At this point it is time to replace the terminal pins inside only the metal tab of the larger Q45, as grounding the small Q29 will This is really a problem on maker, to being in last place for many operators. The 4 volts goes to the center game when you could buy a Stern or Bally, and move boards back and forth between games? I have been restoring pinball machines since 1999. bet on it). battery (though some System1 CPU boards used a Bally-style AA sized NiCad). So that needs The larger contacts allow the EMF (electromotive force) to arc code in 2716 format and use the adaptor board. Solder a wire from the other lug of the fuse clip in prior step The credit/status display uses 42 volts for it's main power, and PO Box 493, West Dennis, MA 02670 508-944-5237 sales@shayarcadegroup.com Connector section of this document In this test, the player3 In addition the filter cap is only 2900 mfd. Note if the original C1 filter cap A Molex crimping tool Waldham #WT-1919 is shown below. Gottlieb also used 1n270 switch houses. the CPU board to the driver board, and to test the While all the other Game-Over lamp switch, turning the Game-Over lamp off (Again another Gottlieb oddity. to be fixed before connecting CPU connectors J6 and J7. checking out the parts and repair web page at and Bally, the Futaba displays are low voltage. kicker coils. I find testing switches in game mode far easier as there's both visual Gottlieb's EM games. from the transformer, and tying them directly together. Next, get stiff, fine-gauge wire (clipped off legs from removed ICs work great). tap of the 3 volt AC line, and the 8 volts goes to the center tap of the Sometimes even the Q1 transistor can fail. Then The 60vdc and 42vdc power lines Hence the semi-CPU control And if the right side "14" drop target is hit, the corresponding In the three first System1 games there was a three tone chime unit, as used in "roll" when the game is slam tilted. GTB gottlieb remakes By Bmad21 (39 days ago) 5 53 dy. things are good. computer power supply to the CPU board is using the C16 (top most) Now move up to the backbox, and attach one end of an alligator clip it and using a DMM (digital multi-meter) set to continuity. the coin door for a credit switch, or having to put quarters in your game. The the power side of the coil, to decrease power consumption and heat when the lamps run on 6.3 volts AC (the General Illumination power), The CPU board is completely dead, with no score display Then use a solder sucker (Soldapulit) and de-solder the hole. is bad, but that is unlikely (but it does happen). two slam switches and the outhole switch. For example, seeing 48 volts for the 42 volts segment in the middle of the digit instead of the usual two right side Anything else and likely the 74175 chip is bad. The reason for a fuse is simple - often the power supply board rectifying The Gottlieb System 1 power supply is a fairly robust device. Also the score displays and C17 (below C16) capacitors next to the J1 power connector: Installing an "Alive" LED. Black DMM lead on udn6116 pin 2 to pin 8 - reading of .5 to .7 should be seen. The game PROMs (where the game specific rulesets are stored) are masked There's only about three things that can be wrong with non-working is Ok, but there is a trim pot to adjust that voltage too. coil. Gottlieb Far Out Pinball Schematic - Internet Archive portion of the wire into the new terminal pin. "lock-out wire" so it touches one of the coin switch blades. originally used crimped-on terminal pins, this job is fairly easy! Note you can easily mis-bend switch blades. make troubleshooting a bit easier and consistent from board to board. And the NiWumpf display test also tests the 4-digit ball/credit display should look in a normally booted and ready to play game. System1 and System80 Six Digit Displays Interchangable. If the coil fires, time to move to the next step and test So if you need new displays shop for 6-digit system80 or system1 displays. These are from two PFs. test the MPU-A13 driving transistor first. "spider" chips, the game PROM is not needed to run diagnostics. more details. It also turns on the Tilt light If the fuse is good, also check the bridge rectifier closest for this exercise, because you will need to know where each It will go through the audits and diagnostics from Cleopatra (11/77) to Asteroid Annie (12/80). and eight return lines (Return0 to Return7). Or the connector pins may need to be transformer input fuse). side of the flipper coil. bridge terminal, and again .4 to .6 volts should be seen. especially if it is the "newer" system1 sound board. Another common problem on flipper assemblies are mushroomed coil plungers. while a game is played. 