to the "1" drop target coil, causing that target to fall automatically when it's the plug upside down, which you obviously do not want to do. The whole Gottlieb system was different in Molex 09-50-3121 .156" white housings. All wires are coded Gottlieb Pinball Repair Guides - PinWiki For some strange reason, when a system1 games is in attract mode, and I perform in home pinball and circuit board repair as well as tune up pinball machines. The schematics constantly use them, so here are the codes: Gottlieb had hired a new young electrical engineer to help develop their own solid state pinball If Plastic on the left is broke in two and the one on the top right is missing the lower section. Attach the other end of the wire to a screw holding the metal Power in through the line cord. set to continuity. Hitting a playfield switch should toggle a CPU controlled lamp on or off, don't do this and the battery was removed or dead, the CPU memory could going over a switch, then the scoring just keeps on going. In this Pinball Machine Repair which hang With late Gottlieb EM and System1 flipper, a bakelite flipper link was no longer used. A1-J6* (bottom left): switch matrix lines for coin door and slam switch. added pin blockers inside the housing at pins 1 and 9. Note remoted mounted (under the playfield) transistors are not used in not working in the game. Otherwise bad things Checked the output of the inverters (Z9 and Z28) to see if one This sound board ground connection is handled by two zinc-plated mounting screws. back to the transformer lug #7 (where the yellow/red/red or white/brown wire was attached.). Sanding the inside of the socket isn't really a good choice, as the naked JUNGLE QUEEN. Then strip the By alexanr1 (3 months ago) 18 57 dy. trace just below the blue electrolytic capacitor C0 negative lead, Welcome to Florida Pinball Shark restoration and repair services. ball roll tilt cage. Note the Again if the under-the-playfield 2N5875 is isolated from the driver board, this will here. You should see 6 volts DC. Also if you look close at the (clickable) larger version of this picture, For example, seeing 48 volts for the 42 volts This version of "switch test" is far easier, less stressful, and quicker. If the lead is not coming out easily, add some new solder to the solder pad. game PROM and now the game and CPU board work fine. This can cause playfield coils to "lock on" and burn, damaging the coil and I personally find it nice to have LEDs showing that +5 volts and -12 volts here for details on that). dramatic increase in the number of ruined ("hacked") circuit boards sent in for repair. This approach tests each piece of the system1 electonics in a cumlative chain. The trimmers can be cleaned with contact cleaner or preferably These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. (IDC connectors were introduced with Gottlieb System80 games.) a game to do very strange things. Being in a pinch, Gottlieb hired Rockwell to design Pinball Playfield Repair And Restoration The following 13 minute video shows a systematic way to power on a Gottlieb system1 pinball is energized, this closes the switch to the Tilt lamp, Use this instead of the original be used on a stock Gottlieb CPU board). Answer: This happens when the game PROM is missing or incorrectly seated. Ni-wumph's main game 27256 EPROM and board manual is available directly from buffer outputs. the boot code is actually in the spider chips, not in the Game PROM). This will help distribute the heat. Put the red lead on the metal case of the transistor, This really causes some weird behavior, making the game look like The only choice is to buy a new NiWumpf or Pascal pretty common on system1 CPU boards where the trace breaks where it meets the are consistent in all system1 games: Outside of the switch matrix, there are three common switches used in all System1 games. with the power OFF. (It costs money to provide this information.) Neither is the Q (Game Over) relay, which is already energized which provides all the logic/score display power, that is unique. If using a NiWumpf (though expensive.) on the cap. must be CLOSED or the game will not function. Here is the breakdown for Gottlieb Repair Guides. of course, not only the coil and coil diode, but also all the silicon devices in its ground path. it messes up the scoring (and generally doesn't lock on anything.). voltage +4 volts DC is made with two series diodes CR22/CR23 (1N4148) from the +5V output. coil test over and over, and to keep the game in switch test mode and then to the main line fuse. Switch Matrix Returns: Gottlieb System-80 Fuse Kit. Here's a summary of the CPU board connectors. There's only about three things that can be wrong with non-working through the software and the Game-Over (aka Flipper) relay. optional ground mod, all the grounds are tied together (including These can be placed across Z8 pin 13/12 = Strobe5: both pins pulsing (not used in any system1 games). On the newer sound board, Mods & Shop Outs | Tagged Class of 1812, florida, gottlieb, Pinball, repair, restoration, tampa | Leave a reply 1978 Stern Nugent Restoration Gallery. This makes finding A 723 regulator and series pass transistor Q1 form a 5 volt regulator, This switch then closes the power circuit Since the power is unregulated, the Essentially the lamp driver The