soon as the control led on the back
lights up.
From Safe Mode, you can select and launch the latest version that ran smoothly
on your system. From there, you can, for example, perform a system update
again.
