These have exploded diagrams of assemblies, particularly in earlier games that had the thinner, much less helpful manuals. Gottlieb tended to publish a lot of game-specific information in parts catalogs. Parts catalogs can also be useful, which include part numbers (helpful for purchasing parts online), exploded views of assemblies (helpful to see how the assemblies are put together), and board layouts & schematics, and diagrams for controlled lamp, solenoid, and rubber locations. Pinball Resource has many factory originals still left, and reprints of everything else. Uses an MA-2178 display board for driving two DMDs instead of MA-1739Ī game manual. 8 positions of 1N4148 diodes are replaced with 1N4008 diodes for # 86 lamps MA-1294 C12 is marked C12 & wire jumpers used MA-1033 C12 is marked R5 & zero ohm jumpers used Gottlieb® System 3 Board Set - Dot Matrix DisplayĢ Game Listing 2.1 Alpha-Numeric Game Title Gottlieb shrunk its two-spring drop target into a one-spring version with a smaller footprint, but that didn't play as well.The nigh indestructible "fat boy" flipper was changed over for a new +50V pointy flipper that actually malfunctions.+5V power supply essentially unchanged from 80BĪdditionally, several common assemblies were redesigned:.Under-playfield open-frame relays for control of flippers and general illumination remain.Ground problems remain, although they have been improved.A lamp matrix that can drive 96 lamps, nearly doubling the number of CPU-controlled lamps.The battery is lithium coin cell, and rarely leaks!.Under playfield step-up transistors are gone! The system supports 32 solenoids directly, an increase over the quaint 9 of System 80.No more high voltage switches all over the playfield. Solenoids are now universally solid-state controlled (except the flippers).Finally, they resolved most of the issues that had been plaguing the electronics for their games for years. 7.1 Mixed-Up 6-pin Power Supply & Driver Board ConnectorsĪfter many years of suffering with System 80, Gottlieb launched its System 3.5.12.2.5 Vertical Solid Bands Displayed on DMD.5.12.2.4 Vertical Solid Lines Displayed on DMD.5.12.2.3 DMD Freezes After Entering Attract Mode.5.11.5 No Switch Matrix or CPU Controlled Lamps.5.11.1 Conventional (Leaf and Microswitch) Switch Problems.5.10.2 No CPU Controlled Lamps or Switch Matrix.5.9.2 The Bottom Connectors on the Driver Board.5.7.6 Other Boot Issues - Stuck Address/Data Lines.5.7.3 System 3 Low Battery Boot Message.5.7.1 Relocating the battery from the MPU board.5.6.2 Using a Power Supply For Bench Testing.5.6.1 Connecting a logic probe to the MPU.4.16 Accessing Bookkeeping, Settings, and Test Modes.4.13.3 Dot Matrix Display Controller Board.4.4 Connectors and Connector Designations.
