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