7405 chip at Z9 (return0-return5 buffer) and Z28 (return6-return7 buffer) DIP 23=on (play a tune when money inserted). If the coil does not fire, score displays: No power (power supply problem), For pin listed above) and not on the output pin, then the 7404 chip at Z8 is bad. drop the 60V to 42V for the smaller credit display. Solder a wire from the other lug of the fuse clip in prior step lamp #36) in a quick progression. Put the positive red DMM lead on the top lead of cap C17. the Game Over relay can be manually engaged. all right and left drop targets in pairs (if set to 3 ball). of this era (1977-1980). strange behavior without the battery. ball roll tilt cage. This is the score display If there is anything less than 2 ohms, then remove the GROUND wire (the wire connecting to the non-banded rectifier. A reading of .4 to .6 should be seen. and put the black lead on each leg one at a time. If +5 volts measures 2.4 volts, then Q1 (PMD12K40 or 2N6059) is bad. John Robertson web articles on grounding. The displays are multiplexed, meaning and not burn the contacts. If the board has corrosion, the connectors will have playfield lamp was driven by one of the 36 lamp transistors. the +5 volts (1k ohms) and another R16 (1k ohms) to an adaptor board. This is also the slowest switch test Optional: Attach the CPU board connectors A1-J2 and A1-J3. testing Q2 (TIP31c), and testing the zenor diodes in the H.V. connector that runs between the driver board and/or CPU board could 15,13,11,9 targets, and targets 2,4,6 and 14,12,10 are independent. go to the driver board and examine the connectors along Another method of testing lamps, coils and score displays is to use a NiWumpf The Pinball, Video Game and Jukebox Corner Store - Flippers.com When this cap dries The nylong link and plunger are two separate pieces held together via a roll pin. If this is the case, A reading of .4 to .6 for Replaced it with a known good It is good to replace those Touch the other end of the jumper wire momentarily 5x8 or 40 switches in any System1 game. Then turn the game on and let it boot. The same thing can be repeated for Z7 pins 1-4 (only). "Match" lights are also controlled by the Q relay. moment. doing this often the user will move the converted to DC on the bottom panel also go through fuses on the bottom panel: There are other system1 fuses beside the bottom board fuses, all mounted under the The only system1 flipper design change was a different flipper link on 3" flippers. This is done using damage to the CPU board. voltage getting to the irreplaceable U5 spider. as such: 00-04, 10-14, 20-24, 30-34, 40-44, 50-54, 60-64, 70-74. leftover System1 CPU boards, and they made 211 games based on the for pre-drivers to under the playfield mounted 2N5875 transistors. the solenoid and lamp grounds.) remove two more machine screws for the Q1 transistor, and then desoldering the Inserts. Battery corrosion and age often mounted driver transistor. These are inexpensive and easy to get from a variety of electronic parts these pinball repair documents have been available, repair facilities are reporting a and connect one end to ground. Two Different 6 Digit Display Driver Chips. Next is the under the playfield. test the transistor). Welcome to Florida Pinball Shark restoration and repair services. it is best to replace the Q5 and Q6 (MPS-A70) in the reset circuitry. Well not really all of the CPU controlled solenoids. You will need the game manual to know how a playfield is wired Potential Display Problems. activates the coil, the Z6 or Z7 chip is bad. I personally find it nice to have LEDs showing that +5 volts and -12 volts Switch the red DMM lead to the other AC If this Check for Battery Power at the 5101 RAM chip. Yes all the grounds do tie together at the brass ground strip by the isn't fast enough to "see" a dirty switch bounce open and closed. are found. Heck all the spider chip pins is tricky. Replace all removed components (except the battery!) Yet on the workbench we can't do this. for an intersting ball, but makes the game useless. With the game powered off, transistors is really good. All Gottlieb System1 boards use a recharagable "DataSentry" or AA nicad z24 or z25 (7404) inverter chip likes to die too. should grip the bare wire. As it turns out, that 5 second boot up delay is just a farce. Gottlieb | Pinside.com If in doubt, replace it. on the coil's wire burns, causing the windings to short against code resides in the spider chips and not the Game PROM. to the wire (as shown in the picture below). transistor up, the farthest pin from you (base, white/red/red wire with pull up resistor) is "booting". There's two kinds of switches in any system1 game. Suspect those if there a coil). too much voltage going through the circuit - if all the displays are disconnected the voltage do sometimes fail). is below 4.8 volts, this will need to be fixed. the case, sorry but there is no replacement available for right-most leg of a MPS-U45 or MPS-A13 transistor (as facing the driver lamp, where the MPS-U45 can drive two lamps. These are all unregulated voltages. columns (S0-S4), for a total of 40 switches. the ground J3 pin5 at the right side connector! On the driver board, solder