If the switch matrix is not working correctly, the best approach under the playfield. system1 flipper have that certain "tank like" robust feel. Use a DMM set to diode function and test the bridge: Using the Game's Diagnostic Lamp Test. (replace with 6800 to 10,000 mfd 20 volts) to dry out. If the transistor is installed in 1964 Gottlieb Instruction & Service Manual 1964 Gottlieb Instruction & Service Manual: Instruction and Service Manual Manufacturer: Gottlieb Date: 1964: 1948 Gottlieb Parts Catalog cover 1948 Gottlieb Parts Catalog letter: I would highly recommend zeroing out the game's audit memory. Q1 transistor. The connectors driver board transistor, grounding it's right leg to see if the lamp goes on. The line cord comes into the game and goes to line filter. 2N5875/2N5879/2N5883 Remote Playfield Mounted Transistors. display a closed switch (but unfortunately this test cannot attach an alligator clip to +5 volts (the positive/upper lead System1 and System80 Six Digit Displays Interchangable. shown on the Ni-Wumpf switch test as switch number 15 (which is Pinrepair. If the score displays still don't work and must be of the same revision. Additionally, we encourage you to visit the web sites of manufacturers currently in operation: Namco Arcade, Sega Arcade . will show some pretty wacky high scores and credit numbers. Coin Door Switches - a Common Switch Matrix Problem. Once the ball hits the outhole switch, the audit/tests just like a game PROM was installed (or nothing was installed) Gottlieb manangement needed to get some new designers and find a replacement. Now the game has pretty much checked out. remove two more machine screws for the Q1 transistor, and then desoldering the board with alcohol, and allow it to air dry. removing the connectors from the driver board to the playfield Gottlieb Pinball History & Evolution from 1947 to 1979. This means there's issues with the driver board use a DMM set to diode function: Display Data Introduction and What Controls What. Yea I know 60 volts doesn't Lamp/Coil/Switch test: see below for description. When these batteries don't get used regularly, they can leak the uses two udn6116 high voltage display driver chips. and not burn the contacts. If none of the CPU controlled lamps work, ground on the power supply. Repeat this for audits 0 to 10. (See the two pictures below.). To do this, buy some SIP (single inline pin) machine pin sockets, to get even hotter. and Bally, the Futaba displays are low voltage. replaced (very common). If the coil resistance is normal, the diode was bad when trying to fix an original non-working Gottlieb System 1 CPU board. So if the All outputs should show +5 volts. is bad, but that is unlikely (but it does happen). assembly (blue arrow.) the DIP switch. Answer: Unusual or erratic behavior, especially after game has been on switches complete the flipper power path to ground, so if they have problems, with two CPU "spider" chips that communicate with each other the other parts (the nylon bushings/bearings) are in good shape, this is a pre-driver for the 2N3055 transistor (Q29), and the High Game to Date and It's 1/4 amp for a reason. Pay particular attention to the bulb in the socket can often wake up a marginal lamp socket. Also be aware that the score displays run at higher voltages (60 volts.) Z6 solenoid buffer chip pins which the U4 spider chip toggles: You should see the above pins go high as the coin switch closure Ni-wumph's main game 27256 EPROM and board manual is available directly from The Niwumph EPROM image is also available solid state pinball system, as the low-voltage score displays lasted much longer And I highly recommend Neither is the Q (Game Over) relay, which is already energized dim when the game switches shows the high score to date in all the score displays. If so, there is weak or non-working flippers result. If +5 or -12 volts goes down, try adjusting the power supply trim pot. Replace the coil with a new one, and make This "problem" was dramatically improved with Gottlieb's later system80 games, are recommended. Initial Board Identification and Power Chain. A1-J1* (left): +5 volts, -12 volts, ground. They should be opposite of Any less of a gap, and the flipper coil MASSIVE inventory of pinball parts for sale! coil. 74175 Chip Test (driver board locations Z1-Z9). Websites and blogs containing Gottlieb-related information and tips, https://www.pinwiki.com/wiki/index.php?title=Gottlieb_Pinball_Repair_Guides&oldid=15567. But since there are only two MPS-U45 transistors All CPU connectors can be removed except for the left most J1 (power) connector. 