Connect a PC to a JAMMA cabinet in seconds!
New Version!
The J-PAC (JAMMA interface for Pc to Arcade Controls) is a board
which allows plug-in connection of a JAMMA arcade cabinet to a VGA
card and keyboard port or USB port on a PC motherboard. It incorporates
all the advanced features of the I-PAC with an on-board JAMMA connector
NEW VERSION! Now has inputs fully protected against static discharge
and reverse connection, now supports 3 extra JAMMA connections (Tilt,
Service SW and Test)
Now supports 12 volt coin doors.
Fully programmable key code set. Stored even after power off.
Dual interface USB or Keyboard.
Supports I-PAC optional pre-assembled LED harness with 3 panel mounting
LEDs which emulate the keyboard Lights.
Lead plugs into keyboard socket on PC or USB port.
Self-Test LED gives an instant check of all your wiring. Can indicate
which, if any, input has a problem.
No separate power needed.
Does not use a matrix - no ghost keys. All inputs are completely
separate and generate their own interrupt - this is the fastest possible
method.
Does not use a scanning method which causes a variable delay.
Either uses standard MAME keys or you can program your own character
set.
Shift functions. Holding "Start1" and pressing other buttons sends
a range of codes for MAME functions such as "escape", "Coin 1", "tab",
"enter". This means no extra buttons are needed on the cabinet. In
programmable mode any input can be the shift key and all keys can
be programmed with a shifted code.
Connector for ordinary keyboard which can be used together with the
controls if required.
No special drivers needed. USB drivers are generic Windows.
All control inputs which are part of a normal JAMMA standard are
routed to an on-board JAMMA edge connector.
Connector for VGA input from PC VGA card. Routes through to JAMMA
edge connector for connection to the cabinet arcade monitor.
On-board video amplifier boosts signal to standard arcade monitor
levels. Uses high-bandwidth video amplifier chip.
Custom microcontroller only allows sync signals to be sent to the
monitor if they are in the correct range that the monitor is designed
for. Avoids driving the monitor with a too-high horizontal sync rate
which can damage some arcade monitors.
Sync circuitry also converts separate horizontal and vertical syncs
into composite sync. Can handle both positive and negative vertical
sync.
If required, can divide a 31Khz VGA signal in half so that it will
display a stable picture on a 15Khz arcade monitor. Useful for checking
boot-up progress and configuration (not for application use). Automatically
stops dividing the signal when it detects a correct 15Khz rate is
being send by the PC.
JAMMA cabinet speaker routed to screw connectors for wiring to powered
sound card or hacked PC speakers.
Legal Note.
For legal reasons we must state here that the J-PAC is not designed
to be used in revenue-earning applications where a credit mechanism
is used. The J-PAC contains no specific interface functionality for
any credit device. Although it has inputs which connect to the JAMMA
coin signals, these are designed such that activating a switch connected
to them causes the MAME "coin" keycodes (5 or 6) to be sent. These
are designed to be used with panel pushbuttons not coin doors or
note acceptors.
