NI-WUMPF MARK II Gottlieb Sys. 1 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.
