On the kicker of an Aztec I recently picked up...

Nice and snappy. When I removed it, the kicker couldn't get the ball out of the trough and, unable to find any explanation, I neatened it up and put it back

Power connector burns from all the acid damage. Clean up acid and replace header? Nah, let's just shove wires of a similar gauge through the melted wreckage

Impressively, the board still boots fine

I've got a similar thing on my Black Knight, but with black silicone so I'm not actually sure how big the hole is... Was a lot of fun replacing a bad transistor suspended in the middle

Nice! I did a similar thing using the credit button a previous owner installed hooked up to the upkicker on my black hole so that I didn't have to keep opening the whole game up to get a ball out while I was stress testing + diagnosing why the upkicker transistor kept failing

I've got a Sys6 driver board where they did the same thing to a random logic IC. No idea why..

People don't know that Jones plugs are plugs. Had a seller recently tell me "all the wires are soldered to the head, bring a wire cutter"

I've got the same thing on one of my system 6 driver boards. Makes me wonder, why are sockets that tall made in the first place?

I made use of one of these once when a previous person had replaced the cmos ram, but not socketed it (ugh) and lifted many traces in the process. I happened to have a tall 22 pin socket around, so I raised it up a half inch off the board, allowing me to solder from the top side as well as the bottom so I could get all the traces. Doesn't look like this was done on my other board or yours though, from what I can tell

The only problem I see in that picture is that someone installed a Williams flipper mech on one side...

At least with most hacks I can tell what they were thinking...

Bad... rollover? I'm not sure I understand what you mean

That'd be interesting... But, It's a solid state game, they're already dc. Hopefully. If not, I'm concerned.

Further observation: at first I assumed they'd moved the diodes off the coils for some reason, but then I noted that the coils still had diodes, so that couldn't be it. Then I noticed, these coils have *two* diodes on them. And they're not the right number per the parts manual, or like on my other Hot Tip. Should be a 20-300/28-400 DC, with one diode. These are 20-300/33-1500 DC. Marco shows these as having two diodes, but I can't see any reference to where these coils might be used. They seem to be the same strength, but with a weaker hold. Maybe these are parallel wound? Still doesn't explain the little diode board....

Strange. My other SS hot tip definitely doesn't have two diodes per coil. Its coil numbers match the parts manual, which is the only place I've found the coil numbers listed on older Williams SS games

Most Williams from that era used metal sleeves originally

We owe it to future generations to lower our repair quality...

They still asking $5k?

What the hell happened to that other board that made cutting it up to fix this one the better option?!

Yeah I would totally do this over installing a wire

I opened up one of my first games recently where I had had the same problem (wrong size fuse). Two years later my wrong length fuse ("just for testing!") was still hanging by two alligator clips.

This is a new one to me...

To be fair, I can't seem to locate the plug anywhere online. Will probably have to split it in two...

Looks like an improvement to me....

That round label looks a lot like one on my Gamatron, it says something about some electronic security lock, though I didn't see anything on the inside related to it. I'll try to grab a pic tonight for comparison

Maybe there's a second switch that would detect when the coin door opened, and if it was opened without turning off the alarm key, it'd go off? And the OP had matching keys on their coin doors so installed the lock disable elsewhere or something?

So they're just using the bridges as a double inoine diode to drop the voltage a bit?

I'll swap ya for the correct ones!

Do they actually work? Impressive if so.

About a third of the connectors have screws like this... IMG_20180818_170713 (resized).jpg

But this was my favorite

I had a future spa where every single drop had q-tips hot glued to it to hold them together. Played fine

Yeah, who needs lighting effects

I had a Blue Chip one time where they'd installed a switch on the front of the machine, below the shooter rod... despite there being a power switch directly below it on the bottom. I asked the seller and they said they knew about the power switch, but didn't feel like bending down to hit it, so they drilled a hole in the front and installed another there

There are no screws on dead bumper caps. Any time you see any screw on there, that's an operator 'hack'

Many caps I've seen don't have those side holes. I think people just drilled them. The stock bodies don't have holes for them either

There's a service bulletin for early sterns to add a fuse there. That's not a stern, but I assume the same issue applied

Originally these were in top of each other, sandwiching the plastic in place, but they vibrated loose in transit.

If you're going to ruin your playfield, seems like it'd have been way more effective to add mini posts above the outlanes

Party Animal

Harlem maybe?

I've got a board in one of my EMs that seems to be semi-programmable via jumper wires. It's got a giant grid of holes that someone has hand jumped shut in some way, and it can make a variety of simple synth sounds, but not just one-off things. Some even have their own patterns, or can play little multi-note tunes. All done without a CPU somehow. Wish I had a manual

Most early PCBs I've seen look the same. Don't think it's home made, just hand plotted

Many games like Segas do heat up quickly when playing long games. It seems to be caused by using single wound coils instead of dual wound, or adding big filter caps to the power supplies. WPC don't have the issue that much but any manufacturer that doesn't recreate the exact systems that williams used tends to have issues or weak flippers

Even those coils get hot after a long game and lose power...

Maybe it was meant to have the rectifiers mounted on the other side?

"63 known to exist, 8 people want one" would be more accurate given the data...
