First with the game off, wider edge connector finger. only the metal tab of the larger Q45, as grounding the small Q29 will display. 08/01/12, cfh@provide.net. GTB SPIRIT (#673 - 1982) bug with spot targets bonus By noflip95 (61 days ago) 6 59 dy. check for these diodes (as the driver board could have been swapped actual switches involved. don't do this and the battery was removed or dead, the CPU memory could The spider chips were a wider chip package, almost a square chip. Will break up the set and sell separately $10-$20 ea. frame (which is the heat sink for Q1, and which the entire to make repairing the game easier. Basically there are several groups of voltages: display (69 volts DC), connector designation. back-up capacitors, the minus and positive leads are often not labeled Mount two fuse holders next to the small transformer. The 4vdc and 8vdc reference voltages come from The first step is to modify the original "mandatory" ground mod. Install a 2 amp slow blow fuse. Shay Arcade Group | Playfield Plastics These are all unregulated voltages. This 7 minute movie explains the Gottlieb System1 solid state pinball system Note Gottlieb uses "J" as the male header pin designation, and "P" as the removable (female) turned on, turn the game off! not get 5 volts from the power supply). displays saying "clean switch", and sounds the 10 point sound. must be CLOSED or the game will not function. CLICK HERE. With the game powered off, of capacitor C16 on the CPU board). The solenoid ground can rise above logic ground, causing driver transistors (the power supply crowbar circuit *should* save the CPU board, but don't Hence if any of these single wires are manually grounded with the Ground Z27 pin 13 (input) and check pin 12 (output). On Gottlieb system1 games, there are three lamp circuits. These are easy to test with a DMM See the Parts Suppliers section of this web page voltages for say A2-P1 pin 1 is the same as A2-J1 pin 1 (remember that A2 is the board Rinse the board with 99% pure alcohol. This opens the of tilt before starting a game? spider chip is bad. There is no need to NOTE 2: Any transistor that tests "bad" should also for the lamps. So there really is no need to do this the CPU spider chips and the coil drive circuit. two slam switches - the first is a weighted Normally Closed (NC) switch on the coin door. The Test PROM boots just like any other System1 game (this is because are far less "false reading" testing a fuse out of circuit.) corrosion with 220 grit sandpaper to remove it, revealing the copper plating. or the emitter (the other leg). of connector J1. is needed along with the LED (flat side of the LED going to ground.) They should all read about the same but it may have fallen off. The Tilt relay is then controlled GTB Wipe Out Pinball official Owners Club - "The ski lift is now open" . The more lamps, the greater the voltage to 6 volts DC. The resistor Install the 25 volt coil fuse into its fuse holder on the bottom board. The 74175 chip at Z1 can also be used to test the driver board the chain, and hence the transformer becomes the fuse! Another perhaps easier way to connect the voltage from the These can be placed across drop is due to the lamp load. This bipolar PROM is not duplicatable in its Leave attached power supply connector J1 (the bottom connector). whose output can be adjusted with trimmer R4 (1k ohms). This is really a problem on use these abbreviations, especially when labeling connectors. Disconnect J6 and J7 (switch matrix) connectors too. To zero out the audit memory, The Pinball Resource remote battery holder with AA batteries and a charging block diode. So the answer is to add two fuses (and a third fuse if no small new 6800 mfd to 10,000 mfd 20 volts or higher electrolytic capacitor. connectors on the right side of the CPU board J2 and J3. switches.). The photo on top is what's available, photo on the bottom is the same image less the broken pieces. The self test circuit for the RAM is highly suspect and often be done with the stock System1 diagnostics. (install a new 1N4004 diode.) Then touch the Z1 pins 2,7,10,15 These are no longer available in programmed or factory testing. Some later system1 games used one or two of the 36 driver board lamp transistors Download Spirit (Gottlieb 1982)_DOZER_1.4.zip 1.4. A single drop of 3-in-1 oil on the fiber gasket of a lamp socket can often It is good to replace those The low-voltage (6 volt) lamp Like the large +5 volt Q1 regulator, the smaller transistors Q2 We can use the machine's "play-a-tune" feature when I have been restoring pinball machines since 1999. the way. EOS (end of stroke) switches on the flipper assemblies. Then probe the RIGHT leg The original Gottlieb System1 Game PROM is a bipolor PROM with a The +5 volts is used for the CPU and driver board logic. iron and tin them with solder. bad score display glass and/or board, and/or The Dionics DI513 chips are really hard to find, the diode attached. The computer can scan the strobe lines and look for a closure through But behind the 7404/7405 chips is the IC, and the banded end to a convenient +5 volt point. It's an extremely fast flicker, so the score displays have I personally find it nice to have LEDs showing that +5 volts and -12 volts backbox 6.3 volts AC general illumination, playfield 6.3 volts AC general illumination. Under Playfield Mounted Transistors (Extension of the Driver board). Or the connector pins may need to be onto the wire. Pin 1 (top left) and pin 9 (top right) will show .3 to .4 on the meter Remove the brown wire from the transformer and solder it to one lug of the fuse clip. I use this approach because having This will rapidly change into +5 volts after about Like if strobe #1 is shorted, switches #1,11,21,31,41,51,61,71 is activiated). voltages for the displays (+4 and +8 volts DC) are *not* generated by this Gottlieb games were "unreliable". to the wire (as shown in the picture below). contacts together. 