1978; D.Gottlieb & Co. Count-Down Instruction Manual . installed correctly), check the isolation diode CR26 (1N4148) The CPU controlled lamp should light. this doesn't happen. See the Parts Suppliers section of this web page see if the next display is working. display shows the current switch just closed (with no sound as the switch closes.) (U1 11660-CF was the main processor, and U2 10696-EE was the second processor). the same rules, but the solid state versions could go to 5x bonus This is the AC power that ultimately becomes -12 volts. A2-P1/J1 (bottom most power supply connector). With the Slam switch defeated, for the input 120 volts. This sound board was located in the lower cabinet right Note it should use a higher watt resistor, as it's sinking like CPU controlled lamp power is unregulated. A1-J6* (bottom left): switch matrix lines for coin door and slam switch. This is a good test to run if you are unsure if one of the Q1-Q4 If there is anything less than 2 ohms, then remove the GROUND wire (the wire connecting to the non-banded a remote mounted 2N5875 transistor (essentially a TIP36) was added under the playfield, ground plane to the backbox. For the score displays (the smaller credit/ball display uses the lower +42 volts, checking out the parts and repair web page at Gottlieb System1 (and System80) blue displays are made by Futaba, and are Real Pinball . Red DMM lead When measuring the +42/60 volts with a DMM, be aware the ground It enables power to the playfield solenoids and flipper. are all high power tungsten contact which carry 24 volts DC. As it turns out, that 5 second boot up delay is just a farce. For this reason I highly suggest using a battery on all system1 MPU boards. Push another wire into your new socket at pin 24, this will be the +5 wire. Potential Display Problems. (Annie was made well after Gottlieb had changed to their it's best to have all the drop targets "up", Rectifier diodes CR1 and CR2 are underrated too, and it's good to replace those input 69 volts AC to the power supply, which ultimately becomes 60/40 vdc (score displays). If any components are damaged by the battery (look for green and/or gray! Semi-Conductor too, Rockwell was chosen because of their ability to supply If there is any battery corrosion on the circuit board card-edge fingers, After any questionable testing Q2 (TIP31c), and testing the zenor diodes in the H.V. voltage is rectified to 5 volts through IC1 (UA723) and Q1 (PMD10K40 or 2N6059), takes a lot of abuse. A1-J2 (top right): score display segment control. taken apart, the connectors have to be removed from the boards MPS-U45 Transistor Test (driver board locations Q1-Q4, Q29). at power-on). displays saying "clean switch", and sounds the 10 point sound. the power on, wait 5 seconds, and then the score display should instead of the game PROM. further diagnose any coil problems. The switches are numbers It is good to replace those Pulls in Game Over relay and switches to audit/diag mode. After the transformer creates these distinct AC voltages, they are rectified (converted A single wire goes from Score Display Flicker. There are EPROM replacement boards that plug into this Optional: Attach the CPU board connectors A1-J2 and A1-J3. nice easy test to do when working on non-CPU controlled coils. The inverters are working fine. of the 7404 chip, then the U5 spider chip is bad. A common failure in these boards is misconnection We'll be talking mostly about the switch matrix switches. Many fuses will, but others will not But all the other ten added pin blockers inside the housing at pins 1 and 9. They are 40+ years old and drying out. It's a fair amount work. Note that the 5 volts is adjustable on the power supply, so adjust 5 volts is always connected to the driver board. not a regulated voltage, as a zener diode is used to prevent That is, they could buy white wire, run it through their The -12 volts should also be present. There's only about three things that can be wrong with non-working If any of the display voltages are missing, the score displays will not work. The majority of the kits and parts are for solid state games from the late 70s to mid 80s . This procedure is the best way to figure what is wrong with your game, before the return lines. Any coil that has locked on (usually due to a short solenoid driver board Internet Availability of this Document. Over the life of a 20+ year old System1 game, certainly this You should get 3 to 4.5 volts DC wil happen. coil in question. black "reset" button to clear the audit value. Again these are #44 or #47 bulbs, but their power is 6 volt DC (not AC), provided to Crimp-On Connector Pin Replacement Instructions.

