I just got a Sorcerer and a space shuttle

Both Sys9s.

Access denied! Lol.

rotordave. Been following you for a long time. I'm just in awe of your System 11 collection...My favorites hands down!

Well done, sir.

How hard would it be to remove the head on a System 11 ? I'd like to get something to fool around with this winter,but it has to be a game, that I (beginner) can remove the head on. I have a nightmare of a staircase to maneuver this game up.

The good news is if you buy a Comet you'll be system 9 complete. Then you will be the rotordave of System 9s!

Anyway, welcome to the system 9 club (not sure we actually have one).

It's not bad at all unless someone has hacked around with the wiring.
There are several connectors to take apart, that will generally only go back together correctly.
A couple of large bolts that hold the head in place. Most system 11s also have hinges. So you have to take a couple small bolts out of the hinges once the head is folded down. Not bad at all.
I took the head off the Grand Lizard I picked up yesterday as part of moving it, and have had the heads of a couple other of my system 11 games.

You'd probably crap your pants at what I paid for my Bad Cats.

Even with everything in my collection it is the most expensive game I have ever bought. But totally worth it to me.

ISO transformer for my f14

Surprise us.

I paid a bit for my Bad Cats too. It was one of the last ones I needed - ended up getting one in the Philly area and shipping it home. Think it was $1800? Nice tidy PF and BG, cabinet is a bit faded. But it came with a nice tidy $400 Fireball 2 as well, so that sorta balanced it out.

Most I’ve paid for a Sys11 was the very nice restored Pinbot I got off pinheadpierre up near Sacramento. That was $2700 I think. New PF, the works. I already had a Pinbot but this one was much much nicer. I sold mine which subsidised a lot of the new one.

You can see the new Pinbot (and some more of my pins) in this video.

I am wondeing Grumpy if you can point me at a starting point to get my Space Station board to boot? A quick review:
- board was sent away for repair, but the repair job was less than stellar
- board would boot if I left it on for 10 minutes then re-powered on, or if I flexed the board. Everything was working once it started.
- I was trying to track down the booting issue thinking it was a cold solder issue somewhere, so I reflowed pins in the u2 / u3 area
- afterwards it won't boot at all now, and have it on bench trying to diagnose
- only 5v led comes on, not the diagnostic or blanking leds

Following the Repairng Williams System 11 Pinball guide, I have checked:
- good 5v / 12v to the board
- u25 was changed to nvram
- using logic probe, u15 pin 39 seems to react properly (both high and low lights are solid)
- grounded pin 40 of u15 to see if reset circuit resets, nothing
- checked the PIA chips by testing with DMM pins 2-17, and all read in the .4 to .8v range, and all get +5v at pin 20 when powered on
- checked u11 and u13 with DMM, pins 1-9, 11-19 seem to read fine
- replaced the 4 caps (including c30) on the mpu

What should I be checking or replacing next? Thanks in advance!

I just found this today. I am a big time System 11 fan! I currently own a Pin*Bot and High Speed. I have a buddy with a Road Kings that I really like and I'm looking at buying a Swords of Fury soon!

Guys, I'm new to Pinside and am working on my second solid state machine, a 1989 Williams Police Force. My first machine, a Bally Fireball Classic, spoiled me. All I had to do was clean it up a bit. Pretty much everything worked when I got it. This Police Force is kicking my butt. It doesn't help that I'm a novice when it comes to solid state issues. When I turn on the machine the CPU appears to power up. I get the two LED lights on the CPU steady on and the center LED blinking. The two displays are completely dead though and I'm not sure where to start looking to correct this.

Some background info:
This was originally a 220v machine that someone has converted over to 110v.
I had to replace the coin door switch and I'm not sure, when the coin door is open should the contacts in the coin door switch be open or closed. I'm thinking they should be closed? I think the schematic shows this switch to be open which it would be with the coin door closed.
With the coin door open, and contacts in coin door switch closed, and I press the SW2 test button on the CPU, I get the center LED blinking 2 times and the right LED blinking 10 times. Is this giving me a clue as to why the displays are dead? How can I check the displays to make sure they haven't gassed out?

I read in CFH's "Repairing Williams System 11 Pinball 1986-1990" (THANKS cfh) that a good thing to check for a dead display are two 39k resistors on the Power board. Setting my really cheap multi-meter to 200k ohms, I get 39.2 on one of them and 40.3 on the other. That's with the Power board sitting on the workbench. Am I correct to think they are good?