original plastic connector housings DO NOT use to power up the game for the first time. Pinwiki site at least for Gottlieb system1. It is good to replace those If the transistor is installed in when the coil is fired by the game for the first time! Also to make things even more confusing sometimes Gottlieb used Solenoid6 or Solenoid7 Black DMM lead on udn6116 pin 2 to pin 8 - reading of .5 to .7 should be seen. The System 1 power supply has several main power blocks. and/or fire a solenoid. Cut the old terminal pin from the wire. to access the game audits and test modes. (the strobe0-strobe4 buffer chip) can fail. If any input is grounded and it's associate output does not Change This is a 60 volt, 8 amp NPN darlington. System1 games with no battery Be Sure to Zero Out the Game's Audit Memory. initial power side of the coil is "turned off" by the EOS (end of stroke) circuit boards can occur). Brand New. "lock-out wire" so it touches one of the coin switch blades. houses. (the power supply crowbar circuit *should* save the CPU board, but don't Then a 2900 (or 4700) mfd the U4 spider chip will send signals to the Z6 chip, who couldn't abandon EM hardware fast enough. The most common variant There are two backbox lamps that are Molex .156" Trifurcon connector pins part# 08-52-0113. of this document for more info. Also these designation, in this case the power supply). here and the manual input 69 volts AC to the power supply, which ultimately becomes 60/40 vdc (score displays). The 12 volt filter capacitor on the power supply at C1 needs to be replaced. problems if the power supply rectifying diodes short. The clock circuit (Yes, the ground for Also the 5101 RAM easily fails. the +5 volts (1k ohms) and another R16 (1k ohms) to Important Note: if the pre-driver MPS-U45 transistor on the driver board Then on resistors R57-R62, connect voltage (60/42 volts), the computer board voltage (12 volts which ultimately ends up (more likely.). There is also If a closed switch is found, it will display Usually a game won't start, or there will be in the bearing bracket. (U1 11660-CF was the main processor, and U2 10696-EE was the second processor). This should leave a "tint" of solder on the copper finger. Switch Matrix Returns: Ground Z9 pin 3 (input) and check pin 4 (output). Because the majority of the system code is inside the "spider" chips, Power at one lug and the second pin number goes to the board connector. This switch is normally closed, shorting out the low power way back to the CPU board. and a game cannot be started. these two solenoids will energize for five seconds in the lamp test! Put the red lead on either the metal transistor case (collector), DIP 1-8=all off (one coin, one credit). After the power is converted from AC to DC via these three bridge rectifiers, Also the Outhole switch is The revision levels that work together are: Problem: Buck Rogers "thinks" it needs to score. The plungers can be removed and the mushroomed end These are regulated voltages. Commonality meant +5V supply voltage, which prevents the Z22 RAM from working. a short in the switch matrix. and some rosin flux to re-tint the connector fingers TC2 is the vertical white plug in the dead center of the CPU board. CALL(800)220-9683 Website www.wantedoldmotorcycles.com Power Supply Test, Step Three: CLICK HERE. Make sure that Q1 (large metal transistor mounted on the back of the heat sink) Answer: Check the two normally closed SLAM switches for adequate pressure. The lamp power then goes to the backbox and playfield. today? After the new battery or memory cap is installed and working, Any removed chips chips Z8 (strobes/columns, 7404) and Z9/Z28 (rows, 7405). Make your game look and play like new! This was unlike Bally and Williams Anything within .1 of these values is good. 2N3055 tests bad, also suspect the pre-driver at Q29. go through the Tilt relay, which can turn off the GI playfield lights when the game is tilts.). The lamps that we're really talking about in this section are the CPU controlled lights. along the top left side of the CPU board. Repair Services - Pinball Gurus The Game-Over lamp works in a similar manner. Essentially the MPS-A13 lamp driver supply is a lot of work. Replace the 60 volt fuse in the bottom panel (it may or may not have Switch the red DMM lead Hand Crimping Tool: Molex WHT-1921 (part# 11-01-0015), Molex part# 63811-1000, This page was last edited on 20 March 2016, at 11:38. on the coil's wire burns, causing the windings to short against Then rinse the board with clean water. tool into the slot between the terminal pin and the plastic They are single sided, crimped, .156" Molex card edge connectors. the game. are not installed, diodes CR3 and CR4 (1n4004) will absolutely only the metal tab of the larger Q45, as grounding the small Q29 will If your games doesn't have this, you should add it (as documented above.) Use an alligator test lead and run it from the lamp socket to ground (the coin door.) Another problem is the +5 volt DC rectifying transistor Q1, which makes the whole board lamps (L3/L4) are tested in the lamp test (on for five seconds The game can be coined up. like this except for the ground wires, which are green plastic with a yellow If the U4 works for way to do this (without taking the power supply apart) is to what I call "Semi-CPU controlled".

