Ni Wumpf Gottlieb Sys. 1 MARK II CPU Board

Gottlieb® System 1 CPU Board - Ni Wumpf MARK II model

New MARK II design, plug and play replacement for those
unreliable, unobtainable, un-repairable old Gottlieb System 1
pinball machine main computer boards.

The wizards at Ni-Wumpf (an inside joke for Monty Python
aficionados) created this new, half size computer.

This new MARK II board is a plug-in replacement and upgrade for
the original GOTTLEIB System 1 CPU board. 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:

Key Benefits:

• Direct replacement of the original System1 board.
  
• Enhanced switch input circuitry prevents damage to the
  board from playfield wiring issues.
  
• All game code completely re-written (with some minor original
  Gottlieb® glitches omitted!)
  
• Text based diagnostics menu system allows operator
  settings (previously set via DIP switches) to be entered via front
  door switches.
  
• Tests 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 exercises each coil including lamp
  controlled coils (when DIP switch configuration set for such a
  game)
  
• Enhanced switch test identifies stuck switches.
  
• Power-up code revision and game setting displayed for quick
  diagnostic configuration identification. Switch test detects
  dirty switches on the playfield.
  
• All 16 System 1 games are included on one board with no ROM
  swapping required.
  
• Original MPU functions have been closely duplicated and
  many new features added 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 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 high 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 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 game operation, including the slam switch!
