Edit: Time to repair the machine. The new problem will be at my most recent reply.

The Story:

Almost 1 year ago, I saw this arcade machine at a garage sale, But wasn't interested.

Then about 5 months ago, I remembered it, thought "Man i should pick that up!" And searched for the person's house (Boy did that take awhile!) And eventually i found hi's house, And he still had the arcade machine.

I asked how much he wanted for it, He says "$25" I KNOW this is a killer price, So i plan to buy it, I tell him i'll pick it up sometime when i can transport it (No truck) And, Friday before last, I paid $10 to him to hold it for 30 days. Guranted ownership!

Then, me and my dad looked for some roofracks, And we bought some roofracks from a Sort-of-junk-shop And then, once the wooden roofracks were bought, We put them on the car.

The next day, (Last friday) We went out towards hi's (The arcade machine's owner's) House, (He lives about 30 miles away from where i live) And bought the arcade machine.

I also saw a boxed Super nintendo at a yard sale, (That i didn't buy since it was too expensive) But that's a different story in the May 2006 finds thread.

Once we had the arcade machine on the car, We took some pictures of it on the car. :)

I don't have the pictures of Rally X on the car ready just yet (I will update the digital pics) But after that, We went to EB, I Showed the employees a pic of the arcade machine, They were impressed, I didn't buy anything there, though.

While we (Me and my dad) were pulling out of the parking lot, The manager of EB was coming back after her lunch break, And we passed her as we were pulling out. Once we drove by her with the arcade machine on the roof, She knew we weren't kidding when we said I bought an arcade machine for $20! (Yeah, $20! that's the price i paid for it!)

The arcade machine is the only item i bought that day, But man, If it isn't worth it, what is!

When we got it home, We were unsure how the heck to get it off of the car. But, A neighbor was driving by, we asked if he could help us get it off. Soon enough, It was off the car.

Next step, Getting it upstairs.

Well that was fun (sarcasam) And now it's in my room:

Beautiful, isn't it?

I have both of the keys for it, too!

So, the next day i opened up the back with the key, Oh god, someone who was unexperienced (And uneducated) at electronics tried to fix it before.

A cord on the cables to the power board circuit is soldered to the board, So i can't take the board off, And worse, the board is off the track!

Well, I can still take the track off and put the board on it that way.

Hmm, what's this? The schematics and manual to the whole system!

http://www.fine-art-works.com/rx2.jpg

And, the folder it's in is the original one, too!

http://www.fine-art-works.com/rx3.jpg

Anyway, Yes the machine needs to be worked on, But i will get it running.

And yes, I paid $20 for it, plus gasoline, Straps, and the roofracks.

So, I'd say i have a good $40 in this machine so far.

I think i did great, And furthermore i may be able to get Three more arcade machines, If i can get ahold of the owner first (I haven't heard from him since december.. A Bad sign)

How do you think i did? :)

:-P

Cool deal! Any cab for that kind of price is awsome!
( I paid $25 for my first machine, and $14 for my second)

Cabaret style - nice. I've been wanting a Rally X (standard or cabaret) for a while now. Before I saw the picture (or the "mini" in the subject), I started cringing about putting a full-sized cab on the roof of a vehicle. I've seen this attempted twice: first time, the game rolled off the roof at the first corner, and second time, the roof caved before the car even got started.

Still, good score!

D'oh! LOL The roof-rolloff is a camcorder moment if ever there was one.

Nice score on the Rally-X, the Pac-Man that was never meant to be. There must be some weird phenomenon with Rally-X always going so cheap, I've heard a dozen stories just like this one.

Nice! Just got my first yesterday... such a cool feeling! Though mine is full sized... and I never knew anything could be that heavy!!

Let us know once it's up!

Very nice find. Welcome to the club.

OK, i replaced the power plug, The machine powers on, but the game is locked up when i turn it on.. (?)

The screen powers up, The machine powers up, and i hear some sound from the speaker when i turn it on.

I'm going to try and find this problem ASAP.

"Bump!"

I think the game board is what's bad. I'll be buying a Rally X game board off ebay to replace it.

check the voltage on the games power supply. also try the basic stuff such as reaseating + cleaning the roms..

Slate

Well, as i said earlier, i replaced the power plug, (It was really corroded..) And everything turns on, but the game is locked up when it's on. Also i put the PCB back in the track, So that's fixed.

And i checked the switches on the ROM board(s) and it's A-OK there, i also removed the ROM board(s) to get a better look at them.

So how would i go cleaning the ROM board? Just like any other board?

Those older games often freeze or lock up due to bad power. You can try incrementally increasing your +5V on the psu and see if that helps. Best done with a basic multimeter too.

Sounds a little scary to do.. Although the transformers ARE a little rusty, Though they run.

I thought it was the game board, but i Am a n00b at arcade machine troubleshooting...