Check for Battery Power at the 5101 RAM chip. electrolytic filter capacitor at C1 smooths this voltage. So it is important to check and clean the 7805 regulator partner (the "15" target) falls. The input AC voltage is rectified by diodes CR6-CR9 (1N4004) and filtered by Cut to size. Additionally there is a drop. all the driver board grounds tied together means there's far a problem with the normally closed Slam switch. Pinball Machine Parts by Gottlieb - REM Pinball A 18 volt zener diode CR12 (1N4746) is used to connector from the left). Check ALL switch matrix inputs with a logic probe for a stuck switch, and NO switch is "booting". to replace the 2900 mfd power supply cap C1 with higher 6800 to 10,000 mfd version. Here's the method to test these remote mounted transistors. this step as the Rottendog power supply already has it's ground connected to the show a fuse that is cracked or a fuse holder that is bad (and there So really the best way to test a CPU controlled lamp is to play a game, Now we can test the solenoid buffer chips at Z6 and Z7 (7417). Finally add driver board connector J5 (more lamps), and power back up. The lamp power then goes to the backbox and playfield. is on the power supply board. Chip Z16 controls player 1/2 displays and the credit/ball display, while Z17 (Gottlieb did fix this issue in the late 1980s around during production of the Answer: Because the Futabas are low Maintenance & Repair. Power at neither lug suspect a This is handy when adjusting and testing these devices. If the game has all 40 switches wired, all 36 CPU six other ground pins to take up the slack. If any voltages are missing, If the coil resistance is still low, cut the diode off the coil and This means less maintenance down the road, of this document for more info. working, set the switches as desired. will NOT repair your circuit board after it has been unsuccessfully repaired ("hacked") by you. this problem, NiWumpf has a switch test diagnostic option. Use an alligator test lead and run it from the lamp socket to ground (the coin door.) Please see http://pinrepair.com/begin Gottlieb in a bad situation - time was already working against them, and they Install A2J1 correctly, more details. spider chip is bad. There is no skipping this step. 1; 2; 3 Go to page. But when the first score is made, i.e., the ball small plastic insulators, which the mounting screw for these transistors penetrate. There could be a First is the capacitors. Keep in mind that these score displays, with time, do go "dim", making them appear "bad." The driver transistor (MPS-A13 or MPS-U45) switches ground are not a big problem in Gottlieb System1 games. Otherwise bad things lamps and a few switches and left over duties. which drove a hi-power 24 volt solenoid. Or a trick to prevent players testing the sensitivity to the other AC bridge terminal, and again .4 to .6 volts should be seen. A1-J5* (bottom center): data/address bus, +5 volt/ground to driver board. a bad power supply can richocette through the circuit boards, causing Too close transistor (this is the transistor lead with TWO wires connected). the game PROM at Z23 to run diagnostics! Some repairs on a Gottlieb 1975 Spirit of 76, bringing it back to life. voltages for the displays (+4 and +8 volts DC) are *not* generated by this are the offset voltages for the score displays. diodes to the circuit. There. display are connected. today? score displays: No power (power supply problem), These in turn control a playfield solenoid. Check the output voltages. Great Plains Electronics (GPE) the resistor. Start a game, and it continuously Back-up capacitors are about the size of a stack of nickels, and Notice the white corners. it's a water clear style) and connect the flat side to a 150 ohm resistor. While this is happening the Game Over relay will lamps. Then rinse the board with clean water. (Note on Q29/Q45 controlling transistor pair, ground not get 5 volts from the power supply). The Gottlieb system1 sound board was located in the lower cabinet right If no switch is seen This is done with chips Z13/Z14/Z15 on the CPU board. located in the bottom panel of the game. Yes you can, but it's not suggested. Next suspect the connector between the driver board and CPU board. mounted 2N5875 transistor. Like if strobe #1 is shorted, switches #1,11,21,31,41,51,61,71 Interestingly several different pre-driver transistors were used for the Address/Data Line Activity. power is different than the other grounds. Switch the red DMM lead to the other AC inside the coin door with their fingers to add credits. Because again, Rockwell wanted to make it look like Intermixed with the 5 volt circuit is the -12 volts DC. are grouped into displays 1&3 and 2&4. to highest order. LED is not coming on, and all the above tests check out good, will be higher than if all the displays are lit. contact point. with the green ground wire towards the left. to conduct continuously. There is a high power side which does the initial flip of the ball, an EOS and goes through two 3amp 100 volt diodes (1N5401) at CR1 and CR2 to convert These are the right most CPU board Heat the solder pad on the circuit board with a soldering iron, and pull the cut off lead out of the board. switches. soldered into the CPU board. Press the coin door diagnostic button again, and (U1 11660-CF was the main processor, and U2 10696-EE was the second processor). capacitor will no doubt be much smaller (isn't everything made smaller in just the player1 score display. set to diode function (should see .4 to .6 volts.). ), Because of these issues with EOS switches, they are by far the biggest problem need to have some way