After my first multi jamma conversion with my doudble dragon cab last year, i have decided to go back to work :work: with a new Multi-jamma project...
here is the link of the previous project:
http://www.arcadefever.net/MYPROJECT/MULTIJAMMA/MULTIJAMMA.htmlThe point of doing that, is to empty my PCB shelf, and play the games, without swapping them all the time ...
On that Project, i choose my Tetris cab. One of the main reason, is the cab as a lot of space inside, wont be a problem to host 8 to 9 PCB, and it is already wire Jamma
For the games, this is my selection:
tetris
vigilante
bubble bobble
great 1000 miles II
shadow dancer
ghools and ghost
wonderboy
bionic commando
V-ball
it is going to be a total of 9 PCB inside, one will be off and 8 powered at the same time
Here is the cab:
first thing to do, remove everything ...
I decided to change the monitor, and to add a brand new one. The old one is not to bad, i am going to keep it, and do a capkit job on it...
here the new monitor:
the old one, very dirty
Done, the cab is empty, only left over, the power supply...
Ok, know it is time to get smart
i learn my lesson with my first project, and this time i have plan everything much better.
i am not going to attach the PCB to the sides of the cab. I have build a Rack, like that it will be more easy to rewire everything together, and easy to remove any PCB...
I am not a good carpenter, but i have manage to do something decent...
no nails, only hot glue
to suport the Rack, i add 2 little pieces of wood, on each sides of the cab. I also added a power strip, that i rewire to the main power source of the cab. It will help me to power the monitor and the 2 extra power supply...
ok, the rack is secure, ready to host the PCB...
on each side, under the rack, i will add the 2 extra power supply ...
This where i got smart
i bought bunch of pc power connections...
+5 +12 gnd
here are the 2 new power supply...each of them will power 4 PCB...
the main power supply of the cab, will only power the multy jamma mother board...
i did also a much more clean job on the wirering
Here we go, time to install the beast
the green wires, will be connected to the button, for switching between games...
time to put it in
all PCB are place into the rack ...
each PCB is rewire to the multi jamma by a pc cable connection, and a mini pcb
The main problem of having 8 PCB on at the same time, is the HEAT ...
that why i got some little fans... A total of 4
2 of them on top of the cab, just behind the monitor, to push the hot air out ...
2 of them on the bottom of the coin door, to push the air IN ...
know it is time to put everything back together
TIME TO PLAY !!!!!!!!!!!!!!!!
ps: some of the games, are not jamma, that why i build some jamma loom to make them work with the multi jamma...
also few games, needed and extra wire for the -12v
first game and the one that most people are going to ask me about
SHADOW DANCER !!!
how can you play it in a cab with only 2 buttons :|
well the game use the 3rd button for the power of the ninja, so it is not use very often..
what i did, i rewire the 3rd button of the jamma to the right side of the 2nd joystick
that mean that everytime i need to use it, i just have to move my right hand a few inches to the right to move the 2nd joystick to the right
it is very easy, and simple. it does not affect the game play at all !!!!
i really LOVE THAT GAME
BIONIC COMMANDO, a very cool game...
V-BALL a cool and fun volley ball game, a must to play with a friend
VIGILANTE
GREAT 1000 MILES RALLY II very fun, even with a joystick
BUBBLE BOBBLE
WONDER BOY
GHOOLS AND GHOST the best for last
Ooops
I forgot to take a picture of the main game ...TETRIS
well, so far everything work perfectly...
that a total of 17 games in 2 cabs shock: "tetris and double dragon"
the 48 games in galaga, the 1942 and 1943 reunion in one cab
and the 3 in 1 commando cab
a lot of GAMES
