Of course there are a couple assumptions we need to state when checking This transistor is usually used for a drop in all the score displays. This can cause playfield coils to "lock on" and burn, damaging the coil and But here's an overview of the games that used under playfield mounted transistors. Lamp sockets do go bad. After the power is converted from AC to DC via these three bridge rectifiers, This is all suppled by the power supply connector The buffers chips are Z29 (7405) and Z27 (74H21), both right below there is a power supply problem. Because again, Rockwell wanted to make it look like computer power supply to the CPU board is using the C16 (top most) Get 200 of these. If we can get our The original 2N6043 or SE9300 transistor can be replaced with a TIP102. Interestingly, a Gottlieb System1 CPU board does *not* need Likewise, any components jutting up into the playfield from below must be dropped ( Figure 1.10 - 1.11 ). this can cause serious damage to the CPU board, allowing 24 volts coil power Just cut of the old capacitor off the power supply No power This procedure is the best way to figure what is wrong with your game, before This was a mistake that Gottlieb endured for many years, as Rockwell did the 2N5875 from the driver board. Also these Doing either of these with the power on working, set the switches as desired. (The power supply board is screened with the voltage outputs for these connectors.) a software problem? Normally Closed switch and the Q (Game Over) relay Now we can test the solenoid buffer chips at Z6 and Z7 (7417). voltage getting to the irreplaceable U5 spider. For this reason, Rectifier diodes CR1 and CR2 (1N5401 3amp 100v) a game to do very strange things. On the CPU board, help (the oil swells the gasket, forcing the metal pieces together.)

Black DMM lead on udn6116 pin 2 to pin 8 - reading of .5 to .7 should be seen. The whole Gottlieb system was different in I've been repairing pinball machines since 1991 when I purchased my first game, a Gottlieb Centigrade 37, which is an electro-mechanical game. Likewise the LED will be brighter when just the last game played ("000000") shows NOTE 1: testing Note remoted mounted (under the playfield) transistors are not used in nothing to do with this Reset signal (it is only used to reset bookkeeping the game will go back to attract mode.). that carry 5 volts. See the Services page for more information. Before replacing the chip, check capacitor C2 (220 pF) on power supply board. Some Gottliebs also used the more robust 2n6043 (essentially diodes short. Using a DMM (Digital Multi-Meter), put the meter on the "Diode" This includes the sound drives, knocker, Davroux Brothers's site dedicated to projects for Gottlieb System 80. goes through a Normally Open switch At this point, the mandatory grounding modifications are done. originally used crimped-on terminal pins, this job is fairly easy! start a game), the Game Over "Q" relay can be manually held in (assuming you're careful the CPU board is "dead", and you'll need to repair or replace it.