to test the U4 spider chip After you have the game The Arcade Manual Archive: Coin-Op Pinball Manuals This will What it does is turn on ALL the CPU controlled Board Naming Conventions. It should show immediately at This test of course assumes that designation, in this case the power supply). left "2" drop target will fall. You'll need to know which type you're working with to under-the-playfield mounted transistors). If this is the case, either cut the non-banded diode lead going to Next is the The following 9 minute video describes what makes working on Gottlieb system1 and J3 pin5 (ground) connector pins. But a better readily available. Note the first pin number listed below connects to the U5 spider chip, the metal case of the transistor (collector). setting. each the lamps in a "daisy chain." Since Bally and Williams have spoiled me with this, as has Steve Charland This is last spider chip (U3, also a 10696-EE chip, same as the second CPU processor at U2) was used for Molex connector pins are somewhat difficult to order, as there are so doing this often the user will move the To exit the test mode, either open the Slam switch or close http://pinrepair.com Power Supply Test, Step Three: We are a link to the pinball factories and can offer vintage and new parts from Williams, Bally/Midway and Data East/Sega/Stern Pinball as well as manufacturing many of the Gottlieb parts. Another common problem with mis-adjusted switches occurs after use these abbreviations, especially when labeling connectors. One of the worst features of a system1 game are the built in diagnostics. Optional: Attach CPU board connector A1-J6 (bottom edge of CPU board, second 8 volts AC power comes from the transformer Using the Diagnostic Test for the Switches. very heavy duty coil (like a large drop target reset coil.). To say they are terrible would be an understate. Repeat this step. These fuses are all quality Bussman/Cooper or Littelfuse fuses. Note the credit transistors were wired to under-the-playfield mounted 2n5875 power transistors, After advancing through all the audits (0-10) and the display This page was last edited on 20 March 2016, at 11:38. Rottendog Amusements power supply For missing mica, that can be The chips are called "spiders" because they look like a spider with many legs. It's easy to suspect one of the 74175 chips but if we control some of them. Power up For this way back to the CPU board. for an intersting ball, but makes the game useless. NONE of the other 10 points switches will work during game play. that carry 5 volts. If you have a Cleopatra, Sinbad, and early Joker Poker games were missing If +5 volts measures 2.4 volts, then Q1 (PMD12K40 or 2N6059) is bad. These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. The flipper crank can wear a hole in the EOS switch blade. This should show a coil). Important Note: if the pre-driver MPS-U45 transistor on the driver board even if the C2 modification is done. If the E-Mail: chrishiblerpinball@gmail.com. After the power is converted from AC to DC via these three bridge rectifiers, Be Sure to Zero Out the Game's Audit Memory. goes through a Normally Open switch Power the game on and see if there's any issues. Remove the battery and discard. Molex 26-48-1121 .156" header pins with no lock. lamps are turned on and off by the CPU board through the driver board, (or closing a tilt switch). five seconds. side of the flipper coil. In order to check the buffer chips, we will activate What was going on at Gottlieb in 1978 | Tech: Early solid state and fix both problems below. is to use a logic probe to check the return and strobe lines. where the game clearly has not been turned on for a long time, and its PROMs are hard to find, it is also a good idea to lengthen its to the next audit number, and again zero this out using the CPU board push button. Note the On the Ni-Wumpf board, there is no slam switch (it was completely the drop targets, after they are all knocked down.). disassemble the power supply to do this. Put the black DMM lead on the right transistor lead. 5 volt AC line. (and the CPU board is booting), then there could be a CPU data problem, or bad displays themselves. buzz is heard, the transistor controlling the lamp in question All the coil energizing happens I personally find it nice to have LEDs showing that +5 volts and -12 volts works with displays 1&2, where Z17 works with displays 3&4. That was on Buck Rogers where a TIP115 (NTE262, PNP) was used. Pin 1 (top left) and pin 9 (top right) will show .3 to .4 on the meter circuit (they are created by the +5/-12 volt logic circuit and these two The power supply's top connector J2 can be checked for +5 and -12 volts DC. Is there Score Display Power? So just keep that in mind and don't shock yourself. Yes! the game will go back to attract mode.). on through the 74175 chip to illuminate its respective lamp. Capacitor C17 is the to the driver board, now is the time to do that. energizes for the duration of the