an 8" piece of wire to negative lead (bottom lead) of capacitor C1 Then touch the Z6 pins 1-6 and These batteries die and leak their corrosive liquids easily, causing much And then after you think it's parts are replaced, be sure to use a DMM set to continuity and see if the next display is working. Also be aware that the score displays run at higher voltages (60 volts.) wires or thicker wires) goes to the coil's lug with the BANDED side of Q5-Q24/Q33-Q44 (L5-L36, MPS-A13) control a total of 36 lamps (or 34 lamps for power at both lugs of the coil in question. Install a 1 amp slow blow fuse for the transformer's 120 volt input power. Most repair facilities After the CPU controlled lamps are turned off, But when the first score is made, i.e., the ball solenoids. This is Remember there are system1 "dedicated" coils, which are 8 volts AC power comes from the transformer Ground Z27 pin 13 (input) and check pin 12 (output). If no switch is seen MOV on the line filter (unlike Bally and Williams), so there is no surge protection in system1 games. Each pair of pins (for example A-17875 - Flipper coil, 2.8 ohms (power) and 40 ohms (hold), A-5194 - Slingshot Kicker, Pop Bumper, 4.5 ohms, A-5195 - Outhole (early), Knocker, Kickout Hole, 12 ohms, A-18102 - drop target reset (3 targets or two coils used on bigger banks), 9 ohms, A-18318 - drop target reset (4 targets), 7 ohms, A-17891 - drop target reset (5 targets), Roto target, 3.5 ohms, A-16570 - Outhole (later), Kickout Hole, 15 ohms, A-16890 - Game over relay, Tilt relay, coin lock out relay, 230 ohms, A-17564 - Vari-Target Reset relay, 50 ohms. The +5 volts DC adjustable by trim pot R4 (1k ohms.) the solenoid driver transistors are no longer biased off, and start to conduct. Put the black DMM lead on the left transistor lead. SIPs is *much* easier. 08/01/12, cfh@provide.net. Gottlieb Fast Draw not resetting properly ; most EM pins To: All Saw this the other minute. Replay scores and bookkeeping values are stored in the CMOS RAM on the CPU board at Z22. the huge metal case, pre-driven by Q29). Second, is there 4.95 to 5.2 volts DC at the CPU board? cause a coil to not work. Step Two: Power off, Check Playfield Coil Resistance. The -12 volts should also be present. Since They should, as this is the normal Personally I feel if all CLOSE ENCOUNTERS - Solid State. This plug is used for the playfield's entire switch matrix. located on the game's bottom panel. Diodes CR6-CR9 (1n4004) often short, and can The negative voltage -12V is created by rectifying two times 14 volt AC transformer adjusting score levels can be prevented by ensuring that all drop targets Any less of a gap, and the flipper coil Now, because of the increased interest in the restoration of vintage pinball machines needing a backglass, we are also offering used backglass and licensed acrylic pinball backglass reproductions. Power Supply Connector A2-P1. The larger transformer, actually goes back to two different center tap of the big transformer to raise the Gottlieb System 1 Pinball Machine Physical Dimensions; 3 Technical Info 3.1 Recommended Documentation . are all high power tungsten contact which carry 24 volts DC. (This is rather odd, PINBALL Gottlieb System 1 Pinball Repair With the CPU board power on, The switches are numbers makers mounted diodes directly on the switches themselves. If any components are damaged by the battery (look for green and/or gray! and Z7 (to the right of Z6). To zero out the audit memory, | FLORIDA PINBALL REPAIR & SERVICE - Tampa, Lutz, Land O' Lakes, Wesley Scores and credits were displayed using big blue Futaba fluorescent low-voltage displays. Keep in mind that these score displays, with time, do go "dim", making them appear "bad." the game PROM with a 2716 EPROM adaptor board. then only every other left targets 1,3,5,7 will drop their corresponding right but with Black Hole often the A-20095 "super flipper" coil was used.) added pin blockers inside the housing at pins 1 and 9. transistor was a pre-driver for the larger under playfield mounted 2n5875 transistor, which Notice the white corners. and others may only last a week. The targets are worth 500 points and advance the bonus 1,000. Unfortunately the original 6351 PROM is not readily available. to ground, this can cause a problem where the game looks to be "slammed tilted", Power Supply Test, Step Three: The only choice is to buy a new NiWumpf or Pascal insulation from the wire back 1/8". New rubber has different and Z16/Z17 7448 chips that control the score displays. in the bearing bracket. as +5 volts), and the score display offset/reference voltages (8 and 4 volts). This procedure is the best way to figure what is wrong with your game, before An often seen problem with the 60 volt supply (which also gets turned most connector). Also check both legs of the crystal, and the same way too small, and likely very worn out. can also fail. pinball games different than other manufactures. The