Does anyone have the schematics for this game so I can see what I need to get for the pedals and steering wheel?

I bought a set of these boards with the extra circuit board for the controls but now I need to know what I need for the pots for the gas and brake pedals along with the steering wheel.

Any information would be greatly appreciated.

Thanks For Your Time

Did you buy them on ebay recently? If you purchased them from oregon, I could almost guarantee you those came out of my game.

At any rate, here's a couple pics of one of the pots that I kept from it:

Hope this helps you out, Sidearms.

Yes I did buy them

Yes I bought them on Ebay last week. I am looking to get the stuff so I can make a cabinet. I wanted the boards since I can never seem to find racing game boards. Now I need to try and get the rest of the components, or make the components. I'm an Electrical engineering student using this as a semester long project for one of my classes.

Any information would be greatly appreciated.

Thanks

Oh man! That must have been my old board set. The pots that go to that (which I pictured) are in most generic steering pedal assemblies that you can buy. The ones that I have still in the cabinet are the same ones Happ controls sells here:

I'm pretty sure each player had three sets of boards. There was the main PCB, which was housed in a cage, a soundboard (which was pretty small), and the steering board. All three were connected thru the wiring to one another. I will crack open my cabinet later this afternoon and see if I got lazy and left anything else. If you bought it off ebay, you probably got my boards which I gave to my buddy.
 
thanks gozer

Yeah,
I can tell you that I just bought these from a Jered. It looks as though it comes with one steering board, 2PCB's and some type of harness. I can say that I would love any information about the cabinet these came out of as I am going to be building one for at least one of the pcb's. Sounds to me like the toughest part is going to be the steering wheel. The pedals are no problem if they are just 5k pots, I can weld up a set of pedals and put the pots in there. But the steering wheel on the other hand sounds like a little different animal if it has it's own circuit board.

And the sound board, I would be it was just an amplifier board that will boost the output signal for the speakers. Most likely I can make one of those with a few opamps from Digikey.

If you have any extra parts let me know, maybe we can work something out.

Thanks
 
Cool Sidearms, I'll check the cab later today, maybe get you some pics of the interior or something too. I left the steering wheel assemblies and pedal assemblies in the cab for my xbox conversion. Start looking thru Happ controls at different styles of steering assemblies as you'll probably need one. Check thru KLOV first though when it comes time to buy. From the parts, I know I've got the two shifters available and a couple pots. I had the marquee packed away for a rainy day, but it shattered into a thousand peices when I was trying to show it to Jered. :(

Expect an update to this thread around 6 pm. Here's a the cab ended up after the xbox conversion:

Awesome Cab

Man that was sweet. I will eventually be building something like that for my PS3 once they come out with Forza (the full length version). Until then, I will be working on this cabinet for my school work. And let me tell you, any information and parts would be greatly appreciated.

If you would like, I can PM my phone number if it's easier.

Lastly,
Cute little girl with the arcade machine. I'd bet that's the little one?

Thanks, I'll stop back about 8:00 CST.

Really Appreciate all the info.
 
Yup, that's my little one.
I had a brief minute to snap open the back doors to the cabinet and look at setup that is left. From what I can see, it looks like each player had his own setup, which not only consisted of all three boards you got, but also a standard power supply, a transformer,and a couple other wires. Check the pictures:

picture.php

This is what the compartment looked like in the back of player 2 side. You can see, there's the transformer which sends a couple wires over to the power supply, as well as a 5-pin molex bundle which connects to the smaller board (sound I think). At any rate, only four of the five pins are used.
picture.php

Jeez, I marked some of the wires, but didn't document any pictures to show how they were setup. At the time, I was thinking if the XBOX thing didn't work, I was just gonna put it all back together.
picture.php

As you can see, Player 1 side had the same 5-pin molex pinout which was removed from the seperate smaller board. Look on the smaller boards you got. Whichever one had the 5-pin prongs on it, is the one that is supposed to have this power.

So in theory, you should have received from Jered:
1. There should be a seperate set of wires which connect player one to player two for competitions.
2. You should have the MAIN harness, which connects to the MAIN pcb pins and will have some ground, -5, +5, and +12V wires that go to the power supply.
3. Also in this main harness should be a bundle of wires which head up towards the monitor. Will probably have a small 3 wire molex and a small 4 wire molex. These look standard, so you will recognize them.
4. Also in the main harness will be wires which go up to buttons and pedals.
5. And if memory serves me right, there were some wires which came from the main harness and attached to a set of pins on the steering boards (they might be 2 red wires or something.) Then, some other wires from the steering board went up to the actual pots on the wheel.
6. There is probably some sound wires which come from the main harness and attach to the sound board which is then wired to transformer.

