Questions about a Gauntlet Legends that needs some TLC

So I picked up a Gauntlet Legends (probably not real popular here), no monitor, but with all the boards and parts. I'm looking through the manual and the game, and it looks like it's a bit of a hack job on the inside. The main boards/video card are correct, but it has this odd power supply combination instead of the one unit shown in the manual.

Also, the boards aren't mounted in the metal grounded case it should be, so I'm thinking thats an issue. What do I need to do with this? What should I do to ground the boards. I'm thinking of getting a correct PS instead of using whatever the hell is hacked up here.

Someone went to a lot of effort to hack in that supply! It looks like the whole power assembly from a driving game. Is there an isolation transformer in the bottom part of the hacked in supply? Is it a dedicated game or was it converted? Can you tell what monitor is in the game? I would verify that a monitor that needs an isolation transformer hasn't been installed as they could have just hacked in the small supply on the top of that power assembly with a lot less effort. The original supplies are available from Happ for around $70 or so.
 
Are you sure the PSU's aren't correct?

Can't remember exactly what they are off the top of my head, but my MK4 & NBA Showtime (which are same era Midway cabs - think the Showtime is very similar to Gauntlet Legends) have the same 2 PSU layout.
 
The game had no monitor with it. I'm currently looking for one. The game is dedicated, and that PS isn't correct. I don't know how well it will work nor how to hook up things to it with it's current wiring scheme. I've got a screenshot of the manual posted down below.

What about the boards not mounted to a ground plane? Should I mount a rectangle piece of aluminum/thin metal to the shelf, and then mount all the electronic parts to that since it's missing the electronics box?

Edit: I just decided to buy a new original PS. I would have just gotten a basic 200w and wired it myself, but I didn't want to mess with rewiring connectors. So, the power supply issue should be fairly resolved. Who wants the one in it now? ;)

That videocard isn't standard faire Vegas -- is that a Voodoo5? They're supposed to have a Banshee, which is a single BGA IC, not that hot mess...

Lay that hard drive flat! And mount it to something on top of rubber standoffs. If you shipped/moved it like that, I'd be genuinely surprised if it still worked...

The second power supply was definitely hacked in by someone -- no factory uses frickin' wire nuts. That said, it looks like a normal PC-AT unit -- so it should have all the right voltages, ergo as long as it's hooked up right it should be fine. The label should tell you which wire colors carry what voltages; compare this against your schematic to make sure everything's getting the +V/-V it wants, then fire it up!

I'm not too worried about the grounding. The metal case is more to protect the boards from something conductive falling on them, perhaps in the event of a violent monitor failure. If you just want to make sure everything works, you can power it up as-is.

The video card came out of a Gauntlet Dark Legacy. I was told it would work just fine, and I guess we'll see.

Hard drive wise, I've seen computers with vertical mount drives, Xbox 360s stand up with hard drives running vertical, so I don't know that there will be an issue there. I can get a new drive for it for ~$25 anyway if needed.

I think I will still look for a piece of aluminum to mount everything to. I assume it would be better to tie everything in than not.

Actually, if a 360 is standing on end, its HDD is laying flat... you might be thinking of the optical drive.

Spurious hard drive failures happen all the time, and many games are locked to their HDD so you can't simply replace it. Therefore, you should take extra care to try to keep your good drive going.
 
The original supply is by far the easiest route. It is a strange arrangement, there is an AC receptacle on the top of it that powers the Marquee lights and the back door is cut out where the supply goes. When you get the supply in you want to test the new supply and let it run a while. I've bought three over the past couple of years and two of them died within a couple of weeks after I got them.


I'd try to find an original mounting plate. There are a bunch of standoffs on it and its probably going to be a chore to get them all lined up.

Well, that doesn't sound encouraging. I bought it off Ebay, supposedly brand new. I'm not in the mood to have one go out after a few days.
 
Another item you may want to include is a second cooling fan for the video board. I noticed yours only has one fan and your video board does not have the heatsink fins. The second fan will help your video board last longer. I also agree with mounting your hard drive. These drives are very fragile and dont seem to last long. The standard set up for the Gauntlet Legends/Dark Legacy is the HD mounted horizontally.
