<p>Gomados: </p> <hr /> <div>[[Category:PCB Tech]]<br /> == Small add-on circuit to add -5V to your PSU/Jamma harness ==<br /> [http://dimensionengineering.com/Negatron.htm] Negatron from Dimension Engineering&lt;br&gt;<br /> ATTENTION - The Negatron device provides -5v@500mA, which may be insufficient for some pcbs.<br /> <br /> == Cabinet Power Suplies with known issues ==<br /> Sega Astro City 400-5198-01 PSU's suffer from having an under-powered -5v regulator<br /> rated at only 500ma fitted by design. This is not powerful enough for a lot of games <br /> that require -5v, most notably Bubble Bobble and Taito G-Net motherboards. A kit is <br /> available for this PSU that upgrades the weakness available here:[http://www.andysarcade.net/store/index.php?act=viewProd&amp;productId=1541]. <br /> Other models of Astro City cabinets/PSU's may be affected but have not been verified as yet.<br /> <br /> == JAMMA PCB's that require -5 volts ==<br /> <br /> Cadash - No sound<br /> <br /> Double Dragon - Required for music<br /> <br /> Donkey Kong<br /> <br /> Fighting Hawk - No sound<br /> <br /> Gals Panic 2 - No sound<br /> <br /> Mortal Kombat 2<br /> <br /> NBA JAM - No sound<br /> <br /> NBA Maximum Hangtime - No sound<br /> <br /> Pit Fighter - No sound<br /> <br /> Rainbow Islands - No sound<br /> <br /> Rampage World Tour<br /> <br /> Thunder Fox - No sound<br /> <br /> Toki - Required for sound amplifier<br /> <br /> Most if not all Midway pcb released in the 90's<br /> <br /> Combat Tribes - No sound<br /> <br /> Super Dodgeball (tecmo PCB, not neogeo) - No sound<br /> <br /> Bubble Bobble - required for board functionality<br /> <br /> Rastan - No sound<br /> <br /> Liquid Kids- No sound<br /> <br /> Volfied - No Sound</div>
