Title: NPs Paperboy Restoration
Post by: Neverending Project on September 02, 2008, 08:07:37 pm
I found a Paperboy on my local Craigslist. At first I tried to ignore it - I mean I don't need any more projects at the moment... I already have 1 unfinished MAME cabinet, 2 non-working pinballs, and 1 non-working pachinko machine all trying to get my attention. But after a couple of days the ad started calling to me from the back of my mind. I decided for $75 I needed to take a look. A relatively short drive and $65 later, I have yet another project to add to my unfinished board.

The machine is in need of restoration, but it is one of those situations where the guy said that it worked fine except some of the sprites (like the race car) were invisible. Then after someone came out to take a look at it, it never worked again. I don't really buy it, cause after I tool a look at the hack job on the power suply, I think someone attempted to do more than just fix it.

Here is the cabinet:
(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=107834;image)

It is in decent shape, but needs some internal reinforcing. The sides will need some bondo, new paint and artwork. Here is the CP:
(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=107836;image)

It is a little loose, but not from loose bolts. I think the metal frame that holds the pots is broken. Maybe I can have someone weld it back together.

More in a bit...
Title: More initial info
Post by: Neverending Project on September 02, 2008, 08:13:01 pm
So someone did a hack job to try to bypass the original power supply. There is no switching power supply as I might think, but instead a duct-tape job splicing two wires (the white and pink) to a female AC power cord!

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=107840;image)

My guess is they used a computer power supply somehow, but it is now missing. There is no way this thing was recently working. But I have a question. Where is a good place to find a manual showing voltages and such? Also, does anyone know what voltages should be supplied here (on the top connector?
(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=107838;image)
Also, notice connectors J16 and J103 are missing - is this normal?

I have a switching power supply that I may be able to use, depending on what voltages this thing needs.

Frizzle - I will be looking to you for advice. Please pave the way so my job might be easier!


Also, see attached for a dude that came along for the ride.

Great, thank you! Browsing through the manual I noticed first off that the 5V supply is missing (that explains what was on the wood mounting strips in the above picture). So best I can tell, either the brown or red wires (or both) 5V.

I see that someone is offering a Paperboy schematic package on eBay - does anyone know of an online source for these also?

Right now it seems the easiest fix will be to add a switching power supply (easier than rebuilding the power supplies and voltage regulator).

Title: Step 1: The Power Supply
Post by: Neverending Project on September 05, 2008, 12:36:35 am
First I need to find out what shape the power supply is in. By the looks of it (and the looks of the interior of the cabinet) something fuzzy has been making its home here.

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=107997;image)

So after a bit of clean-up, this is what I am left with:

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=51525.0;attach=108001;image)

I would love to tell you the good news that all the voltages look good. The problem is that all the fuses are slow-blow, of which I have none. My local auto-parts store doesn't seem to carry the slow-blow fuses, so it's off the the land of shipping charges that I go. I did manage to find one fuse in the cabinet that is rated correctly, and still good.

Ah well, slow start I suppose.
Title: Re: YAPR (Yet Another Paperboy Restoration)
Post by: Neverending Project on September 05, 2008, 02:02:25 am
So I am sitting there watching Purple Rain (because it was on, that's why), and it dawned on me that I had some 4A slow-blow that I ordered for my pins. I had enough, so I stuck a 10A slow in place of the 7A just so I could test the voltages.
 :blowup:

No, nothing blew up. I just always wanted to use that smiley.

But the output that was supposed to have 10.3VDC was reading almost 15VDC. Now, do you think this is because:
a) Big Blue needs to be replaced
b) the rectifier needs to be replaced
c) there is no load on the power supply
d) all of the above
e) none of the above
f) some of the above

Time's up, please put down your pencils.

Oh wait, I still need some advice... pick up those pencils again please. Hey, you, ChadTower... stop looking at Q*Bert's answers!

Big Blue always needs replacing if you can't vouch for it.  If it's dead it will not be smoothing out the current flow and that pounds on everything down the line.  Especially on an Atari cab, don't even think about it, replace Big Blue.

Did you check the BRs?  They could be dead too.  Use the diode check on your DMM.  If you don't know how to test a BR yet now is the time to learn as you'll need that a lot for your pins too.  Marvin3M has a great section on that someplace.  Where are the BRs?  I don't see any in that picture.

Take an AC reading on the 10.3v line.  There shouldn't be any but if there is you know you've got AC ripple which points right at both the Big Blue and

I just noticed that there are two giant 27000mfd capacitors - the one here on the PS, and a second one right after the PS (both can be seen in the second pic in reply#1 above). It is the same lines that run through the first cap. Which one is technically big blue? I guess they should both be replaced?

There is only one BR on the PS, and it is mounted underneath. I will check that as well. Thanks.