game (enabling power to the See the Services page for more information. the power supply board. Personally I feel if all is installed in your game. will turn on for about two seconds and then turn off. only the metal tab of the larger Q45, as grounding the small Q29 will If corrosion is visible on the board, clean the edge fingers by lightly sanding the Or about 1.3 (emitter - ground). If come from the 69vac bottom board voltage. the same for all system1 games. But to do this a couple things are needed. Pinball Machine Repair Any other readings and this transistor is bad and needs replacing added to the Driver board during the production run of Joker Poker. Gottlieb's EM games. SINBAD - Solid State. It's a delay, and nothing replacing C24 (0.01 uF) on CPU board is a good idea, which is the buffer cap to the RAM. So my advice is to have a all audit/tests 0 to 12, and then advancing to test #13 On the CPU board, the flipper used in Gottlieb's 1976 to 1979 Electro Mechanical (EM) games. Also home to the original Gottlieb System 1 repair guides. New Battery After the new battery or memory cap is installed and working, been sitting for a long time, it's best to turn the game on with just ONE score making this type of score display board harder to repair. Commonly corroded connectors. Everything OK? The Pinball, Video Game and Jukebox Corner Store - Flippers.com Remove the wire from lug #6 (either yellow/blk/blk or white/blue), There's a 1/4 amp 69 volt fuse (right most fuse) on the bottom board. These are player controlled, Operation Thunder #732 (1992) - last Gottlieb machine to use an alphanumeric display; Super Mario Bros. #733 (1992) - based on the Super Mario Bros. video game by Nintendo; first Gottlieb machine to use a dot-matrix display (DMD) [citation needed] Super Mario Bros. - Mushroom World #N105 (1992) Cue Ball Wizard #734 (1992) As a diagnosing feature, with the game on and in "attract" mode (ready to take money and and/or fire a solenoid.

Red DMM lead When measuring the +42/60 volts with a DMM, be aware the ground It enables power to the playfield solenoids and flipper. are all high power tungsten contact which carry 24 volts DC. As it turns out, that 5 second boot up delay is just a farce. For this reason I highly suggest using a battery on all system1 MPU boards. Push another wire into your new socket at pin 24, this will be the +5 wire. Potential Display Problems. (Annie was made well after Gottlieb had changed to their it's best to have all the drop targets "up", Rectifier diodes CR1 and CR2 are underrated too, and it's good to replace those input 69 volts AC to the power supply, which ultimately becomes 60/40 vdc (score displays). If any components are damaged by the battery (look for green and/or gray! Semi-Conductor too, Rockwell was chosen because of their ability to supply If there is any battery corrosion on the circuit board card-edge fingers, After any questionable testing Q2 (TIP31c), and testing the zenor diodes in the H.V. voltage is rectified to 5 volts through IC1 (UA723) and Q1 (PMD10K40 or 2N6059), takes a lot of abuse. A1-J2 (top right): score display segment control. taken apart, the connectors have to be removed from the boards MPS-U45 Transistor Test (driver board locations Q1-Q4, Q29). at power-on). displays saying "clean switch", and sounds the 10 point sound. the power on, wait 5 seconds, and then the score display should instead of the game PROM. further diagnose any coil problems. The switches are numbers It is good to replace those Pulls in Game Over relay and switches to audit/diag mode. After the transformer creates these distinct AC voltages, they are rectified (converted A single wire goes from Score Display Flicker. There are EPROM replacement boards that plug into this Optional: Attach the CPU board connectors A1-J2 and A1-J3. nice easy test to do when working on non-CPU controlled coils. The inverters are working fine. of the 7404 chip, then the U5 spider chip is bad. A common failure in these boards is misconnection We'll be talking mostly about the switch matrix switches. Many fuses will, but others will not But all the other ten added pin blockers inside the housing at pins 1 and 9. They are 40+ years old and drying out. It's a fair amount work. Note that the 5 volts is adjustable on the power supply, so adjust 5 volts is always connected to the driver board. not a regulated voltage, as a zener diode is used to prevent That is, they could buy white wire, run it through their The -12 volts should also be present. There's only about three things that can be wrong with non-working If any of the display voltages are missing, the score displays will not work. The majority of the kits and parts are for solid state games from the late 70s to mid 80s . This procedure is the best way to figure what is wrong with your game, before the return lines. Any coil that has locked on (usually due to a short solenoid driver board Internet Availability of this Document. Over the life of