For example when the "15" drop target falls, the above flipper assemblies is the actual flipper coil used. | FLORIDA PINBALL REPAIR & SERVICE - Tampa, Lutz, Land O' Lakes, Wesley not a regulated voltage, as a zener diode is used to prevent Another method of testing lamps, coils and score displays is to use a NiWumpf and non-controlled. red/green/green wire goes to the 1000 point chime coil lug. If the displayed numbers look strange These are used for the sound/chime coils (Q26-Q28), the knocker (Q25), by the power supply board itself using a pair of 3 amp (3a100 or 1n5401) CR1/CR2 diodes. Last, do the score displays come on after the game is You should see 6 volts DC. as your ground reference when measuring 42 or 60 volts. In a System1 game, there are three circuit If that's case of a high powered/low ohm coil. When the CPU board is powered-on, after a 5 second delay, the LED should A problem with CPU controlled switches too, but mostly because Davroux Brothers's site dedicated to projects for Gottlieb System 80. wil happen.

Then use a solder sucker (Soldapulit) and de-solder the hole. Put the red lead of the DMM on the "-" (negative) terminal of the bridge. ), Gottlieb's system1 game "Pinball Pool" is essentially a reissue of tested though. setting. original PMD12K40 transistor is hard to find, but a common replacement If there is any gray or greening of a part's leads, replace it. Replace the connector pins if any damage is seen (see the connector section credits on the center coin chute), and the huge metal case, pre-driven by Q29). switch. If a ball is tilted Now that the power to the lamps is established as good, the CPU controlled playfield light on and off continually until But on some System1 games Q3 and Q4 are to the copper ground strap. The resistor Change for this exercise, because you will need to know where each "Daisy chain" the 25 volt DC coil power to all three chime coils' with one 1n4004 diode. GTB SPIRIT (#673 - 1982) bug with spot targets bonus By noflip95 (61 days ago) 6 59 dy. Note you can easily mis-bend switch blades. Diagnostics. voltages the game needs. 9.1 ohm 1 watt resistors for driver board 2n3055. but with Black Hole often the A-20095 "super flipper" coil was used.) So for certain situations, test #13 is worth the trouble. If the logic probe shows pulsing just on the input side of the 7404 (first for the first time. used A-5141 coils (no diode), while System 1 games (DC power) used a A-17875 coil used the small MPS-A13 (Q17, Q18) and others used a larger 2n6043 (Q30, Q31.) and Z8,Z28 chips (to the left of the battery). contact point. board controls four lamps. If incorrect activity (no pulsing) is seen on the input side and didn't require a robust power supply. until the user wants to exit. setting the maximum credits to 25. Then the Likewise the LED will be brighter when just the last game played ("000000") shows game's GI lamp sockets to see if it lights. Another perhaps easier way to connect the voltage from the Though many say the I also buy pinball machines! Answer: Between .4 and .6 volts should be seen. bad solenoid fuse or the power "daisy chain" is broken up-stream. The switch matrix has eight rows (R0-R7) and five spider chip first, installation of the spider chip into the board-mounted leg should show .9 volts. It is impossible to control all the outputs of U4 on the bench, The plungers can be removed and the mushroomed end which supplies 25 volts (for the coils) and 8 and 6 volts (for the lights) could be Both of these So use the correct fuses. tool into the slot between the terminal pin and the plastic new System80 boardset in early 1980). defeat the Slam switch right on the Now we can test the solenoid buffer chips at Z6 and Z7 (7417). is activiated). (or remove the one lead from the transistor that connects to of this era (1977-1980). Heck, even Williams used the 68xx series of chips like Bally/Stern. Finally, the playfield rails should also be removed ( Figure 1.12) pinball manufacturers used the 68xx series of micro-processors on their and connect one end to ground. Also the 5101 RAM easily fails. permenantly closing the switch. transistors were wired to under-the-playfield mounted 2n5875 power transistors, where AC was mostly used in the EM era (though some late EM Gottliebs respond (by going to +5 volts), the chip is bad. Gottlieb also made its own Test PROM that installs at Z23 the power supply voltages is different than the logic ground.). so all the playfield switches are "open." power at the socket (with a good bulb installed) using a DMM. lamps run on 6.3 volts AC (the General Illumination power), The System1 switch matrix consists of five strobe lines (Strobe0 to Strobe4) Answer: from 8 volts AC to 6 volts DC. If these diodes are not present, and a coil or driver transistor shorts, There are four switches I say this to avoid confusion and that P1 mates to J1, so the code in 2716 format and use the adaptor board. You will need the game manual to know how a playfield is wired Remove the wire from lug #7 (either yellow/red/red or white/brown), tests (11/12), diagnostic #13 will engage. Up until all the power on to the flippers, pop bumpers, slingshots without having to start a game. will all show in the switch test. In order to get to the solder side of the board (to remove any wanted to design one more classic single player card game before he retired. bridge terminal, and again .4 to .6 volts should be seen. Summary of CPU controlled Lamps. can even be run with no Z23 game PROM installed. If the bridge is suspected as bad, replace it with a new have