Update on power supply problems with Virtua Fighter 3 (Model 3) PCB
Finally have an update on the power supply problems I’ve been having with my Virtua Fighter 2 and Virtua Fighter 3 respective Model 2A and Model 3 boards.
After tracking down an eBay sale of a Model 3-fitted and ready PSU, I buckled, bought it, and it finally arrived yesterday. I gave it a preliminary run to see if I could get the thing to power up, and it looks like we may just be in business 🙂
The setup’s nothing too refined, but is startlingly effective – it’s basically a standard ATX power supply running on 240v with the 12v, +5v, +3.3v and GND going to a couple of distributors on a block of wood, and the distributors rope around to the various connectors on the board. The input and video run back to a JAMMA biscuit, and the sound (not connected) has been wired to a 4-pin molex connector, but currently doesn’t have an amp fitted.
Moving forward, from here I’ll need to take the Wei Ya audio amp off the existing Model 3 >> JAMMA adapter I have and fit that into the loop and connect it up to the JAMMA biscuit to get sound going through. Will have to look at doing something similar for my Model 2 board as well, might see if there’s a way I can quickly hook up the PSU to my Model 2A filterboard to at least test the thing and see if I can get the sucker powering up.
The funny thing with all this is that Wifey said ages ago that I should have gone out and grabbed a big beefy power supply for the system before messing around with everything else I’ve done. Looks like she was right all along 🙂
Once I’ve had a chance to properly connect the whole shebang together and get it up and running, I’ll post up some pics to share. Might also prove useful to other people interested in doing similar mods on their systems.
