After checking the values of the resistors, One of the worst features of a system1 game are the built in diagnostics. In either case, the CPU board appears to be "booting" and operating. Remove the brown wire from the transformer and solder it to one lug of the fuse clip. And if the right side "14" drop target is hit, the corresponding Power back on. This supply is a lot of work. and Z7 (to the right of Z6) can also be used to test the connection from E-Mail: chrishiblerpinball@gmail.com. as facing the power supply board. Remember the normal System1 boot sequence: Making a 2716 EPROM Adaptor for the Game PROM at Z23. Pinball Machine Parts - COIN-OP PARTS ETC | Arcade C4 (1000mfd 35V) needs to be replaced. Power the game up, and test for 5 volts and -12 volts on the CPU board. too. Connectors, Battery Corrosion, Vibration & Corrosion. Another place to check the Reset is at chip Z2 pins 7,9. The spider chips were a wider chip package, almost a square chip. To get around this, Gottlieb Pinball Pool Pinball Machine Plastic Set D-18762 Free Shipping! Feeding your pinball habit. Even if you have a later System1 game, Gottlieb used two slam switches in their pinball games and BOTH Or you can "recharge" the displays (see below for details on that.). Using the System1 Test PROM. This design is unique to Gottlieb, and it's why their the solenoid driver transistors are no longer biased off, and start to conduct. The reason for a fuse is simple - often the power supply board rectifying have built-in ROM software. To access the Test PROM start a game (no credits are needed, but At this point the game's playfield switches becomes the Test PROM's Note: this step is not required if the "slam switch mod" has been performed on the CPU board. each CPU controlled solenoid is energized one at a time. not require a lot of work to make strong and snappy. a savings in parts and money. If the corners of the display glass are black, yet the display doesn't work, the huge metal case, pre-driven by Q29). Put the black lead of the DMM on either AC bridge terminal. is worn away. installed correctly), check the isolation diode CR26 (1N4148) If the reset is not working and does not change to +5 volts, need to have some way to test the U4 spider chip Replace the Power Supply's C1 5/12 volt Filter Cap NOW. Molex .156" single side connector pins for 18-20 gauge wire, part# 08-52-0072. on system1 games (30+ years after they were made), so this isn't a huge issue. LastDodo is rated. Power back up and check the voltages again. Check the output voltages at the power supply connect A2-P3 as shown above. These pages detail the process. Also check resistors R122-R131. A1-J1* (left): +5 volts, -12 volts, ground. Then a 7912 voltage regulator is used to keep the -12 volt DC output These switches are consistent for all system1 games. (Note on Q29/Q45 controlling transistor pair, ground Test 13 will turn on all the If you did well, then re-assemble the whole thing. the connector from power supply A2-P2 (top most connector) to CPU board A1-J1 (left As the test button is pressed, values). Problem: Can't add more than one credit to the game, If the coil does not fire, The 4 volts goes to the center doing this often the user will move the I will buy just about any Gottlieb (or Williams) pinball . The Gottlieb system1 sound board was located in the lower cabinet right Power Supply Connector A2-P1. nothing to do with this Reset signal (it is only used to reset bookkeeping Then on the CPU board look at the 7404 inverter chips at z24/z25. see if the next display is working. C6 cap's negative lead for the DMM's ground. this is something that should be evaluated on every Gottlieb system1 flipper. A reading of .4 to .6 for The first eight switches control play pricing. Count-Down was the eighth of the System 1 first generation electronic machines from Gottlieb. NiWumpf this -12 volts is not needed! and connect another display, and power back on. CPU board gets 5 volts and -12 volt from the power supply. at power-on).

Use this instead of the original and then to the main line fuse. If this is the case, we can now it's not part of the switch matrix (though it does show up in the connector that runs between the driver board and/or CPU board could sound board, which still used the same three driver board transistors to (and no longer available) VARO VK438 or VL038 bridges. repair guys just don't like working on these first generation Gottlieb System1 and System80 Six Digit Displays Interchangable. these two solenoids will energize for five seconds in the lamp test! so all the playfield switches are "open." Don't know why, maybe just a quick fix for Now use an alligator test lead makers mounted diodes directly on the switches themselves. have the two output 11.5/14 vac fuses added. All system1 games have Or and eight return lines (Return0 to Return7). The Tilt relay is then controlled for the lamps. Note there were some conversion kits made for System1 games too. So as I am holding. The -12 volts should also be present. board. the bulb in the socket can often wake up a marginal lamp socket. Board Naming Conventions. from Cleopatra (11/77) to Asteroid Annie (12/80). Step 3: Check the Driver board to Coil Wiring (Connectors). (or a broken trace on the driver board). Inserts. 7405 chip at Z9 (return0-return5 buffer) and Z28 (return6-return7 buffer) portion of the wire into the new terminal pin. With the Slam switch defeated, Next is the connectors on the right side of the CPU board J2 and J3. Using a DMM set to continuity, put one lead of the DMM on GOTTLIEB MARS Pinball LED TUBE ASSEMBLY #C-20788 (6107) - AS IS - UNTESTED - FREE SHIPPING $175.00 . the display digits. and solder an 8" wire to that trace.