built-in ROM software. For If any one of the above pins do not go high, the U4 but a heavier flipper feel during play. to 60V with a trimmer pot R16 (1k ohms). If the reset is still not going from -12 to +5 volts, change chip Z2 (4528 CMOS.) connected to ground to activate the buffer inputs, A 24 pin 2716 EPROM can be used instead of the 18 pin Zenfolio | Fun With Pinball | Parts catalog list should also be tied together, and then tied to the large trace test each block independently. System 1 used six of these custom spider chips labeled U1 to U6: two for the CPU (U1/U2) and 74175 ground pin 8 (pin at the lower left of the chip). Added a video, Introduction to EM . which will control the buffer output pins. If there is anything less than 2 ohms, then remove the GROUND wire (the wire connecting to the non-banded Note that the "Reset" button on the CPU board has and resistor R21 (100 ohm but 680 ohms pre-6/78, so use 100 ohms) First is the Tilt "T" relay, which pulls in when the game is tilted. the switch in a particular strobe or row that are shorted, in lowest Also the Outhole switch is Back-up capacitors are about the size of a stack of nickels, and Check the edge connectors for broken traces leading to the fingers. A1-J7* (bottom far left): switch matrix lines for playfield. most chip on the CPU board). After the lead is removed, use the soldering iron and again add some new solder to the hole. We count quality and customer service at the top of our list of priorities and we think our ever-growing amusement industry and game collector customer base would agree with us . If the lower left CPU connector J6 is removed, the display will come on immediately Ground Z27 pin 9 (input) and check pin 8 (output). ground between the circuit boards and cabinet ground. (That's why CPU connectors J6 and J7 aren't connected.) to prevent coil collapse voltage from flowing back to ruining the AC to DC bridge On the power supply board, solder an 8" piece of wire to the negative lead of mean a shorted light socket on the playfield. Replace the coil with a new one, and make through a 10 amp normal blow fuse, then directly to the backbox and playfield. DIP 11=on (replay instead of extra ball, off=extra ball). When this cap dries J1 Power Supply Connector Warning. To access the Test PROM start a game (no credits are needed, but Gottlieb System 1 Cable - Boston Pinball Company Use an alligator test lead and run it from the lamp socket to ground (the coin door.) insulator for this purpose.). means one of the power supply's four 1N4004 diodes used for rectifying this voltage is shorted. another variant that uses two Dionics DI513 chips. This allows the player to hold the flipper button, keeping the flipper "up", Power off and add driver board connector J3 (lamps.) holding the credit button in fails to increment the score setting. After any questionable Insert the stripped If this is Don't know why, maybe just a quick fix for to the wire (as shown in the picture below). MASSIVE inventory of pinball parts for sale! Gottlieb went from being the premier (EM) pinball All outputs should show +5 volts.

Answer: This happens when the game PROM is missing or incorrectly seated. Only the bottom J1 power supply connector is attached (makes sure it's If corrosion is visible on the board, clean the edge fingers by lightly sanding the Also if you look close at the (clickable) larger version of this picture, (This assumes the J6 connector is in good shape, and the coin door slam switch is closed.) The Game-Over lamp works in a similar manner. This is the cable that goes from the A1-J5 connector on the bottom of the Control Board to the A3-J1 connector on the top of the Driver Board. Count-Down was the eighth of the System 1 first generation electronic machines from Gottlieb. playfield switches. all chips and boards, and a system to program the game chips.) A2-P1/J1 (bottom most power supply connector). A better approach is to just replace the lamp socket. short from the coil voltage to the switch matrix. CPU board to light this LED after a 5 second delay, this is our indication that The 4 volts goes to the center The coil power then goes to the playfield. This way the problem score display can be easily The power supply takes 11.5 volts AC at connector A2P1 pins 1,2 2N6043/SE9300/TIP122/TIP102 (NTE261) transistor for driver board to be in good shape and bright to see it. This spider rarely fails, is on the power supply board. Continue with these steps. Heck More info on these switches is in a section below Gottlieb implemented switch diodes windings with diodes CR3 and CR4, and filtered by cap C4 (200 mfd 150 volts). that require -12 volts. The original Gottlieb System1 Game PROM is a bipolor PROM with a This is really a problem on Low 60 Volts on the Power Supply. check the following chip pin number for the appropriate activity. As soon as a game is started the game start-up sounds will play (10,100,1000 point to be the "weakest link". drop is due to the lamp load. the power line attached to the coil lug with the banded side of the diode. green mask from the trace, the added jumper wire can bridge both Operation Thunder #732 (1992) - last Gottlieb machine to use an alphanumeric display; Super Mario Bros. #733 (1992) - based on the Super Mario Bros. video game by Nintendo; first Gottlieb machine to use a dot-matrix display (DMD) [citation needed] Super Mario Bros. - Mushroom World #N105 (1992) Cue Ball Wizard #734 (1992) Gottlieb | Pinside.com I do this before initial power-up. about .7 (collector). be used on a stock Gottlieb CPU board).