Yeah, swap them both.  Pretty much all caps with any real size to them.
Title: Troubleshooting 101
Post by: Neverending Project on September 09, 2008, 12:45:11 am
We have a game! Well, almost...

I hooked up an old switching power supply that I had to supply the +5V for the CPU, and the +12V for the fan. I hooked everything else up, and the game seems to play fine. The problem is the video is completely jumbled, and I'm not sure where to begin my troubleshooting.

I have checked the voltages with the game running, and the 5V test points are at 5V and 5.5V, and the 10.3 test point is at 11.5V. I ran the self-tests and from what I can tell there are no RAM/ROM errors, since it proceeds right to the 6502 tests, and then to the tones. If there are RAM/ROM errors it will display an error page with the location of the bad ROM. Even though I can't read the screen, I can tell it progresses through all the tests.

Here is a video with the game playing. What do you think I should check first?

Title: Re: NPs Paperboy Restoration - Help Needed (video added)
Post by: Neverending Project on September 09, 2008, 07:56:31 pm
OK, I think I got the video uploaded correctly this time, and it should appear in the above post soon. So does anyone have any suggestions to what I should check first?
Title: Is it really a voltage problem?
Post by: Neverending Project on September 15, 2008, 11:24:04 am
I have re-seated all the socketed ICs on both the CPU and the Video PCBs. I thought I found a chip that was incorrectly inserted, but my problem still remains. The 5V voltages look good on all the 5V test points I can find, and at pin 1 of a couple of random ICs that I tested. The only voltage I that doesn't seem right is the test point on the Audio/Regulator board - it should be 10.3V and is reading 11.5V.

So I plan on replacing the Big Blue cap(s) and rebuilding the Audio/Regulator board. But my question is, does this really seem like a voltage problem?

Running through the in-game test screens again, I ran into what must be a clue. On the attached picture, the picture should show the numbers 0-9, and then letters A-Z in yellow. Then they are repeated again in blue. According to the manual:
Quote
The Alphanumeric Test screen displays the condition of the alphanumeric ROM, alphanumeric color palettes, and associated circuitry. The displayed alphanumeric characters should be repeated twice with the first set yellow and the second set blue with red specks. If first set of characters is yellow and the second set is not blue, then there may be a problem with the color palette select circuits.

If you look closely, you will see the numbers 0-9, and then the character A, but then the rest is jumbled. It seems as this should tell me there is either something wrong with a RAM chip, or possiblly the ROM in the game? But then again, I have no idea what I am doing... so I ask you - could this be a voltage problem, or should I consider replacing the RAM chips?

I'd make sure the RAM is getting proper voltages first... slight undervoltages can cause inconsistent RAM behaviour, I think.

Without a scope, what is the best way to check these? If I am understanding the schematic correctly, the RAM chips (6116) do not have a +5V line - they read/write when the signal lines are high (or low, depending on the signal). So without a scope, I could only check that there is activity on the line - not what the voltage is, am I correct?

I could check the +5V at the processor chip, anywhere else (besides the test points)? Also, what would be considered slight?

Attached is a pic of one of the 6116 circuits to explain what I am talking about.

Not all pins are accounted for in that schematic. There has to be a supply pin. Either check the complete board schematic or pull up a datasheet on the chip from the internet.

6116 have a GND and VCC.  Pin 24 is VCC and Pin 12 GND.  Sometimes when you draw schematics, you don't actually draw the power connections, it's just assumed.

What would really be helpful for you is to find someone else with a System 2 setup to test your boards?  Just to make sure the board is at fault.

Good to know. Since some of the ICs in the schematics listed +5V, I assumed they all would. The funny thing is I tried to google the schematic for the chip, only to return page after page of crappy sites selling datasheets. But when I just checked again using the term "6116 datasheet" instead of "6116 pinout" or "6116 schematic" it was the first link.

Excellent, thanks for the info. I will check these voltages. And I will keep my eye out for a System 2 around me - it would be helpful indeed.

All the 6116s have 4.98V between pins 12 and 24. I guess next up will be to check the voltage at each ROM chip. I suppose one could still be bad, though.

Is it even possible to replace only one ROM chip, assuming I could find a replacement or figure out how to burn a new one? Hmm, come to think of it, how would I find out what would need to be burned on each chip?

The only replacement Paperboy boards I have seen are in the neighborhood of $200, and it is not a neighborhood I was hoping to take this cab to.

If your RAM chips are socketed...pop them out and move them around... see if the defect changes.

Keep in mind that the MAME dumps aren't always the version of code you have.

Use your EPROM programmer to read the ROMs/EPROMs and use ROMIDENT to see if they are good and what version they are. If they show up as unknown then run the checksum ROMIDENT gives you through Google to see if you get a match somewhere else.

If all show good and known to ROMIDENT except for 1 or 2 then you know you have 1 or 2 bad ROMs.

That's something I always check when repairing game boards.

