This page mainly aims to list some hardware related to Arcade Mahjong.
Some examples of Mahjong Panels are below
Astro City (Sanwa) | Astro City (Seimitsu) |

Adapters are often simply a Jamma fingerboard wired to a Mahjong edge connector, as described in the pinouts on the main page. You should be able to find some on Yahoo auctions, which will need a proxy service to buy from.
Some useful links are below:
MVS does not use the typical connection matrix of Mahjong panels. Instead a custom one is used, so an adapter or custom panel will be needed.
To enable use of a Mahjong controller/panel, set Hardware DIP #3 to enabled. The connection matrix is then:
OUT1 (pin 10) | OUT2 (pin 2) | OUT3 (pin 9) | |
---|---|---|---|
UP | A | H | PON |
DOWN | B | I | CHI |
LEFT | C | J | KAN |
RIGHT | D | K | RON |
A | E | L | REACH |
B | F | M | |
C | G | N |

Uses Jamma pins on parts side as KEY, and Sega I/O CN3 as COM.
Set the Jumper "JP1" on the JVS I/O to 'B' (high).
JAMMA #17 | JAMMA #18 | JAMMA #19 | JAMMA #20 | JAMMA #21 | JAMMA #22 | |
---|---|---|---|---|---|---|
I/O CN3 #4 | A | E | I | M | KAN | START |
I/O CN3 #5 | B | F | J | N | REACH | BET |
I/O CN3 #6 | C | G | K | CHI | RON | |
I/O CN3 #7 | D | H | L | PON | ||
I/O CN3 #8 | LAST | TAKE | WUP | F.F. | BIG | SMALL |

Uses an adapter board which plugs into the bottom of the motherboard, and another adapter board which plugs into the edge connector. This produces standard Mahjong pinout.
Uses an adapter board which plugs into the motherboard, and the edge connector..
Uses an adapter which plugs into the Jamma edge connector, and the back of game cartridges.
The pinout is slightly different than regular Mahjong pinout. There's a video GND on pin 10, and the key matrix is quite different. For Aleck 64, the controller matrix is:
PIN #1 | PIN #A | PIN #B | PIN #2 | |
---|---|---|---|---|
PIN #T | - | START | - | - |
PIN #M | B | A | C | D |
PIN #N | F | E | G | H |
PIN #P | J | I | K | L |
PIN #R | N | M | CHI | PON |
PIN #S | REACH | KAN | RON | - |
The adapter also has an ethernet connector that allows linking two motherboards.

Uses 3P and 4P connectors on the motherboard.
3P (1) | 3P (2) | 4P (1) | 4P (2) | |
---|---|---|---|---|
4P(5) | A | B | C | D |
4P(6) | E | F | G | H |
4P(7) | I | J | K | L |

4P(9) | KAN | REACH | RON | - |
4P(10) | START | - | - | - |

Uses CN2 as COM ports, and Jamma pins as KEY.
CN (2) | CN (3) | CN (4) | CN (5) | |
---|---|---|---|---|
1P UP | A | B | C | D |
1P DOWN | E | F | G | H |
1P LEFT | I | J | K | L |
1P RIGHT | M | N | CHI | PON |
1P BTN 1 | REACH | KAN | RON | - |
1P BTN 2 | START | - | - | - |
TODO: Figure out of REACH an KAN being in this order is a typo. Feels like they should be swapped?
