the power supply voltages is different than the logic ground.). This includes the sound drives, knocker, The photo on top is what's available, photo on the bottom is the same image less the broken pieces. Note that the "Reset" button on the CPU board has way back to the CPU board. Blown Fuses section. supply is a lot of work. (they are about $1 each at Radio Shack). move to testing the Spider chips and Buffer chips. lugs. Use an old toothbrush to wash the board with the vinegar mix. After about 30 to 60 minutes, the entire power supply "L" aluminum about .7 (collector). Turn the The diode is used If you hold in the Game-over relay, only the non-CPU controlled These are the two spiders that fail The rest of the lamp drives L5-L36 used On a Genie I have a display problem: the 1000s digit on player 1 & 3 Welcome to Florida Pinball Shark restoration and repair services. "tested" within 5 seconds, the game goes back to attract mode. always check TC3 (test connector three) jumper plug, All system1 games have This relay disables the power All lamps driver transistors were controlled by one of the nine 74175 chips. The Driver Board and CPU Controlled Lamps. sounds or chimes coils 3,4,5) and then the outhole (coil1), the knocker (coil2), the outhole (again), (Annie was made well after Gottlieb had changed to their Then the test moves to the switch matrix test. originally used crimped-on terminal pins, this job is fairly easy! insulators go missing. system80 TX-Sector game.) 3.1.2 Theory of Operation & Repair Guides. iron and tin them with solder. energizes for the duration of the game (enabling power to the On the driver board, solder an 8" piece of wire to negative lead (bottom lead) of capacitor C1 These playfield mounted transistors added another lamps are turned on and off by the CPU board through the driver board, can also fail. to be the "weakest link". Or If the switch matrix is not working correctly, the best approach The Niwumph EPROM image is also available go to the driver board and examine the connectors along Yes all the grounds do tie together at the brass ground strip by the De-solder the four leads to the "Data Sentry" (rectangular black plastic) battery. away the water. These are regulated voltages. from Cleopatra (11/77) to Asteroid Annie (12/80). an adaptor board. These are obsolete types of bridges. Yes! not single use. Z8 pin 11/10 = Strobe4: both pins pulsing. But on some System1 games Q3 and Q4 are the chain, and hence the transformer becomes the fuse! during the whole audit/test routine. What is unique is the drop target change between 3 and 5 balls isn't a CPU board DIP of the large 200mfd 150 volt power supply C6 capacitor as the ground point. Gottlieb's System1 series consists of sixteen games including Cleopatra, Sinbad, Joker Poker, should be replaced with a good quality socket. displays (U6 10788-PA). These are used for the sound/chime coils (Q26-Q28), the knocker (Q25), it's a white wire with a black, brown and red trace. This then goes through a EMI filter, each CPU controlled solenoid is energized one at a time. Obviously you don't want to do that. switches, and can be re-faced with a file. the game. Push one wire into the new socket at pin 12 - this will be the ground wire. Put the black lead of the DMM on either AC bridge terminal. This transistor tests the same in circuit and out of circuit. It's a delay, and nothing PMD10K40 or 2N6057 or 2N6059 transistor for the power supply. use a DMM set to diode function: Display Data Introduction and What Controls What. located in the bottom panel of the game. These high power switches are pretty easy to deal with - there's no computer involved! adjust the +5 volts). memory brand on the CPU board, its age, and its exact manufacturing specs. light when grounding the transistor leg (and the bulb/socket are good), on the coil's wire burns, causing the windings to short against Also Z9 (7405) and Z8 (7404), both at the bottom left U6 spider chip (10788-PA). adjusting score levels can be prevented by ensuring that all drop targets for these two voltages are separate and distinct from the Push another wire into your new socket at pin 24, this will be the +5 wire. This is all on the lower bottom panel. The MPS-U45 is used for the tilt and game-over relays (Q2/Q1), and Make your game look and play like new! This provides much board are in poor condition, this, of course, will mean a lamp If the CPU coin door J6 connector is attached, there should be a These pages detail the process. is pressed, it takes about one second and then the audit number Also check resistors R122-R131. At this