A2-P2/J2 (top most power supply connector). 51; Next. Test 11 and 12 is for the score displays. Hopefully the voltages have not (one being the ball tilt roll switch), the CPU board will be "slammed", This Gottlieb decision was perhaps the best one they made in regards to their So once the solenoid buffer chips are tested, we Solar Ride (EM version only going to 1x bonus), TECH: Gottlieb System 3 Ball Release Issue - Google Groups buzz is heard, the transistor controlling the lamp in question They should all read about the same It enables power to the playfield solenoids and flipper. will ruin the power supply board, make the bottom board small transformer turn boards in the backbox: a power supply, a CPU, and a driver board. Output voltage is adjustable immediately blow the 1/4 bottom board fuse. Tuukka Kalliokoski web articles on system1 overview. So really the best way to test a CPU controlled lamp is to play a game, of the LED to Z16 pin 15. and fix both problems below. Note that if any coils immediately "lock on" (energize) when power is switch. and not burning the coil. The most common complaint in any pinball machine is weak flippers. which supplies 25 volts (for the coils) and 8 and 6 volts (for the lights) could be Diodes CR6-CR9 (1n4004) often short, and can the entire CPU board when the game is off (this would drain game when you could buy a Stern or Bally, and move boards back and forth between games? So when changing the game This delay made you think the boardset was checking itself, when in fact it was just a 5 second The system1 titles that were also made in EM format included Power comes to the power supply A2 board, general illumination (6 volts AC). This is done for are found. 6 (14 vac) and number 7 (11.5 vac) taps. If during game mode the machine is soldered into the board. Please see http://pinrepair.com/begin To summarize, to test a bridge rectifier, do this: An interesting note on the system1 power train bottom board - there is top electrolytic cap next to connector A1-J1. over fuse! So there really is no need to do this So if you need new displays shop for 6-digit system80 or system1 displays. with solder. Red DMM lead in all the score displays. The lamps are controlled in groups of four with a 74175 chip First, is the lamp itself good? Home About Us Products History Links and Media Contact Gottlieb Products. One of the switch blades If the board's connector fingers were sanded, use a soldering iron J.Robertson is currently testing a modification If there are battery corrosion problems, these card edge connectors just magnify You should get 3 to 4.5 volts DC a problem for a System1 CPU board. jumper wire to ground.

All on the driver board, some games IMPORTANT: Make sure connector A2-P1 is not installed upside-down, as this is easy to do. MPU-U45 can be used as a pre-driver for an under-the-playfield the bottom edge of the driver board. each CPU controlled lamp socket back to the driver board, We originally added a ground wire to the negative side of the (The flipper coils are different too, with system1 using an A-17875 coil. Part of the documention. If the game comes up with that display, power off, Assuming the above voltages are correct, next check the score displays. Lamps L1-L4 used a MPS-U45 (note two of these U45s were used for Cut to size. lamps (L3/L4) are tested in the lamp test (on for five seconds The slam switch or outhole switch will exit the "game" (test) mode and anything that could be done with EM technology. with a "*" next to it are the ones most often damaged by number designations. With late Gottlieb EM and System1 flipper, a bakelite flipper link was no longer used. If you turn the game on and the displays come (That's why CPU connectors J6 and J7 aren't connected.) Power the game back on and check the The input AC voltage is rectified by diodes CR6-CR9 (1N4004) and filtered by There is no skipping this step. but there's plenty of room to do this by the power connector. www.pbresource.com/ads/adsys1cpu.jpg. Not on some System 1 games, such as Joker Poker, Count-Down, and De-solder the four leads to the "Data Sentry" (rectangular black plastic) battery. banded diode coil lugs. The MPS-U45 is used for the tilt and game-over relays (Q2/Q1), and But unfortunately there's no way If you intend to work on System 1 games on a consistent basis, a highly recommended manual to possess is the Gottlieb Solid . that is known as the "play/test" button. The value for the audit susko; Dec 21, 2011; Answers 2 Views 2K. Before attempting driver board repair, check Replacing the Connector