The smallest JAMMA cabinet that is - what did you think?
Well, this thread will be my contribute to this great forum and a showroom for my latest project.
The intention, or maybe challenge, was to see how small a full functional JAMMA cabinet with a CRT monitor could be.
As you can see I have been inspired by other builds here at the forum. Bella's Arcade is of course one of them, that has to be mentionend.
It is not fully built yet, but is starts to shape up in something that I'm satisfied with.
Some facts. The CRT tube is actually an old 14" TV, that I looted and build a SCART adapter with resistors.
Obvious upside is that all colors and settings are perfect from start. The downside is that I have less control of HOR and VERT size and position.
I started the build with a real arcade tube, but the China chassi PCB gave me such a headache, so I threw it away.The PCB powering this beauty is an ICADE 60-in-1 multi PCB, that has the most (vertical) classics in it.
Why not a MAME build, some might ask. Well, already been there and I wanted to do the real thing this time.
Maybe there will be another thread with the MAME project later on...The speakers are two 5$ car speakers, and that's perfectly fine. Anything more expensive would be a waste, since the audio on these multi PCB's are so damn distorted.
The marquee is lit by a CCFL tube, which is nice both regarding voltage and no interference transmitted from it.
I bought a pre made JAMMA loom to save some time, and both joystick, buttons and PSU are from
www.arcadegames.se.
T-mold is from
www.t-molding.com, and I'm about to put in an E-limitator (great gadget by the way) from
www.arcadeshop.de to have movement restrictions i 4-way games like Donkey Kong and Pacman.
The sideart are made by my self, with origins from original bezel and sidearts. It is printed in a local print studio with a lot of help from a friend there.
I have some bugs to sort out though. I still haven't hooked up the coin acceptor yet, and I also need to install TEST and SERVICE buttons.
The ICADE 60-in-1 PCB also generates a lot of interference to the sound when placed within the cabinet. I have found out that it is the CRT tube that is the bad guy, so I'm trying different positions and shields to prevent this. It is playable though, but very annoying.
But when building as small as this, there has to be a compromise or two somewhere I guess.