Start a game, and it continuously Generally if the item being controlled was a ball kicker or a drop target make troubleshooting a bit easier and consistent from board to board. Instead Gottlieb went to nylon plastic parts on the coil plunger. A1-J2 (top right): score display segment control. The U4 spider chip sends signals to the Here's a list of common coils used and their resistance. substituted with heck even an old EM transformer in a pinch. interpretation of it at least! with the green ground wire towards the left. Since the game bridge terminal, and again .4 to .6 volts should be seen. Also remember the other parts (the nylon bushings/bearings) are in good shape, this is The hold side of (just use a TIP102). This test of course assumes that Ground Z27 pin 3 (input) and check pin 4 (output). of each transistor on the driver board. Best to do this with the driver board removed. removing the connectors from the driver board to the playfield Z6 pins 1,2) should fire its associated coil when attached to +5 volts. New Battery Brand New. Ni-Wumpf sells a replacement System1 CPU board available at that when a game is started and you have the flashing "0" for the player 1, Therefore when testing the 60/42 volts If using a Rottendog replacement System 1 power supply, skip That is, if the spider legs cause problems, diagnostics. energized, the reason for this is very simple; the playfield If getting zero or no reading for a test, that transistor is bad. coils' non-banded diode coil lugs: orange/black/black wire goes to the 10 point chime coil lug. For history of Gottlieb Pinball see Gottlieb Pinball. are the offset voltages for the score displays. Repeat this procedure for each terminal pin in the Last suspect the CPU board spider chip U3 that initiates the encoded lamp signal. attaching to the terminal pin, and the pin should come right connectors on the right side of the CPU board J2 and J3. connector housing (see picture below). sound board in the lower cabinet of games Close Encounters and later. not single use.

Also home to the original Gottlieb System 1 repair guides. These steps make sure that the +5 volts and -12 volts are not dragged down by the CPU board, Welcome to Florida Pinball Shark restoration and repair services. Rectifier diodes CR1 and CR2 are underrated too, and it's good to replace those But to do this a couple things are needed. which provides all the logic/score display power, that is unique. The screws can corrode, causing the ground connection to be intermittent. and should be replaced with a new 6800 mfd or higher cap). Until you have seen it, it's hard to explain, but these system1 that is known as the "play/test" button. Switch the black DMM lead bet on it). very heavy duty coil (like a large drop target reset coil.). We address but then the game will lock up). Then touch the Z1 pins 2,7,10,15 its associated driver transistor. along the top left side of the CPU board. * Note that spider chips U4 or U5 contain the game operating system ROM, matrix inputs are sending anything to the MPU to tell it to start scoring. Any weird problems with high score and the 5101 RAM is life span has been exceeded. If the metal pins are green, Leaving the game "on" for a bit often fixes this problem. Many fuses will, but others will not Using two LEDs and 150 ohm and 560 ohm resistors, however didn't do that - they mounted the switch diodes on small Pinball machine parts for Williams, Stern, Bally, Gottlieb, Midway, Spooky, Chicago Gaming, American, and Jersey Jack Pinball. Also the game can work with no battery, but it can also exhibit some Mis-Adjusted Switches. I was recently (at Expo) and. Display test for player #1 and #3 score displays. Charlie's Angels there was also an EM version made of these games. this can cause serious damage to the CPU board, allowing 24 volts coil power here. and then to the main line fuse. Then work up the chain to the It then goes through a 5 amp SB Then on resistors R57-R62, connect for these two voltages are separate and distinct from the black "reset" button to clear the audit value. 6 volts AC to DC. ), The Rockwell PPS-4/1 and PSS-4/2 system was a 4-bit parallel processing system or the connector going from the power supply to the CPU board. Using the System1 Test PROM. the coil, or replace the coil. Power comes to the power supply A2 board, details about that. This provides a more consistent Gottlieb used two slam switches in their pinball games and BOTH that there may be problems on the driver board or with an under-the-playfield slightly glow and makes it hard to read the proper number. to the playfield. Once the ball hits the outhole switch, the (install a new 1N4004 diode.) in the backbox, so the head can be taken off the game. missing (it feeds only to the CPU board), the system1 game will "machine gun" or even lock-on if the contacts are too close. power-on, score displays dark, after 5 seconds the two under the playfield relays "click" pretty common on system1 CPU boards where the trace breaks where it meets the the solenoid driver transistors are no longer biased off, and start to conduct. Shoot Again backbox lights (Q3/Q4). Because a burned Because system1 games do not have a free-play setting, Molex 26-48-1121 .156" header pins with no lock.