Doesn't the test screen indicate any ROM/RAM errors.

Not always. Test screens indicate RAM / ROM errors but you have to be careful in that most games won't test every single ROM. Some do, many do not. The ones that are usually left out are the video graphic ROMs.
Title: Re: NPs Paperboy Restoration - RAM or voltage problem?
Post by: Neverending Project on September 22, 2008, 03:37:34 pm
No luck on finding anything by changing the RAMs around. The test screen does not report any RAM errors, but I went ahead and "rotated" a, existing 6116 chip through each of the other 6116 sockets. The problem is always the same. So I am fairly confident that there is nothing wrong with the RAM chips at this point.

My gut feeling is that there is some sort of address bus issue. My second thought is a ROM issue. I can't imagine that one of the ROMs would have gone bad and the game would still play - but I haven't ruled it out.

I haven't yet figured out a way to test the address bus, but my theory is that if there is a problem with one channel, all the data being carried over the bus would be scrambled. To test the ROMs I suppose I can get an EPROM programmer. But then again, the test screen should test the ROMs too.

I wish I had another Paperboy board to test. At least I could absolutely narrow down the problem to the video or CPU board. I'm always on the lookout, though.

As a last resort, Frizzle - if you're reading this, would you test the board out for me in your cabinet if I shipped it to you?

Why don't you get a logic probe and start learning how to use it?

Get one with audio, like eBay item 110292577891

That's the same thing as the Knight 610B that I've used in repairing a LOT of video game boards. It's my #2 test tool behind my continuity tester.

Post by: Neverending Project on September 25, 2008, 10:44:30 am
Looks like a good deal. Could you give me some tips on where to start looking? My first thought is to check the bus between the CPU and video PCBs. From there, I might see if I can make the tune from Raiders of the Lost Ark by sticking the probe around random parts of the cabinet...  :dizzy:

Thanks for all the help everyony, by the way. I really appreciate it.  :cheers:

Just a quick update here... I bought FrizzleFried's non-working board set off of him, with hopes to make a working set between his and my boards. It was actually easier than I could imagine. When I tried his video board with my CPU board, the game works perfectly! If I get some time, I may go and check the ROM chips on my non-working board, to see what is wrong with it... but for now, I can move on with the restoration.

Things left to do:
Adjust the convergence (the blue appears to be out)
Find someone to weld the broken handlebar assembly
Replace grips and handlebar overlay
Replace CPO (this will involve finishing my trace and scan, to have a repro CPO made)
Bondo some holes in the cabinet
New sideart
Other stuff I'll find along the way

It may be a while before I get a chance to work on it again, but as soon as I fix the handlebars at least I have a working game!

Thanks Frizzle!

Glad you have a working game though! My defender boards are working as of today too! Now I just need to get them back from RetroACTIVE and I'll be able to play. :)

I'm sure TheShanMan can take care of it for you.

If not, I'd clean it up and JB Weld it.
Title: Re: NPs Paperboy Restoration - Video Board Replaced
Post by: TheShanMan on October 22, 2008, 08:52:51 am
I'm not that great at filling in gaps. I'd probably need to lay a little strip of metal over the top of the gap to get a decent weld. But actually JB Weld might not be a bad idea - I can't tell for sure, but I'm guessing that force applied to the handlebars (e.g. hanging on them) wouldn't particularly affect that spot.

I'd be glad to have a go at it if you want though.
Title: Re: NPs Paperboy Restoration - Video Board Replaced
Post by: Neverending Project on October 27, 2008, 03:25:39 pm
I had never heard of JB Weld. It looks like this may be exactly what it needs. At first, I though the bracket was a separate piece from the flat plate (where the spacer is), but upon closer inspection, it looks like they were welded at one point, and not supposed to separate like I thought. This means that i can simply attach the bracket to the flat plate where the crack was, and not have to work about disassembly first.

Anyway, I am trying some JB Weld today. I will let you know soon (tomorrow, most likely) if it holds. Thanks for the tip!
Title: Re: NPs Paperboy Restoration - Video Board Replaced
Post by: Neverending Project on October 28, 2008, 10:06:58 pm
The JB Weld didn't hold. I tried cleaning the surfaces with a wire brush on a dremel, but I imagine that I will need to grind the plate down for a really good surface. Considering I don't have a grinder (nor can I weld), I guess it's back to plan B. Or was that plan A...

Handlebars welded! I'm no professional welder, so the weld doesn't look particularly beautiful, but the only thing that really matters is that it's now a solid unit.

Note: in picture 2 I didn't want to do anything to that spring hooking mechanism, so as you can see I didn't weld near it. That shouldn't have any effect on durability though.

There is 3.5" across (front-to-back) in the hole that the handlebars sit in. I am pretty sure it will fit fine. I can't wait to get these back in the cabinet!

