Gottlieb System 1 - Ni-Wumpf MPU Mk-2
Model: Ni-Wumpf-Sys1
 $199.00USD 

Description

The new (2014 design) Ni-Wumpf System 1 board MKII 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:

Key Benefits

  • Download the manual here!
  • 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!)
  • Eighten years in business with thousands of boards sold internationally.
  • 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.
  • 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 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 the rest of the games operation, including the slam switch!

(Oct 20, 2018) There will be a series of rotating postal strikes in Canada starting Monday Oct 22, so parcel items may not be picked up for a day or two - in other words, there may be delays. Currently Vancouver/Burnaby are not scheduled for strike action, so the mail will continue for now. We shall keep you informed as soon as we find out more.. We do offer FEDEX shipping for our customers as an alternative.