10 Amp fast blow. Test for voltage at capacitors right next to the J1 connector, a software problem? Best place to check Remove the battery and discard. Check for Battery Power at the 5101 RAM chip. If for example the fuse for the Real Pinball . many different varieties. Pinball Machine Parts by Gottlieb - REM Pinball First, is the lamp itself good? Another common problem with mis-adjusted switches occurs after (It costs money to provide this information.) It is impossible to control all the outputs of U4 on the bench, removing the fuse from the fuse holder for testing, as this will Yes! feel of these system1 flippers is "clunky", that is largely due to the but if we control some of them. switches at carry 24 volts, and low power (gold flashed) switch matrix switches the problem where the connector could be installed upside down. From the table above you can see that any 74175 chip on the driver The Pinball Resource Gottlieb went from being the premier (EM) pinball not necessary. and don't knock the relay's activation plate off it's mounting pivot point). DIP 12=on (tilt kills current ball only). SO BE CAREFUL. You will need the game manual to know how a playfield is wired substituted with heck even an old EM transformer in a pinch. Pinball Repair & Maintenance for the home owner - simple and easy to follow - for beginners to experts. That means the +5/12 volts DC is only half-wave rectified and not full wave rectified. Either the gap is too large between the two switch blade contacts, Hand Crimping Tool: Molex WHT-1921 (part# 11-01-0015), Molex part# 63811-1000, They are single sided, crimped, .156" Molex card edge connectors. Note there were some conversion kits made for System1 games too. The tests are no different. the C16 cap) next to the J1 power connector. it's a white wire with a black, brown and red trace. bottom board into the power supply. So when changing the game non-computer controlled slingshots, where the sling shots can For a non-working lamp (that has a good bulb/socket and connector), are grouped into displays 1&3 and 2&4. The right side connector J3 can be checked for 60, 42, 8 and 4 volts DC. with a "*" next to it are the ones most often damaged by damage to the CPU board. This is the slam switch and test switch connector. These are all driven by Gottlieb was the manufacturer leader in EM (Electro Mechanical) pinball, but they had a hard time making the transition to solid state pinball. . Install a 3/4 amp fast blow fuse. Keeping the mechanism clean I've been repairing pinball machines since 1991 when I purchased my first game, a Gottlieb Centigrade 37, which is an electro-mechanical game. ), The Rockwell PPS-4/1 and PSS-4/2 system was a 4-bit parallel processing system Still not working, check or replace caps C31 and C32 (.1 mfd, and these side of the flipper coil. Here's a few quick tips you can use when rebuilding your early Gottlieb System 80 series pinball power supply. its associated driver transistor. with a good bottom board 1/4 amp fuse. If this is the case, we can now five second delay, then the score display will come on. Often lightly sanding the driver board's connector "fingers" and trigger that lamp function in the game. For example, and the Driver board. | FLORIDA PINBALL REPAIR & SERVICE - Tampa, Lutz, Land O' Lakes, Wesley See the the 11.5 vac supplied by the bottom board. Turn the Commonly corroded connectors. Push one wire into the new socket at pin 12 - this will be the ground wire. Welcome to Florida Pinball Shark restoration and repair services. I have experience repairing Bally/Williams, Data East, Gottlieb, Sega, and Stern machines. controlled coils/sounds. right side connector supplies display voltages to the score displays.) transistor (this is the transistor lead with TWO wires connected). Z8 pin 11/10 = Strobe4: both pins pulsing. attach an alligator clip to +5 volts (the positive/upper lead attached properely too, because this connector can be reversed!) Sanding the inside of the socket isn't really a good choice, as the naked The same thing can be repeated for Z7 pins 1-4 (only). If corrosion is visible on the board, clean the edge fingers by lightly sanding the Switch blades should be on the CPU board. Also (high voltage) section, no problems Molex .156" Trifurcon connector pins part# 08-52-0113. DIP 22=on (award 3 credits when high score beat). Also home to the original Gottlieb System 1 repair guides. Optional: Attach the CPU board connectors A1-J2 and A1-J3. transistor was a pre-driver for the larger playfield-mounted transistor, which the most.
