E-Limitator Build, Review & Test (In Progress)
John Bud has been forwarded the new E-Limitator interface to build and review (from Luigi). However, to avoid confusion, John has asked me to do this on his behalf to which I have happily agreed.
PLEASE NOTE: Anyone is welcome to post here, I will be edited this post with any progress.
The actual build, install and test will be carried out in the course of the next couple of weeks. I will add more as I progress.
The package came with the following components;
1 x E-Limitator PCB (Decent construction and labeled)
1 x 28 pin ATMEL ATMEGA8-16PU Microcontroller pre-flashed
1 x 28 IC Socket for ATMEL ATMEGA8-16PU Microcontroller
1 x 4 pin RGB LED
1 x Electrolytic Capacitor (25v 47uf)
2 x Wire Terminals (For joystick in/out)
2 x 100 Ohm Resistor
1 x 150 Ohm Resistor
1 x Capacitor (100nF)
PCB (Component size)
PCB (Solder side)
Atmel Microcontroller & Socket
Other things not included in the kit but required is a switch/button to cycle through the four different Joystick modes the E-Limitator has to offer, these are;
8-Way (Purple LED)
4-Way (Blue LED)
2-Way Vertical (Turquoise LED)
2-Way Horizontal (Green LED)
Immediately, I noticed that the E-Limitator interface requires a +5V feed to power it, this would of course come from the PSU used to power any Arcade PCBs.
The interface will be installed into an Electrocoin Spectrum JAMMA cabinet.
Ideally, for me, I would want to install this interface without having to hack any JAMMA joystick interface to accomodate it. After giving it some thought, I decided the best way to implement the installation of the interface was to have it literally plug into the 9 pin Mate-N-Lok Joystick harness of a JAMMA cab. It would make for a neat install and would allow easy removal of the interface.
This interface, if it works as well as it is claimed would solve a problem for which I have been trying to solve easily. It would allow me to play Pac-Man without having to swap out my Electrocoin Joysticks of which I am fond of. It also means I can switch from 8-Way to 4-Way at the press of a button, which is handy for a 60-In-1 PCB or MAME install.
I will need to order a 9 pin Mate-N-Lok plug and socket from Swallow Amusements to complete the build, other things to consider are where the Joystick Mode button will be sited and where to place the RGB LED where it can be seen (essential to determine what mode interface is currently in).
The install manual for the E-Limitator is available here;
I should also add that you should be fairly good with a soldering iron to complete this build and able to follow fairly basic instructions. I would say that some basic electronics knowledge would go a long way for the build.