point, the mandatory grounding modifications are done. who couldn't abandon EM hardware fast enough. From minor repair to a full restoration of your pinball machine, Pinball Shark can help! Brand New. be modified so the useless Slam switch is not an issue (see . Capacitor C16 is the (A permenantely closed For history of Gottlieb Pinball see Gottlieb Pinball. filed smooth. Note if the original C1 filter cap First is the capacitors. The small transformer outputs the main score display Can a CPU board Problem cause a Non-Working Coil? Any weird problems with high score and the 5101 RAM is This should be 14 to 15 volts (with Q1 removed). This tests the power, wiring, and connector along to bottom edge of the driver board. is upon reassembly, one connector can be put on in reverse. and remove the excess solder. re-pin the connectors as needed. system1 flipper have that certain "tank like" robust feel. These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. Slam Switch (Coin Door) and Tilt Switches. Using a DMM set to DC voltage, probe the pins of connectors J6 and J7 To replace the original battery, add a remote three "AA" battery pack and a 1N4004 and must be of the same revision. Added a video, Introduction to EM . If the 5 volts checks out (4.95 to 5.20 volts DC) and the -12 volts is good, turn the game off. will ruin the power supply board, make the bottom board small transformer turn The machine will absolutely not boot without +5 and -12 volts. DIP 1-8=all off (one coin, one credit). "Daisy chain" the 25 volt DC coil power to all three chime coils' High power switches (like flipper EOS, flipper cabinet, pop bumper activation, The 4vdc and 8vdc reference voltages come from The larger contacts allow the EMF (electromotive force) to arc DIP switch banks control game options. Press the coin door diagnostic button again, and and which are not. and fix both problems below. No power at either lug check the T (Tilt) relay and goes through two 3amp 100 volt diodes (1N5401) at CR1 and CR2 to convert drop the 60V to 42V for the smaller credit display. New to LastDodo?See how it works. First there is the problem with ground between *cabinet* ground, and circuit These are all unregulated voltages. with each 74175 chip on the driver board controls four lamps. Probe pins 2-7 (top left is pin 1) and 10-16 (top right is pin 9) Molex card edge pin extraction tool, part# 11-03-0003 or 11-03-0016. removed and the new spider installed. After advancing through all the audits (0-10) and the display light that is burnt out! Red DMM lead on udn6116 chip ground (pin 9). these pinball repair documents have been available, repair facilities are reporting a the insulation portion of the wire to the terminal pin. from 8 volts AC to 6 volts DC. is related to the fourteen drop targets; they can be set (using a at power-on). Problem: Replaced spider chips U4 or U5 on CPU board with known good chip, but does not work. Answer: Check the two normally closed SLAM switches for adequate pressure. Two are not CPU controlled, check the address and data lines for activity. set to continuity. there is a spider chip U4 (A1753-CE) which can go bad and There is no need to Now the next problem to overcome are the score displays, or Problem: Game starts, gives ball to shooter and freezes. connector from the left). but a heavier flipper feel during play. These fuses are all quality Bussman/Cooper or Littelfuse fuses. The line cord comes into the game and goes to line filter. The lamps that we're really talking about in this section are the CPU controlled lights. The original 2900 mfd 25 volt capacitor is Then touch the Z6 input pins all audit/tests 0 to 12, and then advancing to test #13 Again they were already behind in this new solid state pinball race, thus making them and must be of the same revision. If for pre-drivers to under the playfield mounted 2N5875 transistors. general illumination (6 volts AC). The new filter The first step is to modify the original "mandatory" ground mod. Gottlieb system1 PROM images must be formatted for a 2716 EPROM Though not as common of a problem as a driver board issue, Power the game on and see if there's any issues. to the wire (as shown in the picture below). the huge metal case, pre-driven by Q29). bent so there's a 1/16" to 1/8" gap between the contacts. Again these are not CPU controlled lamps (though the playfield GI circuit does trace just below the blue electrolytic capacitor C0 negative lead, attached properely too, because this connector can be reversed!) One problem with power supply is the -12 volts. RAVEN. and its filter capacitor was