Post by: Neverending Project on January 12, 2009, 04:31:10 pm
Well, have made some minor progress lately. Nothing to write home about, though.

I ordered some white vinyl and found the Atari System 2 sideart, so I ordered that as well. The vinyl came from thisoldgame, which happens to be right here in Oregon City! So I was able to stop by and pick that up. I haven't installed it yet though, cause I will need to do some bondo work first. I haven't heard back from the sideart yet, so I need to follow up on that.

And while I was at it, I decided to have a go at cleaning the CP again. It was so dirty that you couldn't tell the difference between the white, and the white with the "half-tone" to make it look shaded. And the colors were so filthy that you really couldn't tell what the original colors were. But the first time I tried to clean in I used some serious elbow grease, including tools like toothbrushes, scrubbers and scour pads. And I tried non-toxic cleaners like 409 and goo-gone. But in the end none of it made any difference, so I figured I would have to replace the overlay (That's when I started my tracing project).

But I had another go last weekend with a Magic Eraser, and talk about magic! It actually cleaned it so well that I am thinking about not replacing it at all! Or at least moving the priority of CPO replacement way down. It looks like someone did some black spray painting at one point, cause there are black speckles on it that won't come off. But all-in-all, I am going to file this one in the good-enough-for-now category. I have pics, but haven't dumped my camera yet.

I also checked out the controller again, and am going to replace the pots. The gameplay seemed funky to me, and taking a dmm to the pots showed me they are shot. So I will order a couple from mouser and replace those as well.

And that reminds me - anyone reading this who has a Paperboy controller, do you have much (or any) in/out motion in your controller. I am not talking about pushing forward to back to go fast/slow, but if you were to pull up on the handlebars, do they move at all? I might be missing a washer on the shaft, and I seem to have about 1/8" travel or "play."

Anyway, I will try to get CP before and after pics posted soon.

Look forward to the pics. I heard about Magic Eraser recently too, on KLOV I think. I want to pick some up and see just how good it is. Did you get some locally? If so, where?

As for the pots, did you try using some contact cleaner on them? Maybe you can get 'em working without having to replace them?

I knew ThisOldGame was here locally, but I've never been there. So I take it you got to meet Richard? I've had some online discussions with him but that's it so far.

Anyway, you may say it's nothing to write home about, but getting it all cleaned up is a big thing in my book. Congrats on the progress!

As promised, evidence of the magic of the Magic Eraser:

Oh, and you can find the Magic Erasers anywhere they sell cleaning stuff. I got mine at Home Depot even.

Very nice! I'll be picking some up next time I make it to HD.

Another small update. I got some replacement 5K pots from Mouser and replaced the two pots in the handlebars. I had to file my own flat spot on the shaft, so it wasn't exactly in the center - or more accurately, if you turned the pot to 2.5K, my flat spot was about 10-15 degrees off from the pots I replaced. Normally this wouldn't be a problem because it doesn't really matter at what angle I attach the small spur gear. But on one of the pots, it turned out to be a bad coincidence. The set screw would hit the mounting bracket in one direction, preventing full movement. Fortunately I was able to just turn the pot and spur gear and reinstall. Then I could run the calibration in the test menu and all was good.

I am happy to report that the game plays great now. Still left to be done:
*Optional, and quite frankly may not be done for a long time...

I finally have an update to report on this restoration. I have had the white vinyl and the System 2 sideart for a while now, but I have just been waiting for the weather, my time, and my motivation to align so I could get some work done. Well recently everything was in order, so I pulled the Paperboy into the garage to get some bondo work done. I filled the gaping holes on the edges of the cabinet using the existing t-molding as my mold. Once the bondo set, I pulled off the old t-molding and sanded. After a second round of bond and some spackle for the pock marks, this is what it looked like:
Before:

(http://forum.arcadecontrols.com/index.php?action=dlattach;topic=84047.0;attach=121512;image)

Then I brought it back in to the playroom gameroom and applied the white vinyl, followed by the art and t-molding. The white vinyl went on great without any problems. Unfortunately, I had all sorts of bubbles with the side art. I took my time, removed the backing slowly, and smoothed as I went only uncovering an inch or two at a time. But still it was riddled with bubbles. Here is in progress installing the art:

And here it is with one side done.

Note the close-up of all the bubbles. I popped a bunch, but before I do the other side, can I apply this side art with some liquid so I can squeege out the bubbles? It is really unfortunate to botch such a potentially great resto job with bubbly side-art.

Looks nice (other than the bubbles)! You certainly picked a good time to work on it weather wise - can't believe how nice it's been here the last few days! :applaud:

I'm going to be doing the wet method for my tron inner art in the next few days. You might benefit from reading this thread at KLOV (http://forums.klov.com/showthread.php?t=57326).

Click search above... I'm not sure what terms, but applying side art with water and light soap is discussed a few times.
