Ni-Wumpf Gottlieb System 1 MPU

Out of stock - not available to order
The Ni-Wumpf System 1 MPU board - 2020 revision is a plug-in replacement for the original Gottlieb System 1 CPU. It supports all of the games in the platform series and provides considerable diagnostic capability for the technician when troubleshooting where a game may be malfunctioning. The entire game software has been re-written with an emphasis on maintaining the timing and compatibility of the original board, however with quite a bit more functionality added in: 

  • Direct replacement of the original System1 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!)
  • Eighteen years in business with thousands of boards sold internationally
  • A 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)
  • Power-up code revision and game setting displayed for quick diagnostic configuration identification
  • Enhanced switch test to identify stuck switches
  • 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!)
  • Automatic scoring threshold adjustment
  • Ball Save!
  • Million point-scoring
  • Idle mode animation
  • Skill shot option
  • Four scores memory
  • 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 NVRAM 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 game's operation, including the slam switch!