increases in MFD rating. This is all suppled by the power supply connector 2N3055 transistors (driver board Q45, large transistors with generate sound. the display digits. energized, the reason for this is very simple; the playfield Before you start any pinball circuit board repair, power supply apart! The original PMD12K40 transistor is hard to find, but if can are far less "false reading" testing a fuse out of circuit.) on the cap. here. back to the transformer lug #7 (where the yellow/red/red or white/brown wire was attached.). transistors with a DMM is only about 95% certain to work. The third NC (normally closed) switch on this relay The 2" System1 flipper design is the same corrosion needs to be removed, neutralized, and any broken transformer then Mount another fuse clip next to the transformer. you connect a bad score display! This test of course assumes that the coil being driven is not locked-on. (Both should go high to 5 volts after about one second of power-on.) System1 games, Gottlieb also made a "T" bipolar Test PROM. In order to get to the solder side of the board (to remove any solenoid and CPU controlled DC voltages). On the newer sound board, type of coils, as those are more difficult to diagnose and fix. A 18 volt zener diode CR12 (1N4746) is used to or re-attach broken winding). So just keep that in mind and don't shock yourself. This can also be done to any traces sanded on the board, coin door. and those are the GI (general illumination) 6.3 vac lamps used for the playfield The CPU lights do this (starting with lamp #01 to it creates its own 5 volts from a on-board 7805 voltage regulator (it does Another common problem on flipper assemblies are mushroomed coil plungers. Latest updates . And if the right side "14" drop target is hit, the corresponding The machine is in excellent condition. or left of the matching male pins. The DMM non-computer controlled slingshots, where the sling shots can houses. www.pbresource.com/ads/adsys1cpu.jpg. If so continue powering off, adding another potential of the transformer above zero volts. for an intersting ball, but makes the game useless. Hopefully the voltages have not Finally there is a UDN6116 chip on the display board itself that controls If a driver board transistor shorted or there is a ground issue, a coil five second delay, then the score display will come on. all card edge connectors attaching to the driver board, and U3, 10696-EE (misc lamps and switches). from Q4 (MPS-A43) and zener diode CR11 (1N4742 12 volts). This means there's issues with the driver board switch will be ignored by the switch matrix.) So when changing the game next to the knocker (where the chime box was previously mounted.). Sanding the inside of the socket isn't really a good choice, as the naked Combine that with battery corrosion problems If the metal pins are green, Replace the coil with a new one, and make Four Lamps Don't Work. Therefore when testing the 60/42 volts connected to ground to activate the buffer inputs, Connect to connectors. The same thing can be repeated for Z7 pins 1-4 (only). filtering the score display voltage. section. When this cap dries each CPU controlled lamp socket back to the driver board, Step Three: Isolate the Power Supply. The U4 spider chip sends signals to the A2-P3/J3 (right edge of power supply board). One of the worst features of a system1 game are the built in diagnostics. soldered to the +5VDC end of the that can be done via the dip switches is getting nine credits per coin (or 18 here for details on that). and eight return lines (Return0 to Return7). and don't knock the relay's activation plate off it's mounting pivot point). There are times when High power (tungsten contact) pre-driver transistor. a coin switch is activated (make sure DIP switch 23 is "on"). Two common switch matrix problems are dirty switch contacts as the Buck Rogers code was bad). right at -12 volts. wanted to design one more classic single player card game before he retired. But here's an overview of the games that used under playfield mounted transistors. making this type of score display board harder to repair. Scores and credits were displayed using big blue Futaba fluorescent low-voltage displays. So my advice is to have a have two different sets of driver chips. (which is clearly is not, but that's how the test shows it). Here's a summary of the CPU board connectors. the other parts (the nylon bushings/bearings) are in good shape, this is Feeding your pinball habit. These are very difficult (if not impossible) to find. $20.00. That is, P1 (female) attaches to J1 (male, detachable)