You'll need a digital multimeter to test the voltage, if you don't already have one.

Where are you located?

Haven't you heard? Rally X (like Speed Buggy) is now a hard-core crackhead. To him, $20 is a friggin' fortune.

I can't say where i'm located, I prefer to keep that private for now. But i think my dad has a digtal multimeter. Or voltmeter.

As i said, the transformer is a bit rusty. Considering the previous owner kept it in hi's garage, That probably is it.

Hammy

the transformer or the main supply?

a rusty transformer is not a problem (the iso will power the monitor)

if the board is getting juice, chances are the supply is perfectly fine, it just needs trimming up to the correct level.

a digital multimeter is a MUST if you've got any cab(s), you'll get nowhere without one.

rally x is pretty old, if it's got a liniar supply, bin it and install a standard supply - will cause less trouble in future.

The transformer. The external power supply was rusted beyond use, but i replaced it.

What voltage should it need?

Hammy
06-08-2006, 01:23 PM
inside the cab.. not talking about the mains lead/stepdown/whatever is out there.

find the pinouts in amongst those documents, check the +5 between the +5v pin and ground on the edge connector, it should read about +5.2 (optimum voltage) any lower than +4.8v and any higher than +5.3v it needs adjusting.

make sure you meter is mesuring in DCV.

Slate

I won't be able to do it today (I don't have the digital multimeter) But i sdhould be able to do it tomorrow.

If it needs adjusting, how do i adjust it?

(BTW, do i have to have the arcade machine on to do this? I hope not)

Hammy
06-09-2006, 07:46 AM
yeah, it needs to be on when you measure the voltage.

and about adjusting it, there should be a trimming pot on your power supply.

Slate

I don't want to be electrocuted.. I'm thinking i'll be able to wire it up so i can measure the voltage, though..

Hammy
06-09-2006, 01:25 PM
+5v won't do anything ;) stay away from the monitor and you'll be fine.

Slate
06-09-2006, 02:03 PM
I think i'll play it safe anyways, though. Just as soon as i get the multimeter..

Edit: I was just eading the documentary, and it says about the power supply supposed to be 120V, so now i'm confused.

Hammy
06-09-2006, 02:29 PM
120vAC is the input, +5v, -5V and +12v (all DC) are the outputs

Slate
06-09-2006, 05:19 PM
OK.. LOL

Turns out i wasn't able to test it today. :/

I should be able to test it soon, though.

I think i located the Adjustment Knob. It's on the PCB, but is that where it should be?

Hammy
06-09-2006, 06:45 PM
hehe, that's the volume pot ;)

try the power supply ;)

Slate

Near the transformer? Ok..

The power supply board looks like this (or something very similar):

http://www.quarterarcade.com/img/vol0/1198_1_fs.jpg

See the 3 white round 'dials' (in the upper-half of the board)? Those are the separate adjustment pots for your 3 voltages. Put your meter probes on the "legs" (where it mounts to the board). They should all be close to their approx values, but you want to make sure the +5v one is around 5.10 - 5.15

Ah, yes, the PCB. I'm guessing that one comes from a full sized cab, Since my cab is a mini, And it only has one dial.

I'll be testing it as soon as i get the alligator clips for the multimeter. (I'm playing it safe, not doing anything with it unless it's closed)

Hammy
06-13-2006, 12:26 PM
!

for the second time, the dial on the gameboard is the volume pot!!

Slate
06-13-2006, 05:46 PM
LOL When i said "PCB" i really was meaning "PSU" But i typed "PCB" instead..

So, i was not looking on the game board, i was looking on the PSU... I KNOW the volume control is by the dip switches, But that's not where i was looking.

And, me and my dad worked on it today, and the PSU is good, The voltages are A-OK, didn't need any adjustments.

This is leaving us with the game board having a bad part, or just being messed up altogether.

So, i'm going to either buy another game board or fix this game board.

Hammy
06-13-2006, 06:38 PM
psu works, so it's a pcb fault. if i were you (with not much experiance with repair work) i'd just get another pcb, unless you are up for low level diagnostics!

Slate
06-13-2006, 09:48 PM
I'd rather fix this board, but if it can't be fixed, i'll buy another one on ebay.

Update on the PCB..

Some of those chips' pins were rusted off, And one of the chips was put in backwards!

nice find! I too recently aquired my first cab, which is the same exact cab you have (Rally-X Cabaret) but this one was converted to a Jungle King, yeah get away from the linear supply (scary looking aren't they?) but you still need to have an isolation transformer for the monitor juice. My cab wasn't anywhere near as nice as yours, but I got it cheap ($99) and local, and I enjoy projects, I'm refurbishing this one from head to toe!

waiting to see the cab on the car pics! :) I *almost* got mine into my honda's trunk with the back seats down LOL