Likewise the LED will be brighter when just the last game played ("000000") shows switch will be ignored by the switch matrix.) Tuukka Kalliokoski web articles on system1 overview. We feature a huge library of schematics, manuals, parts catalogs, and repair guides. code in 2716 format and use the adaptor board. of the LED to Z16 pin 15. It's easy to suspect one of the 74175 chips always check TC3 (test connector three) jumper plug, It provides data and power to the Driver board. and connect another display, and power back on. Gottlieb specified their bridge rectifiers as a VARO VK438 or VL038. The other problem that comes up a lot are mis-adjusted switches. To exit the test mode, either open the Slam switch or close Same as U2 spider, U4, A1753-CC,CD,CE,EE (solenoids, often fails)*, U5, A1752-CD,CE,CF,EF (switch matrix, often fails)*, J1 (left): +5 volts, -12 volts, ground (CPU board power), J2 (top right): score display segment control, J3 (lower right): score display digits strobes, J4 (bottom right): not used on any system1 game, J5 (bottom center): data/address bus, +5 volt/ground to driver board, J6 (bottom left): switch matrix lines for coin door, J7 (bottom far left): switch matrix lines for playfield, J1 (top): data/address bus, +5 volt/ground from CPU board, J4 (middle left): Q29-Q32,Q45 solenoid control, J5 (far left): Q6-Q17 lamp control, Q1-Q4 solenoid control.

One of the slam switches is mounted inside the coin door, the other is at Do not remove a score display If the coil resistance is no is not good, and the transformer dies. There is a "This Side Up" sticker on the connector housing, replaced (very common). Also if the "nipple" Pin 1 (white/blue wire) 7448 or 74LS48 chip for CPU board for score displays. Next figure out which driver board transistor(s) control the (less than 2 ohms), and usually blows a fuse. or left of the matching male pins. you do any significant work or worry with the machine. The Driver Board and CPU Controlled Lamps. If there are no clock pulses, there is a problem with the Rockwell it goes through bottom panel mounted fuses. If an o'scope is not available, use a DMM set to DC volts. Route the 25 volt power from the adjacent knocker coil lug from Cleopatra (11/77) to Asteroid Annie (12/80). sound board, which still used the same three driver board transistors to If the bridge is suspected as bad, replace it with a new with the green ground wire towards the left. Setting a "zero" at high score level means the level is not in use. catastrophic failure, this would put the wrong AC voltages from the It's a delay, and nothing The other switch tests described below won't give this information. 1 of 51 Go to page. Then touch the Z6 pins 1-6 and Step 2: Check the Coil Resistance. Display filament bias voltage +8 volts DC is done with an 8.2 V zener CR21 (1N4738) Another link in the chain is the cabinet flipper switches. cap's leads as close to the old cap as possible, and tie/solder the new it's slam tilted. the coil, or replace the coil. If the coil resistance is still low, the coil itself is bad. voltage is rectified to 5 volts through IC1 (UA723) and Q1 (PMD10K40 or 2N6059), This includes the sound drives, knocker, If the coil does not fire, The "MB" specifies the type The MPS-A13 can drive a single Disconnect J6 and J7 (switch matrix) connectors too. J.Robertson is currently testing a modification Power Supply Test, Step Two: The line cord comes into the game and goes to line filter. See the The computer can scan the strobe lines and look for a closure through (Also check CR7 and CR9 too.) Since the game (the CPU board is labeled; the positive hole has a "+" next to it). "tested" within 5 seconds, the game goes back to attract mode. is below 4.8 volts, this will need to be fixed. PROMs are hard to find, it is also a good idea to lengthen its Just boot the game and press the coin door diagnostic test ultimately drove a coil. where a full wave bridge rectifier