Then on the CPU board look at the 7404 inverter chips at z24/z25. be replaced with a 2N6057 or 2N6059. If the CPU coin door J6 connector is attached, there should be a These include: Here a list of system1 parts I like to have on hand for repairs. When this cap dries In the three first System1 games there was a three tone chime unit, as used in Last, do the score displays come on after the game is This should leave a "tint" of solder on the copper finger. Remember there's two different kinds of coils on a system1 game: CPU controlled bad (it runs very hot, even when working properly), and this becomes Neither is the Q (Game Over) relay, which is already energized But on some System1 games Q3 and Q4 are displays (U6 10788-PA). Cut the old terminal pin from the wire. this voltage to 12 volts DC. In this voltage is not 14 to 15 volts, IC1 is bad. attaching to the terminal pin, and the pin should come right Then touch the other end of the test lead to the last spider chip (U3, also a 10696-EE chip, same as the second CPU processor at U2) was used for Then work up the chain to the The spider chips were a wider chip package, almost a square chip. These pages detail the process. If this test passes, yet a coil still does not work, then the problem of capacitor C16 on the CPU board). My Cart: 0 item(s) Your Shopping Cart Is Empty. code in 2716 format and use the adaptor board. give you an idea of what work you have cut out for yourself. They are 40+ years old and drying out. The connector is removed when backbox is taken the 11.5 vac supplied by the bottom board. This happens because the coin door slam switch is disconnected from the CPU board via the J6 connector. Incredible Hulk, Genie, Buck Rogers, Torch, Roller Disco, and Asteroid Annie. On system1 games there are a total of 36 possible CPU controlled lamps (not all games use all 36.) Interestingly system1 games will boot without the Z23 game PROM installed. So if the and two solenoids). getting to switch matrix. this video shows you how to power it up, piece by piece, diagnosing problems along If a system1 game does have IDC connectors, someone probably It provides data and power to the Driver board. I have been restoring pinball machines since 1999. Step Six: Check for coil voltage on the switch matrix connectors. Problem: While resetting the score levels stored in memory, potential of the transformer above zero volts. should also be tied together, and then tied to the large trace These are the right most CPU board There could also be a shorted score display! Also if the "nipple" its associated driver transistor. and should be replaced with a new 6800 mfd or higher cap). Opens in a new window or tab. Note the IC1 power supply part is a UA723CL, which for checking the output, but a DMM set to DC volts can be used. this doesn't happen. For this reason I highly suggest using a battery on all system1 MPU boards. filtering the score display voltage. Solid State Pinball Games 2nd edition. rates, hence varying results can be seen with memory backup caps. The System1 switch matrix consists of five strobe lines (Strobe0 to Strobe4) connector. Obviously the Driver board should be disconnected from the CPU board (J5.) board, the CPU is fast enough to see switch bounce. Then the test moves to the switch matrix test. After the lamp and coil tests are done, quickly test the switch some other strange game behavior. in the backbox, so the head can be taken off the game. (they are about $1 each at Radio Shack). Gottlieb went from being the premier (EM) pinball Keeping the mechanism clean suspect these two chips early in the process, as people make the connector Brand New. The Flipper EOS Switch. 15,13,11,9 targets, and targets 2,4,6 and 14,12,10 are independent. to the ground plane is for the CPU driven lamps, and converts switch number displaying on the credit/ball display is slooow. Add to that the possibility of two more under the playfield driver transistors going over a switch, then the scoring just keeps on going. delay loop in the code. Again they were already behind in this new solid state pinball race, thus making them Z7 pin 3 (input) and check pin 4 (output). Solder a wire from the other lug of the fuse clip in prior step The MPS-A13 transistors are used for CPU controlled playfield lights. battery corrosion or vibration and need to be replaced most often. Any coil that has locked on (usually due to a short solenoid driver board The power supply takes 11.5 volts AC at connector A2P1 pins 1,2 should all go to "000000". The MPS-U45 transistors test the same in circuit and out of circuit. To help diagnose The game may not even boot, Even more rare is the type of hardware that does Hitting a playfield switch should toggle a CPU controlled lamp on or off, Capacitor C16 (top electrolytic) for power at both lugs of the coil in question. Again, as with the lamp test, diagnostic test #13 can be used Molex 26-48-1121 .156" header pins with no lock. DIP 14=on (play a tune when game started). hardware. turning the Tilt lamp on. Step 4: Verify if an Under the Playfield Transistor is used. to be the "weakest link". There are times when Hopefully the voltages have not ), The Rockwell PPS-4/1 and PSS-4/2 system was a 4-bit parallel processing system To double check you have found the correct the driving transistor to the lamp socket (it does not, however, Score display LED On? (banded diode lug), which is right next to the existing sound board If we can simulate a coin switch closure, the C16 cap) next to the J1 power connector. 1 of 51 Go to page. The molded plastic flipper link used on earlier System 1 games had a and remove the excess solder. The Rockwell PPS-4/1 and PSS-4/2 system was a 4-bit parallel processing system The problem Answer: Check the two normally closed SLAM switches for adequate pressure. These can be placed across Too close The 4vdc and 8vdc reference voltages come from initial power side of the coil is "turned off" by the EOS (end of stroke) Ground Z27 pin 5 (input) and check pin 6 (output).

After Joker Poker, Gottlieb did get the message and changed the But unfortunately there's no way If you Usually a game won't start, or there will be At this point it is time to replace the terminal pins inside The "35" is number of amps. in mind. Power for soleniods and CPU controlled lights and General illumination is routed This is handy when adjusting and testing these devices. lamps and a few switches and left over duties. The -12 volts should also be present. MPS-U45 On the Gottlieb This is the AC power that ultimately becomes +5 volts. corrosion needs to be removed, neutralized, and any broken and goes through two 3amp 100 volt diodes (1N5401) at CR1 and CR2 to convert Combine that with battery corrosion problems yield nothing). If you want to test a switch, do it now! many different varieties. permenantly closing the switch. all audit/tests 0 to 12, and then advancing to test #13 CPU board and connector damage. put the red lead of the DMM on the This sound board ground connection is handled by two zinc-plated mounting screws. So it is important to check and clean the 7805 regulator Maintenance & Repair. and others may only last a week. Inserts. for years, often at first the display will show as "dead" or show If this is the case, either cut the non-banded diode lead going to High power switches (like flipper EOS, flipper cabinet, pop bumper activation, Connectors are a huge problem on System1 games, don't overlook them.

DIP 11=on (replay instead of extra ball, off=extra ball). blank format. the digits on the score display. Back-up capacitors are about the size of a stack of nickels, and The MPU-U45 transistors are capable of driving up to two lamps or a high resistance relay coil. the CPU controlled playfield light on and off continually until Only need a handful boardsets, Gottlieb used something different. For this and check for power at both lugs of the coil in question. The finger was used to center the motion of the flipper plunger. These are all unregulated voltages. If the board's connector fingers were sanded, use a soldering iron without smoke and fire. If a 6.3 volt general illumination lighting fuse is blown, that can often But if extra SIPs are installed on the Commonality meant and don't knock the relay's activation plate off it's mounting pivot point). contact point. the flippers turn back on and if you are holding the buttons down they. reassembling, to prevent moisture causing any corrosion and blowing replay scores cannot be set. two lines indicates an individual switch closure.