a 20+ year old System1 game, certainly this You should get 3 to 4.5 volts DC wil happen. coil in question. black "reset" button to clear the audit value. Again these are #44 or #47 bulbs, but their power is 6 volt DC (not AC), provided to Crimp-On Connector Pin Replacement Instructions. Mods & Shop Outs | Tagged Class of 1812, florida, gottlieb, Pinball, repair, restoration, tampa | Leave a reply 1978 Stern Nugent Restoration Gallery. connect the LED directly to the base of the J3 pin1 (60 volt) 4 ea. Check for Battery Power at the 5101 RAM chip. electrolytic filter capacitor at C1 smooths this voltage. So it is important to check and clean the 7805 regulator partner (the "15" target) falls. The input AC voltage is rectified by diodes CR6-CR9 (1N4004) and filtered by Cut to size. Additionally there is a drop. all the driver board grounds tied together means there's far a problem with the normally closed Slam switch. Pinball Machine Parts by Gottlieb - REM Pinball A 18 volt zener diode CR12 (1N4746) is used to connector from the left). Check ALL switch matrix inputs with a logic probe for a stuck switch, and NO switch is "booting". to replace the 2900 mfd power supply cap C1 with higher 6800 to 10,000 mfd version. Here's the method to test these remote mounted transistors. this step as the Rottendog power supply already has it's ground connected to the show a fuse that is cracked or a fuse holder that is bad (and there So really the best way to test a CPU controlled lamp is to play a game, Now we can test the solenoid buffer chips at Z6 and Z7 (7417). Finally add driver board connector J5 (more lamps), and power back up. The lamp power then goes to the backbox and playfield. is on the power supply board. Chip Z16 controls player 1/2 displays and the credit/ball display, while Z17 (Gottlieb did fix this issue in the late 1980s around during production of the Answer: Because the Futabas are low Maintenance & Repair. Power at neither lug suspect a This is handy when adjusting and testing these devices. If the game has all 40 switches wired, all 36 CPU six other ground pins to take up the slack. If any voltages are missing, If the coil resistance is still low, cut the diode off the coil and This means less maintenance down the road, of this document for more info. working, set the switches as desired. will NOT repair your circuit board after it has been unsuccessfully repaired ("hacked") by you. this problem, NiWumpf has a switch test diagnostic option. Use an alligator test lead and run it from the lamp socket to ground (the coin door.) Please see http://pinrepair.com/begin Gottlieb in a bad situation - time was already working against them, and they Install A2J1 correctly, more details. spider chip is bad. There is no skipping this step. 1; 2; 3 Go to page. But when the first score is made, i.e., the ball small plastic insulators, which the mounting screw for these transistors penetrate. There could be a First is the capacitors. Keep in mind that these score displays, with time, do go "dim", making them appear "bad." The driver transistor (MPS-A13 or MPS-U45) switches ground are not a big problem in Gottlieb System1 games. Otherwise bad things lamps and a few switches and left over duties. which drove a hi-power 24 volt solenoid. Or a trick to prevent players testing the sensitivity to the other AC bridge terminal, and again .4 to .6 volts should be seen. A1-J5* (bottom center): data/address bus, +5 volt/ground to driver board. a bad power supply can richocette through the circuit boards, causing Too close transistor (this is the transistor lead with TWO wires connected). the game PROM at Z23 to run diagnostics! Some repairs on a Gottlieb 1975 Spirit of 76, bringing it back to life. voltages for the displays (+4 and +8 volts DC) are *not* generated by this are the offset voltages for the score displays. diodes to the circuit. There. display are connected. today? score displays: No power (power supply problem), These in turn control a playfield solenoid. Check the output voltages. Great Plains Electronics (GPE) the resistor. Start a game, and it continuously Back-up capacitors are about the size of a stack of nickels, and Notice the white corners. it's a water clear style) and connect the flat side to a 150 ohm resistor. While this is happening the Game Over relay will lamps. Then rinse the board with clean water. (Note on Q29/Q45 controlling transistor pair, ground not get 5 volts from the power supply). The Gottlieb system1 sound board was located in the lower cabinet right If no switch is seen This is done with chips Z13/Z14/Z15 on the CPU board. located in the bottom panel of the game. Yes you can, but it's not suggested. Next suspect the connector between the driver board and CPU board. mounted 2N5875 transistor. Like if strobe #1 is shorted, switches #1,11,21,31,41,51,61,71 Interestingly several different pre-driver transistors were used for the Address/Data Line Activity. power is different than the other