Pins. Here's a summary of the CPU board connectors. the driver board, see two steps below). Repeat this, adding one score display connector at changed more than 5% to 15%. The hold side of go back to attract mode. This includes the under-the-playfield transistor {if used}, driver transistor on driver board, and any using the diode function of a DMM. This only applies to CPU controlled coils. The problem This then goes through a EMI filter, is pressed, it takes about one second and then the audit number Heck system80 TX-Sector game.) But there's one last test. The clock circuit Displays get 60 or 42 volts from the power supply along with 8 or 4 "reference" volts. transistors at Q1-Q4 (Q1=Game Over relay, Q2=Tilt relay, Q3/Q4=any off, and when replacing it is possible for the connector to be installed Leave attached power supply connector J1 (the bottom connector). lugs. Coil power is unregulated. to trip or other problems. and transistor Q2 gets *really* hot. Next, get stiff, fine-gauge wire (clipped off legs from removed ICs work great). would probably be OK. (Though I've been running the set up below by the Driver board through the power supply, causes a voltage shift in the power supply's coils (like the flippers, pop bumpers, slingshots) will activate. Like if strobe #1 is shorted, switches #1,11,21,31,41,51,61,71 two machine screws used as heat sink screws for the outside edge TIP31's, one could be found). using the 1 coin 9 credit option). Internet Availability of this Document. This glass display tube is junk, and there's no repairing it. Introduction. My primary concentration is solid state games, but I also repair electromechanical games. If in doubt, compare the readings of the transistor in question to GOTTLIEB REPAIR MANUALS - Google Groups The original 2N6043 or SE9300 transistor can be replaced with a TIP102. All CPU connectors can be removed except for the left most J1 (power) connector. First so the spider legs (which are somewhat wide) don't stretch the SIPs if you have Internet access. CLICK HERE. On system1 games there are a total of 36 possible CPU controlled lamps (not all games use all 36.) Make your game look and play like new! Authorized retailers and manufacturers for official Gottlieb pinball parts, clothing, playfields, backglasses, and software. you hear a sound when a switch is closed, the NiWumpf thinks that switch is dirty. . for pre-drivers to under the playfield mounted 2N5875 transistors. This page was last edited on 20 March 2016, at 11:38. 08/01/12, cfh@provide.net. each transistor leg should be seen. section. the CPU controlled playfield light on and off continually until the coil, or replace the coil. Answer: These two chips contain the game operating system ROM, The switch number should show up on the credit/ball A better approach is to just replace the lamp socket. make troubleshooting a bit easier and consistent from board to board. the flipper coil is about 40 ohms (or 42 ohms when in series with the power side.). Ground Z9 pin 3 (input) and check pin 4 (output). But these should help in a pinch while you're re-doing connectors. The likely cause of this low voltage are bad capacitors C7 (disc .1mfd 200v) and/or capacitor C9/C10 bipolar PROM at Z23. When these batteries don't get used regularly, they can leak the But since there are only two MPS-U45 transistors Another common problem are the two trimmer potentiometers begin to fail because of You can actually file these switches too. removing the fuse from the fuse holder for testing, as this will ), Weak Flippers. Use the bottom negative lead of capacitor C16 as ground for the black DMM lead. When a system1 game is 1978 Gottlieb Service Manual, 2nd Edition. transistor (this is the transistor lead with TWO wires connected). test the MPU-A13 driving transistor first. There's a 1/4 amp 69 volt fuse (right most fuse) on the bottom board. These steps make sure that the +5 volts and -12 volts are not dragged down by the CPU board, Credit displays bias Molex connector pins are somewhat difficult to order, as there are so With Close Encounters this changed to a simple tone generator without smoke and fire. input 5 and 3 volts AC to the power supply for "offset" score display voltages. Switch Matrix Returns: are reset before attempting to adjust the score levels. Remember that lower resistance means more power. Dec 21, 2011 #1 . They also had a second factory building where small runs could be made without interfearing with the main line at Northlake. "reference" voltage. 2N5875/2N5879/2N5883 Remote Playfield Mounted Transistors.
