It's not an official fan club, but it was the start of "something"

What are you getting on the voltage test points? You have a break in power somewhere between the 5v light and the cpu, but it could be cold solder on the cpu. Or something else simple. Especially if the guy said he had been doing some board work. My main assumption would be that he messed it up and his work needs to be redone.
Edit: it looks like you have posted most of the test points having correct voltage. Did you already check that diode and resistor? I still assume his work is the issue.

For $200 or less, you should be able to have your original MPU and power supply repaired.

#54 4 years ago
Quoted from DocRotCod:

Look how many guys offered to help fix your original board. Look how many people would step up to fix an aftermarket board. It's the same reason I prefer a original MM over a remake.

Bingo. Some time in the future, we'll need to be repairing these aftermarket boards, but not quite yet.

Easily less than $200.
The general base rate for System 11 MPU repair is $84.

The diode and resistor are on the power board and have not been tested (was mainly tracking the 5v) I believe all the work he did was on the power board and not on the mpu.

At $84 I will definitely be looking to get the original board repaired - maybe after xmas.

That is what I was thinking. Maybe the ground or bad rom/cpu sockets

#59 4 years ago

One question that I did have is where does this board get its clock signal? does it originate in the 6802?

#60 4 years ago

Well the +100 measures out at a whopping 7.7 I can see the previous owners handi-work here on the power board. I think he just tried to re-flow

It's not uncommon for the HV section to fail.
I'd definitely get that board repaired as they are much more reliable than RD power supplies are. If you go aftermarket, XPin is a good one.

That PS board has seen prior rework. The 2 1/2 watt resistors don't match - R3 has been replaced.

R3 and R4 are common failures on this circuit. Often times, they are all it takes to get the circuit working properly again - but I usually do the entire HV section, one of the few times I shotgun anything.

I don't see any original Sys11 board of any flavor selling for $300 - that seems a bit high to me. I buy, sell and repair quite a few, so I think I've got a pretty decent handle on value. I'd say an original Sys11 MPU, clean, is a 250-275 board on a good day.

#63 4 years ago

Word.

Quoted from johnwartjr:

So you will give me $250 for my clean gently used board? Today is after all a good day!

#65 4 years ago
Quoted from shacklersrevenge:

please do not part Pool Sharks, I have seen far too many parted on ebay and production was fairly low, and I think it's a very underrated and fun machine.

Werd. Played a lot of pins in my youth and somehow never played this one until a few weeks back. Wish I'd known about this one sooner.

"Awwwwww scratch!"

#66 4 years ago
Quoted from Daddy-o:

The sys11c board used in pool sharks is not a clean original sys11 board. The original sys11 board is much harder to find than an 11c, and much more versatile.

And that's the price I would be selling one for - 100% working and repaired, with a guarantee. That means I'd be buying for a significant amount less.

#67 4 years ago

While I am in a waiting pattern, I think I will replace this diode that is burned (D-39) what all does an aux. power driver board do? flashing lights, solenoids, does it also do anything with the displays?

photo (41).JPG
#68 4 years ago

Had a little time this am, so I popped a new diode into 39. The old one did test bad when I got it out. I also noticed more work. The resistor on the interconnect board that controls the flashers is fried. and this is how the back of the aux. power driver looks (behind the relay) What a mess!! what is this thing and is it supposed to be there??

photo (42).JPG

#69 4 years ago

Looks like a capacitor, not supposed to be there. Nice to hear that you are finding fried components, that means progress.

#70 4 years ago

Could be a cap like mentioned. Someone might have put it there to abate arcing of the relay points. Not needed, but not a terrible idea.

Just a terrible job soldering Should I just cut it off?

Got my new Rottendog boards installed today. New mpu and power supply. Flipped the switch and it fired up like a champ. Looks like everything works as it should (except for the talking shark that has broken linkage. I am using my original game roms, so whatever was wrong with my old board was not the 6802 or roms. I was a little worried that the boards might require some work or jumpers to get them in, but they were totally "plug and play"

#74 4 years ago

Congrats on getting it running! Don't know if I have ever played that game, what do you think of it?

#75 4 years ago

Thanks Steve! We thought it was going to be a slow game without a multi-ball, but we are really enjoying it. New rubber throughout and copious amounts of paste wax and the ball really flies. Took a bit to figure out the gameplay. When you start a game, you can either play 8 or 9 ball billiards and when you play nine ball you are supposed to sink the balls in numerical order. The issue is nothing on the playfield is marked ball 1,2,3, etc...then we figured out that it is the blinking drop target that scores the ball you need. Other than that, cheesy music and a talking shark. and girls, girls, girls. If you are ever in Redwood City, give a shout and you are more than welcome to play.

Daddy-O I'm thrilled to see you got this running. Now I need an excuse to get there and play it.

Thanks! Its funny how fast a $100 dollar machine can become a $500 dollar machine. My garage door is always open - Just bring quarters - lots and lots of quarters

#78 4 years ago

Who needs quarters if you have the keys!

At $500 you are still way ahead. I would love to drop by sometime.

#80 4 years ago

Glad you got it working! You should be able to sell your boards as well to bring that number down to more like $400.

I guess if the price was right, I might sell them. The power supply was definitely a hack job by the previous owner but the mpu looks very clean/untouched and I would really like to see it running. Right now it is a symbol of defeat. I have an old computer that I may rip the power supply out of and set up a test bench or just send it out. But for now I removed the batteries and packed it away. I need to focus on other things til xmas.

The PSU doesn't look bad. $15 of parts and about 30 minutes would get that PSU back to brand-new shape.

That MPU is questionable, as is always the case with battery leakage. It could be as simple as a few socket replacements, or as horrible as full-blown multiple IC/component removal/replacement and trace damage repair all over. If someone is giving you a flat rate of $85 for the repair, do it, that's a great deal.

No, I was trying to send a pm with a couple of pics. and could not figure out how. So I just added them to the thread. Look Ma! no acid damage. Happy Thanksgiving!

#89 4 years ago

Ha! Yeah, the one thing that the pinside mail is sorely lacking is the ability to send pics, you have to exchange real emails with someone, or link them from somewhere.

#90 4 years ago

Depending on price, I might be interested in your non-working boards. Can always use spares!

I am planning on getting the mpu running before I do anything with it.