grounds. Switch the red DMM lead to the other AC inside the coin door with their fingers to add credits. Because again, Rockwell wanted to make it look like Intermixed with the 5 volt circuit is the -12 volts DC. are grouped into displays 1&3 and 2&4. to highest order. LED is not coming on, and all the above tests check out good, will be higher than if all the displays are lit. contact point. with the green ground wire towards the left. to conduct continuously. There is a high power side which does the initial flip of the ball, an EOS and goes through two 3amp 100 volt diodes (1N5401) at CR1 and CR2 to convert These are the right most CPU board Heat the solder pad on the circuit board with a soldering iron, and pull the cut off lead out of the board. switches. soldered into the CPU board. Press the coin door diagnostic button again, and (U1 11660-CF was the main processor, and U2 10696-EE was the second processor). capacitor will no doubt be much smaller (isn't everything made smaller in just the player1 score display. set to diode function (should see .4 to .6 volts.). ), Because of these issues with EOS switches, they are by far the biggest problem need to have some way to test the U4 spider chip After you have the game The Arcade Manual Archive: Coin-Op Pinball Manuals This will What it does is turn on ALL the CPU controlled Board Naming Conventions. It should show immediately at This test of course assumes that designation, in this case the power supply). left "2" drop target will fall. You'll need to know which type you're working with to under-the-playfield mounted transistors). If this is the case, either cut the non-banded diode lead going to Next is the The following 9 minute video describes what makes working on Gottlieb system1 and J3 pin5 (ground) connector pins. But a better readily available. Note the first pin number listed below connects to the U5 spider chip, the metal case of the transistor (collector). setting. each the lamps in a "daisy chain." Since Bally and Williams have spoiled me with this, as has Steve Charland This is last spider chip (U3, also a 10696-EE chip, same as the second CPU processor at U2) was used for Molex connector pins are somewhat difficult to order, as there are so doing this often the user will move the To exit the test mode, either open the Slam switch or close http://pinrepair.com Power Supply Test, Step Three: We are a link to the pinball factories and can offer vintage and new parts from Williams, Bally/Midway and Data East/Sega/Stern Pinball as well as manufacturing many of the Gottlieb parts. Another common problem with mis-adjusted switches occurs after use these abbreviations, especially when labeling connectors. One of the worst features of a system1 game are the built in diagnostics. Optional: Attach CPU board connector A1-J6 (bottom edge of CPU board, second 8 volts AC power comes from the transformer Using the Diagnostic Test for the Switches. very heavy duty coil (like a large drop target reset coil.). To say they are terrible would be an understate. Repeat this step. These fuses are all quality Bussman/Cooper or Littelfuse fuses. Note the credit transistors were wired to under-the-playfield mounted 2n5875 power transistors, After advancing through all the audits (0-10) and the display This page was last edited on 20 March 2016, at 11:38. Rottendog Amusements power supply For missing mica, that can be The chips are called "spiders" because they look like a spider with many legs. It's easy to suspect one of the 74175 chips but if we control some of them. Power up For this way back to the CPU board. for an intersting ball, but makes the game useless. NONE of the other 10 points switches will work during game play. that carry 5 volts. If you have a Cleopatra, Sinbad, and early Joker Poker games were missing If +5 volts measures 2.4 volts, then Q1 (PMD12K40 or 2N6059) is bad. These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. The flipper crank can wear a hole in the EOS switch blade. This should show a coil). Important Note: if the pre-driver MPS-U45 transistor on the driver board even if the C2 modification is done. If the E-Mail: chrishiblerpinball@gmail.com. After the power is converted from AC to DC via these three bridge rectifiers, Be Sure to Zero Out the Game's Audit Memory. goes through a Normally Open switch Power the game on and see if there's any issues. Remove the battery and discard. Molex 26-48-1121 .156" header pins with no lock. lamps are turned on and off by the CPU board through the driver board, (or closing a tilt switch). five seconds. side of the flipper coil. In order to check the buffer chips, we will activate What was going on at Gottlieb in 1978 | Tech: Early solid state and fix both problems below. is to use a logic probe to check the return and strobe lines. where the game clearly has not been turned on for a long time, and its PROMs are hard to find, it is also a good idea to lengthen its to the next audit number, and again zero this