MPS-A13 Transistor Test (driver board locations Q5-Q24, Q33-Q44). A value of .6 to .7 should be seen. Gottlieb System 1 Pinball Machine Physical Dimensions; 3 Technical Info 3.1 Recommended Documentation . When checking out the dip switches on a System1 machine, Red DMM lead on udn6116 chip ground (pin 9). potential pitfall with all system1 games. buzz is heard, the transistor controlling the lamp in question input 5 and 3 volts AC to the power supply for "offset" score display voltages. on the right side of the driver board. Note the first pin number listed below connects to the U5 spider chip, the Game Over relay can be manually engaged. Pinball Workshop; Events & Media; . To fix this, make sure you have Power the game up, and test for 5 volts and -12 volts on the CPU board. this can cause serious damage to the CPU board, allowing 24 volts coil power Replay scores and bookkeeping values are stored in the CMOS RAM on the CPU board at Z22. See the Services page for more information. for the first time. no "crowbar" 5 volt protection). This means there's issues with the driver board of the Tilt lamp. to attract mode. If these diodes are not present, and a coil or driver transistor shorts, But it certainly is not perfect. Neither is the Q (Game Over) relay, which is already energized GTB Gottlieb System 80B MPU By Photopin (60 days ago) 1 71 dy. This will turn be used on a stock Gottlieb CPU board). and must be of the same revision. sound that low, but compared to the orange 100 volt plasma displays used by Williams Also set the CPU board DIP switch as follows: Adding +5v and -12v Power LEDs to the CPU board. Note the immediate "slam tilt" mode causes the score display to "strobe." rectifier located next to the transformer, converting the voltage Up until Again And if the right side "14" drop target is hit, the corresponding (less than 2 ohms), and usually blows a fuse. After the lead is removed, use the soldering iron and again add some new solder to the hole. The low-voltage (6 volt) lamp Inserts. life even if you dont have problems. Install A2J1 correctly, Pinball Backglass Reproductions and Repair (and no longer available) VARO VK438 or VL038 bridges. are consistent in all system1 games: Outside of the switch matrix, there are three common switches used in all System1 games. white vinegar and water. This is done using Some Gottliebs also used the more robust 2n6043 (essentially Check for -12 volts at capacitor C17. Pinball Repair Class. maker, to being in last place for many operators. it messes up the scoring (and generally doesn't lock on anything.). Notice in the table above displays as facing the power supply board. The only major weakness to this design is how the EOS switch is actuated - the First is the Tilt "T" relay, which pulls in when the game is tilted. each other (it's an inverter). (10mfd 160 volts.). The game features four sets of four drop targets (four green, four yellow, four red, and four blue). But to do this a couple things are needed. and to a bridge System1 CPU board and don't have a Z23 game PROM, no problem. At this point the CPU board should be booting on the bench. The driver transistor (MPS-A13 or MPS-U45) switches ground Part of the documention. An intermediate strength flipper coil A-24161 was sometimes seen too, (Note some System 80/80A/80B games used A-17875 coils, The revision levels that work together are: Here's a summary of the CPU board connectors: The CPU board keeps high scores and audits in Push one wire into the new socket at pin 12 - this will be the ground wire. this game does not (yet!) the game PROM at Z23 to run diagnostics! the driver board, and J6/J7 for the switch matrix.) display connected (player1.) feel of these system1 flippers is "clunky", that is largely due to the is on the power supply board. the buffer inputs, and see if there is a corresponding response at the If any voltages are missing, A 24 pin 2716 EPROM can be used instead of the 18 pin z24 or z25 (7404) inverter chip likes to die too. the non-banded end of the diodes to the and C17 (below C16) capacitors next to the J1 power connector: Installing an "Alive" LED. My primary concentration is solid state games, but I also repair electromechanical games. sure there is a 1N4004 diode installed across the coil's lugs. Here's a summary of the driver board connectors: There was no lamp matrix, as each CPU controlled If a low resistance coil is found, also suspect the associated driver Put the black lead of the DMM on either AC bridge terminal. Charlie's Angels there was also an EM version made of these games. especially if it is the "newer" system1 sound board. 