Like I said, it was a while ago, so my memory is a bit fuzzy on the wiring. I've got so many wires all over the place in there now, that it is very hard to see what I'm doing. Actually, if you're lucky, I think I tried to tag what each section of wires went to on atleast one of the harness setups. Hopefully you received it all with those still intact. I'll wait to see what you find out.

I still have not received the parts as of yet, however, I'm getting everything that I can prepared so once I get them I can get a really good quick start.

Those pictures are absolutely perfect for what I'm going to need. I did notice in the pictures that there were some type of blue tags (tape) on the harness and so it's hard to say. Looks to be the exact same as the tape you are showing me with the information written.

I can't wait to get this project rolling. I've been waiting to get a good sit down style racer for many years and finally am getting started. I'll be making a single cab from scratch, using a real racing seat, and hopefully a nice steering wheel. The wheel will depend on the money situation for now. Then in the future I will make the last half to the cab and setup the side by side play.

Have you thought about the shifters and spare parts you may have?
 
Oops

Forgot to ask, you made the comment that the steering wheel had a pot, but does it have to be a force feedback type, or would a regular pot work?
 
yeah, that'll be cool to get that going man! I was originally going to custom build my own racing cab for an xbox, then dropped it when I realized I wouldn't have the time to build the cab. Fortunately, my buddy found this cab and only wanted the 25" monitors in it. Perfect for me seeing how I was going to gut them and get 25" tvs for the xbox's. The rest is history.

AS far as the parts. Not sure what I can get you. I know I have one of the pots left from the pedal assembly, which you can just have. The pots are still being used for steering, so that's out of the runnin'. The other pots must have grown legs and walked away, because there not at my house anymore. But from the one, you'll be able to figure out what you need. However, if you buy the one from happ controls, it will already have them with it.

I'll check with my buddy who took the monitors (sign on name oregonarcade), and see if he has the shifters laying around. They are high/ low shifters, just like Pole Position. They're technically his now, so I'll see if we can get em over to your house for cheap.

Hopefully you don't want the transformers? They weigh a shitload and would probably cost a few bucks to ship.
 
hopefully this helps you too. I found some of the pictures I snapped before I removed some of the wiring.

This shows the wires sitting on the gas pedal pot.

These are some wires which were attached to the shifter switch.

And finally, this is what the back of the steering column looked like with the wiring attached to the steering pot. You can also see the button wiring for player 2 as well. There was a start button and a "turbo" button, but to my recollection, there was no turbo in this game, the switch was useless.

Got them

Gozer,
Got your parts today. They are in really great shape. All the harnesses have the tape with what they are, but, small circuit boards are for?

The circuit boards are HUGE. I've never seen a setup like that in my life.

You don't know what type of switching power supply this used, do you?

Thanks
Justin
 
yeah, I'm really not even sure which little board did what now. At one point in time, when it was all wired together here at my house, I probably could have told you. They must be a sound board and I think another one for steering. Send me a picture of the different boards to jog my memory. I haven't seen those since I removed them in February.

Ha! I know those cages housed a ton of stuff! But the good thing is that you'll never need to open them and monkey with it, all the settings are setup correctly. Just make sure you have the Player One hooked up to your setup.

When I got the cabinet it was all hotwired already. The dude had two big beast Power supplies like this:

One was for lights only, and I believe the other one was then spliced and taken to each of the two player's transformers which then went back to the standard switching power supply setups like this:

Pretty ghetto, I'm sure. Quite possible not how it was intended to work. But never the less, it did work as you can see by the gameplay video on my youtube. Quite possibly one of these beast power supplies may have powered a something else in the cabinet as well. When I cracked open the area under the seats, there were two motors of some sort with fans attached, sitting there without wires hooked to them. Quite possible the were shaker motors. Not telling for sure.

The boards look like this:

Here are what the boards look like, both are the same:

Well,
I can't seem to get the image to load correctly, sorry.

I can say that it has 1 LARGE Capacitor and 1 Very BIG square (finned)Element, and 1 large heat sink

Also it has 2 connectors on 2 sides of the board.

man, the picture would help jog my memory. I'll PM my email to you, then you can send it to me that way, eh?