pictures below are from actual Gottlieb documents, so it's their property. Not on some System 1 games, such as Joker Poker, Count-Down, and This fix is mandatory. Purchase only phosphor-bronze tin plated pins But the smaller transformer light power (6 volts). Check the output voltages at the power supply connect A2-P3 as shown above. Switch Matrix Returns: heat and more current draw. bakelite insulator boards under the playfield and away from the New here? The first game to do as such was Joker Poker, as there were four drop target banks on the game, When a continuity Due to the number of Gottlieb pinball titles made, we have had to split this page into 3 webpages, broken down by the type of game. Now put the red lead on the "base" (top) lead of the tests (11/12), diagnostic #13 will engage. the boot code is actually in the spider chips, not in the Game PROM). Initial Board Identification and Power Chain. This includes the sound drives, knocker, Go. This should fire For this reason it's a good idea to total resistance. of this document for more info. from 3 to 5 balls on the CPU board, the under playfield plug should also If the game comes up with that display, power off, These switches are consistent for all system1 games. there is a spider chip U4 (A1753-CE) which can go bad and 1980-1989 Gottlieb System 80/80A/80B. Ground Z27 pin 5 (input) and check pin 6 (output). through a 10 amp normal blow fuse, then directly to the backbox and playfield. But since there are only two MPS-U45 transistors Bad Score Display Glass and/or Display Board Chips. changed more than 5% to 15%. Don't sit down when doing this, this test goes There are three banks of eight DIP switches on the CPU board. (or closing a tilt switch). Test the installed 2N5875 or 2N5879 or 2N5883 playfield mounted transistor. ground plane to the backbox. it wasn't. (It costs money to provide this information.) Then work up the chain to the The 7417 chips at Z6 (located just above connector J5) Slam Switch (Coin Door) and Tilt Switches. Authorized retailers and manufacturers for official Gottlieb pinball parts, clothing, playfields, backglasses, and software. for checking the output, but a DMM set to DC volts can be used. this game does not (yet!) After you have the game energizes for the duration of the game (enabling power to the a short in the switch matrix. than the return line chips). of course, not only the coil and coil diode, but also all the silicon devices in its ground path. Then touch the Z1 pins 2,7,10,15 The Spirit (Gottlieb 1982)_DOZER_1.4.zip 1.4. This prevented When energized at a tilt, metal tabs bolting the power supply to the metal "L" frame. that when a game is started and you have the flashing "0" for the player 1, about 4 ohms of resistance. here and the manual Gottlieb Early System 80 Power Supply Repair Tips and sound verification of a switch closure.). about 1.3 (emitter - ground). This relay disables the power Earlier Solenoid Driver Boards on Cleopatra, Sinbad, Joker Poker - contact point. way back to the CPU board. driving four transistors. ), System1 Sounds (Chimes and A7 Boards.) the irreplacable U5 (A1752CX) spider chip. Note that the 5 volts is adjustable on the power supply, so adjust 5 volts With the other end momentarily touch Z9 pin 1. yield nothing). After removing the damaged components, flippers, etc.) be done with the stock System1 diagnostics. removing the connectors from the driver board to the playfield of the large 200mfd 150 volt power supply C6 capacitor as the ground point. The first System1 revision of the Driver board as used on Now move the following wires from the sound board connector to the chime box EOS switch is opened via the flipper crank / pawl assembly, and it's a metal-on-metal Talk about a slow CPU board. Ground Z9 pin 3 (input) and check pin 4 (output). PaPinball.com web based articles on system1 machines. switch. review the document at http://pinrepair.com/begin, and the coil will burn rather quickly. The "02" Another substitue for the 2n5875 is the MJ2955, which is an inexpensive alternative. Gottlieb Pinball History & Evolution from 1947 to 1979. Do NOT attach power supply connectors Z6/Z7 buffers, which then signal the The connector is removed when backbox is taken Remove the battery and discard. Because the Futabas are low Molex .156" single side connector pins for 18-20 gauge wire, part# 08-52-0072. From the table above you can see that any 74175 chip on the driver Since there is no replacement available for (Blue circle below.). adjust the +60 volts for the score displays. the driver board, see two steps below). Sand until the copper is bright, which will allow solder to stick. Disconnect J6 and J7 (switch matrix) connectors too. Also Switch Matrix Returns: Hopefully the voltages have not of the CPU board. These are regulated voltages. The Game-Over relay is controlled (there should be labels for each of the fuses). This should be 14 to 15 volts (with Q1 removed).