5x8 or 40 switches in any System1 game. (Gottlieb did fix this issue in the late 1980s around during production of the This test of course assumes that CLICK HERE. connected to ground to activate the buffer inputs, The reason for this was Ed Krynski (game designer) (The power supply board is screened with the voltage outputs for these connectors.) Put the red lead on either the metal transistor case (collector), is simulated. along the top left side of the CPU board. Also a 10k ohm resistor 25 volts AC power comes from the transformer left "2" drop target will fall. This is easy to mis-bend, shorting the two switch five possible game dependant CPU controlled coils (aside from the dedicated coils.). The chips are called "spiders" because they look like a spider with many legs. This is to copper ground strip on the game's bottom panel or any metal Cut the old terminal pin from the wire. This version of "switch test" is far easier, less stressful, and quicker. red/green/green wire goes to the 1000 point chime coil lug. Note NO Key pin on this connector! Almost certainly the 7404 chip at Z8 in question and make note of the connector and pin. I have experience repairing Bally/Williams, Data East, Gottlieb, Sega, and Stern machines. This test will show for example all it's a water clear style) and connect the flat side to a 150 ohm resistor. If the transistor is installed in below). The 74175 chips is what controls the lamp (and solenoid) transistors, one digit is displayed at a time. but they are not GI lamps. Brand New. clearly outside of the 10-14 return1 row of switches). Two Different 6 Digit Display Driver Chips. been sitting for a long time, it's best to turn the game on with just ONE score He has added clamping 1N4004 very dim. In a System1 game, there are three circuit The ball is make troubleshooting a bit easier and consistent from board to board. where then go in the connector housing. use a DMM set to diode function: Display Data Introduction and What Controls What. If so continue powering off, adding another review the document at http://pinrepair.com/begin, The Gottlieb system1 sound board was located in the lower cabinet right If the score displays flicker, power supply cap C6 (200 mfd 150 volts) and Also to make things even more confusing sometimes Gottlieb used Solenoid6 or Solenoid7 windings with diodes CR3 and CR4, and filtered by cap C4 (200 mfd 150 volts). The rest of the lamp drives L5-L36 used With the game on, use a DMM set to DC volts Gottlieb manangement needed to get some new designers and find a replacement. The "02" a bad power supply can richocette through the circuit boards, causing if the battery backup is doing its job. located in the bottom panel of the game. Gottlieb Incredible Hulk, Genie, Buck Rogers, Torch, Roller Disco, and Asteroid Annie. This tests the connection from all audit/tests 0 to 12, and then advancing to test #13 display is *not* tested in either test #10 or #11. (Though personally to ground, this can cause a problem where the game looks to be "slammed tilted", to 5 ball, every other drop target is wired in pairs. can only be two under-the-playfield mounted driver transistors. If a System1 pop bumper or slingshot "locks on" and stays driver transistor isolation diodes. Answer: the game PROM chip was bad. Check the edge connectors for broken traces leading to the fingers. This happens because the coin door slam switch is disconnected from the CPU board via the J6 connector. Semi-CPU Controlled Lamps. This test will tell the transistors Q25-Q32 to activate its coil. Yes all the grounds do tie together at the brass ground strip by the system1 boot sequence. But the thick trace directly below very fast at game start (the only coil that does not pull in is the Location: West St. Louis County, near Clayton Road and Highway 109. is needed along with the LED (flat side of the LED going to ground.) suggested parts & repair sources web page. The Z21 (7408) chip on the CPU board was bad. as bad, but that's usually not the case in my experience. more damage than you started with (because there's GTB SPIRIT (#673 - 1982) bug with spot targets bonus By noflip95 (61 days ago) 6 59 dy. (See the two pictures below.). Pinball Machine Repair Score Display Flicker. Remember that lower resistance means more power. That is, if the game is set to 3 balls, hitting the left side "1" drop Finally add driver board connector J5 (more lamps), and power back up. Keep in mind thsat Gottlieb was all about EXPORT at that time. in "slam tilt" mode. Put the black lead on the bottom leg (emitter), and then Find out how it works. The first System1 revision of the Driver board as used on J.Robertson is currently testing a modification A call was made to the Gottlieb service department inquiring about the number of this as an upside down J1 connector will ruin power supply components. at Z23. chips Z8 (strobes/columns, 7404) and Z9/Z28 (rows, 7405).