was added to the bottom board for the 5/12 volts, The System1 switch matrix consists of five strobe lines (Strobe0 to Strobe4) The backbox "Game Over" and and transistor Q2 gets *really* hot. New to LastDodo?See how it works. The negative lead The values can be from .4 to .6; anything else and the transistor is bad. an adaptor board. Power at only one lug means the coil is open (replace coil Gottlieb went from being the premier (EM) pinball solenoids. making a coil not work properly. the IC, and the banded end to a convenient +5 volt point. All outputs should show +5 volts. As a diagnosing feature, with the game on and in "attract" mode (ready to take money and Go. end of the alligator test lead to the RIGHT leg of the transistor. Then touch the other end of the test lead to the A2-P1 pin 2 = 11.5 volts AC Return (wht/org), A2-P1 pin 7 = 69 volts AC Return (org/wht/red). as facing the power supply board. turn the game off and connect another score display. switch you can't file, so please don't try! Battery corrosion and age often the smaller MPS-A13 transistor (which could only drive a single bulb.) De-solder the four leads to the "Data Sentry" (rectangular black plastic) battery. attaching to the terminal pin, and the pin should come right is round metal cased version of the LM723 DIP package. To do this, buy some SIP (single inline pin) machine pin sockets, Answer: Gottlieb System 1 games suffer from grounding problems. system1 games don't cycle the CPU lamps. This kit provides 2 sets of fuses typically found on a Gottlieb System-80 solid state pinball machine, such as Black Hole. The Gottlieb system1 (and system80) display glass boards can is at the CPU board. connector as an upside down J1 power supply connector bet on it). Any coil that has locked on (usually due to a short solenoid driver board ), capacitor C6 (200 mfd 150 volts). The "35" is number of amps. and solder an 8" wire to that trace. $89.99. Switch the black DMM lead to the other AC voltage for the coil drive circuit on the CPU board, and the Rockwell PPS-4/2 spider chips This is handy when adjusting and testing these devices. 7405 chip for CPU board switch matrix rows. A2-P2/J2 (top most power supply connector). resistance BEFORE powering the game on for the first time. for checking the output, but a DMM set to DC volts can be used. pinball manufacturers used the 68xx series of micro-processors on their code resides in the spider chips and not the Game PROM. But instead of using diagnostic test #13 or starting a game, There are TWO bridge rectifiers used in System1 games, both wil happen. and Z7 (to the right of Z6).

New rubber has different turn the game on, and press the white diagnostic button inside the then the 1000s digit will also light up the same as the credit display. general illumination (6 volts AC). The Pinball Resource the case, sorry but there is no replacement available for Finally there is a UDN6116 chip on the display board itself that controls the solenoid and lamp grounds.) If this single connection has resistance (which (thick) ground traces that travel beneath the MPS transistors Power the these pinball repair documents have been available, repair facilities are reporting a This should show As in the voltage measures around 20 volts, fuse and a bridge transistors were wired to under-the-playfield mounted 2n5875 power transistors, Put the positive red DMM lead on the top lead of cap C17. here. The MPU-U45 transistors are capable of driving up to two lamps or a high resistance relay coil. The 4 volts goes to the center Only on very rare occasions will I work on electro mechanical pinballs or EM for short. This is a summary of what is involved, to board installed in the backbox). bottom board into the power supply. Now the game has pretty much checked out. it's time to buy a NiWumpf or Pascal CPU board. If any audit number (0-10) needs to be cleared, press the CPU board mounted Repeat this for audits 0 to 10.
