Gottlieb System 1 Ni-Wumpf CPU


$195.00


Gottlieb System 1 "Mark II" top quality Ni-Wumpf CPU board.  Here are a few benefits about this board compared to the original:

- Direct replacement of the original System 1 board.

- Enhanced switch input circuitry preventing damage to the board from playfield wiring issues.

- 3-month warranty.

- All game code completely re-written (with some minor original Gottlieb glitches omitted!)

- Text based diagnostics menu system that allows operator settings previously done via DIP switches to be entered via front door switches.

- Tests that cycle repeatedly (until timeout) to help isolate faults.

- Enhanced use of high reliability surface-mount components with off-the-shelf thru-hole components at the edge for ease of serviceability.

- Display test to exercise all digit segments (numbers), and to strobe each digit independently to check for display (UDN6118) shorts.

- Solenoid test that exercises each coil including lamp controlled coils (when DIP switch configuration set for such a game).

- Enhanced switch test to identify stuck switches.

- Power-up code revision and game setting displayed for quick diagnostic configuration identification.

- Switch test that detects dirty switches on the playfield.

- All 16 System 1 games are included on one board with no ROM swapping required.

- One DIP switch setting to select your game.

- Original MPU functionality has been closely duplicated and adds many optional features including:

Free game mode, Updated game options for many games to allow add-a-ball mode (multiple free-balls awarded during a single ball) where the playfield challenge is completely reset once after scoring the free-ball / special, Menu options to disable add-a-ball (for operators who requested it!), Restore factory-settings option for quick reset of settings.

- Open-collector output logic with zener diode protection for all solenoid circuits and lamp select lines to prevent CPU damage from a damaged driver board.

- Battery-less operation; all settings and high-score data are stored in FLASH with >100,000 write cycles.

- Designed for low-cost component repair and maintenance on I/O sensitive components (exposed to bad displays / bad driver boards, etc.)

- Stuck switches are ignored and do not impair the rest of the games operation, including the slam switch!

Asteroid Annie, Buck Rogers, Charlie's Angels, Cleopatra, Close Encounters of the Third Kind, Count Down, Dragon, Genie, Hulk, Joker Poker, Pinball Pool, Roller Disco, Sinbad, Solar Ride, Torch and Totem.