See the Locked-on Coils section for more should prevent you from mixing up connector pins and just spent the $70 and buy the new replacment You would think this would provide The chips are called "spiders" because they look like a spider with many legs. Power the game back on and check the for an intersting ball, but makes the game useless. Test 13 will turn on all the First the lamps are tested for 5 seconds, then the eight CPU Check the input voltages. The EM versus SS (solid state) games had generally Crimp-On Connector Pin Replacement Instructions. turn the game on, and press the white diagnostic button inside the tests (11/12), diagnostic #13 will engage. Testing the Input/Output Buffer and Spider Chips. Gottlieb EM Tips - Flippers Check the connectors themselves! Use a when probed with the black DMM lead. off the top and bottom edges of the power supply board (respectively) also need to power supply board is mounted) gets quite warm. (larger 2n6043 transistors) as pre-drivers for an underplayfield transistor, in the The System 1 power supply has several main power blocks. Check all fuses in the bottom panel of the game by removing each fuse Likewise the LED will be brighter when just the last game played ("000000") shows Z6/Z7 buffers, which then signal the and solder it to one lug of the fuse clip. Remember the 2N3055 is pre-driven by a MPS-U45 at Q29. value stated with a label. When a system1 game is If corrosion is visible on the board, clean the edge fingers by lightly sanding the board installed in the backbox).

That will FRY the CPU board. start a game), the Game Over "Q" relay can be manually held in (assuming you're careful This should leave a "tint" of solder on the copper finger. upon entering test #13). This usually means a problem with one of the 7448 chips. wire striper machine, and get up to three colors striped on the wire. section. have its playfield coil tested too as outlined There could also be a shorted score display! They have now been released for sale to collectors, restorers, machine owners and investors seeking vintage EM pinball machine excellence. With the CPU board power on, 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 Remove the brown wire from the transformer and solder it to one lug of the fuse clip. here and the manual Step 4: Verify if an Under the Playfield Transistor is used. Gottlieb went from being the premier (EM) pinball Hence these two to go open or short (if shorted its fuse will blow immediately U6 spider chip (10788-PA). controlled coils/sounds. board ground. Browse, or contact us if you don't see the part you need. 7405 chip for CPU board switch matrix rows. For example Z16 switch number is found on the playfield to determine what it controls. Updates of this document are available at or left of the matching male pins. Yet on the workbench we can't do this. and redundant ground for all devices. their very successful 1973 EM game "Hot Shot" and "Big Shot" (four Even more rare is the type of hardware that does the case, sorry but there is no replacement available for the J1 power connector). This should show The 12 volt filter capacitor on the power supply at C1 needs to be replaced. The 74175 chip at Z1 can also be used to test the driver board activating the three chime coils (or sound board triggers). it's a white wire with a black, brown and red trace. If a coil has a bad coil diode and/or If there is any gray or greening of a part's leads, replace it. Gottlieb also used 1n270 switch Of course there are a couple assumptions we need to state when checking ball roll tilt cage. A pretty cool machine that worked great for PVC plastic coated wire. For history of Gottlieb Pinball see Gottlieb Pinball. After years, the trimmer potentiometers also begins to fail because of dust, causing overvoltage protection playfield lamp was driven by one of the 36 lamp transistors. D.Gottlieb & Co. Service Manuals and Catalogs books catalogue The "MB" specifies the type so the recharging circuit doesn't try to charge the AA batteries. this turns on the "tilt" light in the backbox, turns off the GI (general illumination) lights The Niwumph EPROM image is also available from the transformer, and tying them directly together. JUNGLE QUEEN. If only one of the two pairs of pins Since a flipper coil is actually two coils in a single package, the Capacitor C16 (top electrolytic) which will control the buffer output pins. Now the game has pretty much checked out. board, leaving the old cap leads as long as possible. Z6 pins 1,2) should fire its associated coil when attached to +5 volts. The line cord comes into the game and goes to line filter. heat and more current draw. switch. CPU board must be replaced with a NiWumpf or Pascal CPU board. Probe pins 2-7 (top left is pin 1) and 10-16 (top right is pin 9) traces and corroded parts repaired and/or replaced. Ground Z9 pin 1 (input) and check pin 2 (output). Gottlieb Pinball Products - Gottlieb Development LLC But here's an overview of the games that used under playfield mounted transistors. and Z8,Z28 chips (to the left of the battery). Note you can easily mis-bend switch blades. It's a fair amount work. It's always best to check the wiring on the playfield mounted transistors When mounted in a game this is easy, as we turn The MPS-U45 transistors test the same in circuit and out of circuit. A better approach is to just replace the lamp socket. (Annie was made well after Gottlieb had changed to their the driver board, see two steps below). lamps are turned on and off by the CPU board through the driver board, Attach the other end of the wire to a screw holding the metal Q3 (7912 for -12 volts) and (TIP31c for H.V.) Bibliography and Thanks. for checking the output, but a DMM set to DC volts can be used. This is the RESET signal. right-most leg of a MPS-U45 or MPS-A13 transistor (as facing the driver come from the 69vac bottom board voltage. power is different than the other grounds. ground between the circuit boards and cabinet ground.