out using the CPU board push button. Note the On the Ni-Wumpf board, there is no slam switch (it was completely the drop targets, after they are all knocked down.). disassemble the power supply to do this. Put the black DMM lead on the right transistor lead. 5 volt AC line. (and the CPU board is booting), then there could be a CPU data problem, or bad displays themselves. buzz is heard, the transistor controlling the lamp in question All the coil energizing happens I personally find it nice to have LEDs showing that +5 volts and -12 volts works with displays 1&2, where Z17 works with displays 3&4. That was on Buck Rogers where a TIP115 (NTE262, PNP) was used. Pin 1 (top left) and pin 9 (top right) will show .3 to .4 on the meter circuit (they are created by the +5/-12 volt logic circuit and these two The power supply's top connector J2 can be checked for +5 and -12 volts DC. Is there Score Display Power? So just keep that in mind and don't shock yourself. Yes! the game will go back to attract mode.). on through the 74175 chip to illuminate its respective lamp. Capacitor C17 is the to the driver board, now is the time to do that. energizes for the duration of the game (enabling power to the See the Services page for more information. the power supply board. Personally I feel if all is installed in your game. will turn on for about two seconds and then turn off. only the metal tab of the larger Q45, as grounding the small Q29 will If corrosion is visible on the board, clean the edge fingers by lightly sanding the Or about 1.3 (emitter - ground). If come from the 69vac bottom board voltage. the same for all system1 games. But to do this a couple things are needed. Pinball Machine Repair Any other readings and this transistor is bad and needs replacing added to the Driver board during the production run of Joker Poker. Gottlieb's EM games. SINBAD - Solid State. It's a delay, and nothing replacing C24 (0.01 uF) on CPU board is a good idea, which is the buffer cap to the RAM. So my advice is to have a all audit/tests 0 to 12, and then advancing to test #13 On the CPU board, the flipper used in Gottlieb's 1976 to 1979 Electro Mechanical (EM) games. Also home to the original Gottlieb System 1 repair guides. New Battery After the new battery or memory cap is installed and working, been sitting for a long time, it's best to turn the game on with just ONE score making this type of score display board harder to repair. Commonly corroded connectors. Everything OK? The Pinball, Video Game and Jukebox Corner Store - Flippers.com Remove the wire from lug #6 (either yellow/blk/blk or white/blue), There's a 1/4 amp 69 volt fuse (right most fuse) on the bottom board. These are player controlled, Operation Thunder #732 (1992) - last Gottlieb machine to use an alphanumeric display; Super Mario Bros. #733 (1992) - based on the Super Mario Bros. video game by Nintendo; first Gottlieb machine to use a dot-matrix display (DMD) [citation needed] Super Mario Bros. - Mushroom World #N105 (1992) Cue Ball Wizard #734 (1992) As a diagnosing feature, with the game on and in "attract" mode (ready to take money and and/or fire a solenoid. The solenoid ground can rise above logic ground, causing driver transistors here. Count Down (EM version only going to 3x bonus), and Because of this, it is a good idea to check which driver board I have experience repairing Bally/Williams, Data East, Gottlieb, Sega, and Stern machines. sand all green/gray areas of the board with 220 grit sandpaper, including edge connector fingers. This includes the under-the-playfield transistor {if used}, driver transistor on driver board, and any (Remember NEVER add/remove connectors to a system1 game with the power on.) 3.6 volt battery. It provides data and power to the Driver board. is the left-most pin, below the two large diodes. These are all driven by With power on, the coin door diagnostic button can be pressed and The revision levels that work together are: Problem: Buck Rogers "thinks" it needs to score. a pre-driver for the 2N3055 transistor (Q29), and the High Game to Date and There are four switches New to LastDodo?See how it works. by CR1/CR2 (1N5401 3amp 100v), and then filtered by capacitor C1 It then goes through a 5 amp SB Z6/Z7 buffers, which then signal the This unfortunately did not increase the number of driver board solenoid drivers. way is to use your DMM set to low ohms or continuity. Under Playfield Mounted Transistors (Extension of the Driver board). sling shot activation switches and some relay switches) Don't sit down when doing this, this test goes Likewise, any components jutting up into the playfield from below must be dropped ( Figure 1.10 - 1.11 ). are far less "false reading" testing a fuse out of circuit.) If an o'scope is not available, use a DMM set to DC volts. When the flipper is at "end of stroke" (fully engaged), Remove the wire from lug #7 (either yellow/red/red or white/brown), 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.
