This is one of those times where folks worry about giving advice because it doesn't look like you know what you are really doing, then they give advice and then magic smoke is released everywhere.

If it *was* obvious to you , the you should have made it obvious in your diagram. I would say that the majority of new folks seem to think that the AC power for the monitor comes from the switching PS.

The definitive wiring page is still Bob's:

Before giving specific advice, I would prefer to see a clear picture of how things are wired around the ISO, although I think Ed is right.



Perhaps the most important question has yet to be asked ... how are you planning to interface the controls and monitor to your PC ?

DashRendar:
My apologies if I wasn't specific.  There's no "magic smoke" intended, heh.

To be clear- I assumed the AC power fed into the PSU (as it does in a PC), rather than anything else (the isolation transformer).  I'm not currently home, but have a couple photos I took of the inside to go off of.  Thanks to the advice, I see that's not the case.

This is my first cab, but I have a very strong technical background and do pretty good with electronics.  I'm also cautious.  This is why I came here looking for answers on the forums and wiki rather than attempting to unplug things and make mistakes.

Regarding the controls- I have 2 U360s which will connect up to the USB ports on the PC.  I have the I/O harnesses that Andy makes to connect the buttons directly to the joysticks.

Regarding the monitor hookup- I have an ArcadeVGA 2 that I'm going to be using.  Picked up the VGA adapter to connect to the end of the video cable to interface with the Arcade VGA.

FWIW, that was a harsher reply than I intended and caution is advised in order to protect the stuff that you have spent money on (be it in the old cab or shiny new stuff). I expect that Ed is correct with his assessment, although before you go cutting anything, I always like keeping my converted cabs as JAMMA to provide for nice, easy interfacing of the video circuitry.

Cheffo: No worries, I understand.  It actually concerns me sometimes that brand new folks get into this hobby, messing with potentially lethal currents without realizing the danger.

Ed: It's a JAMMA cab, but I'm not using a JPAC.  Instead I'm using Ultimarc 360s.  The cab has 49-way sticks which I'd rather not mess with.

I have been tempted to leave the PCB etc still intact though, for the odd times I'd like to play Blitz '99.  I won't be able to afford a rig that can emulate that in a playable state for a while, and I KNOW my brother and father-in-law love that game!

It'll be a PITA to switch it back, but not impossible.   :angel:

By the way, thanks everyone for the advice.  I do appreciate it.

Magic smoke is what comes out of burnt up equipment when power is wrongly wired.

Again, you have to think deeper: Even with a PC, where does the PC's monitor get power from? Not from the PC's power supply. But I think you get it by now...


--- Quote from: Ed_McCarron on October 26, 2009, 05:38:18 pm ---Yeah, bear in mind I only addressed turning off the power supply like you asked in the first post.  If it is a jamma cab, then you might want to leave the PS connected to power up a JPAC or the like.

More misinformation. The JPAC does not use power from the power supply. It's powered off the PC's keyboard port.
