  • 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.
  • Supports I-PAC optional pre-assembled LED harness with 3 panel mounting LEDs which emulate the keyboard Lights.
  • Lead plugs into 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.
  • 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 JPAC is not designed to be used in revenue-earning applications where a credit mechanism is used. The JPAC 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.

    Fabulous. Flawless. Just what I needed

    Posted by David on 16th Apr 2019

    I wanted to connect a raspberry pi loaded with retropie into my turtles cabinet and was struggling to find a decent way.
    I bought this J Pac along with a hdmi to vga adapter off ebay and i also use the i pac 4 for the 4 player controls.

    the jpac works right from the pi's usb port as does the ipac 4.
    i needed to simply change the resolution in the pi's config.txt and this outputted a perfect picture!
    it shows a sync light when all is working well so you know that you need to adjust your monitors settings to get the picture to hold correctly.

    very please with how well this works with the raspberry pi using a cheap hdmi to vga adapter you dont need anything else!

    Great product for connecting PC to JAMMA

    Posted by Simon Tettmar on 1st Jan 2017

    Great card, simple to connect and works with no config at all letting me connect my computer to the jamma harness and hence all my cabinets controls. The app you can download does a nice job of customisation.