Thanks for your advice in advance,
Rick

First thing to check is the voltage supply to the displays. No volts - no work! Info should be in Clays guides you have. You need to check the high power section of the power board.

Second, check the data cable from the cpu to the display. No data - no work!

That gives you somewhere to start.

rd

Have you replaced the chip sockets for the rom chips?

No I haven't touched them (assuming you are talking about u21 and u22). Should I?

No U-26 and U-27. U-21 and U-22 are sound ROMs and will not cause this kind of issue.

Sorry, right. Not sure what I was thinking when I said that. No, they are socketed, but I didn't touch them.

elvira is gone (from time now), and pinbot just came in

Last call.

I'm looking for someone sitting on an old taxi playfield that is beyond bringing back with touch-up. I'm about to sand down an average one to hardtop it.

Anyone?

Looking for two of the Locking Cam Brackets shown in the upper drawing in the pic. Part numberr I need is: Wms. 01-9281, not the bracket in the lower drawing. Needed for Bad Cats and Jokerz! Thanks.

Thanks Dave for the advice.
I checked voltages from the power board to the main display; -100v, +100v and +5v all appear to be making it to the display.
I checked continuity on all of the strands in the data cable from the CPU to the main display and it also appears data should be getting there.
Is there anything else I can check before assuming the main display is shot?
Curious, if power and data are getting to the main display, what about the small display? It's also dead.
I know power and data passes through the main display to get to the small display but should or shouldn't I see something on the small display regardless if the main display is dead?

Another note: I just noticed that the CPU in my Police Force, game #573, appears to be out of a Whirlwind, game #574. At least that's what I'm seeing on the paper sticker on the CPU. How is that going to affect game play?

Not at all. As for your displays, did you have a good blanking signal at the display board?

Grumpy, please excuse my lack of knowledge, I'm new at this. How do I check the blanking signal?

Rick

You can check it with a voltmeter or a logic probe. If you need help with there operation, just ask. Do you have a manual? Page #86 shows you that the blanking signal leaves the CPU board on pin 2 of J-22 on the way to the display board. Page #88 is the display board and it shows that the blanking signal goes U1,U2,U5 and U6. So if you measure pin 1 of U1 on the display board after the game boots up it should read as a low on a logic probe or read 0.8 volts DC or lower on the voltmeter. If you see a high or 5 volts DC then your ribbon cable maybe bad or you may have a problem with the CPU board. To check to see if the ribbon cable is bad you can reverse both ends and retest. If this doesn't help then you need to test pin 2 of J-22 on the CPU board as a bad trace or cold solder joint on J-22 can cause this.

Thank you.

Does anyone know where I can get a ball gate assembly (left ramp part number A-13288) for Mousin Around?

Probably! Hit it with some oil free contact cleaner (always oil free! CRC make one ...) then move it rapidly left and right about 10 times.

Or replace it. $3.

Guys, thank you for your help with this machine.
After determining that both displays were bad, I sold it to a pinball arcade the other day so they can finish restoring it.
I'm sticking with my Fireball Classic.

Rick

I like the Classic.

In with GL F14 ES and WW.

I'll see your 16 sys11's and raise you 5.

Ha. Slowly but sure wins the race. Actually when I picked up the Fire the seller had a Banzai Run........I didn't even want to ask.

What, no Whirlwind?

Up to Two Sys 11 now. Prob one of the fewest owned ones and the most owned one

Game Show is my new one, will have lots of time to put into it when the weather goes to shit in the winter, fun game

Best generation of pinball. System 11!

Love the mirrored bg on RS.

To be honest. WW isn't one of my favor machines. I know i'm not odd many out but I am. So that is always further down the list of wants on my part. Don't you worry.......I'm working on it........

chris

My display is out on Diner. It has happened in the past but a quick power cycle fixed it and then the issue went away. Well, yesterday it wouldn't go away. I swear I posted in the past about this and asked about the likely fix. It was answered but now for the life of me I can't find the post. I think it was a single capacitor that was suggested to be replaced. Sound familiar to anyone?

Ah ha! I had taken a screen shot, so still have no idea what thread it was in. It looks like C30 on the MPU board is the first target. 22mfd @10V.

It's just an adolescent System 11.

Best description of System 9s there is!

Awesome
