Various thoughts I had during the
- First I wanted to (re-)build a basic cabinet, just for MAME,
i.e. a PC with monitor in a special case. I looked around
on various websites, and decided that this would break up
my cabinet, and would cost me too much money, just for a MAME-machine.
- Suddenly I stumbled upon some arcade-cabinets in the Netherlands.
I bought a generic cabinet, with a SF-II board, 2 speakers
on top and in a good state. The monitor has very little burn-in,
so I decided to do something like the PC2Jamma-project.
I liked the idea of adjusting the PC for the cabinet instead
of otherwise. Besides that, a real arcade-monitor is just
much nicer than a pc-monitor.
- I have access to some original Jamma-PCB's, and wanted
to be able to play them, as well as MAME. This means I will
have to do some rewiring, but in a way that still allows a
Jamma-board in the cabinet. This will also take some extra
electronics, but if you do something, you've got to do it
BTW: if anybody has a (cheap) Bubble Bobble or Pang pcb for
sale here in Europe, you can always contact
Some things I'm encountering during the process:
- Buttons & Joystick-grounds
- Using the keyboard-encoder, I have two grounds. A Jamma-connector
has only 1 ground (on various pins). This means I'll have
to seperate some grounds on a fingerboard, and rewire the
buttons. This will only work if the grounds on a pcb are
internaly connected (as is supposed to be).
- Single pole, double throw
- I will have to add some switched for setting the cabinet
up for MAME or Jamma-pcb use. This is mostly because the
encoder-ground question (see above). It also has to do with
the 3 extra buttons/player (not part of the Jamma-specs).
They are now grounded to the extra connector on the pcb,
but in MAME-use, they will have to be grounded to the normal
ground, used by all other buttons.
The cabinet works nice and smooth with the rebuilded control-panel.
It is much easier to win SFII now!
