GOTTLIEB SYSTEM 1 CPU BOARD                   $350.00


The System 1 Board 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:

BENEFITS: 

➡️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!)

➡️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 configured 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.

➡️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 threshold calculation and adjustment.

🔘Tournament mode - Special award replaced with points

🔘Operator set Ball Save time!

🔘Million point scores shown in scrolling display.

🔘Idle mode animation.

🔘Skill shot option.

🔘Four high score memory.

🔘Restore factory-settings option for quick reset of settings.

🔘Wizard mode for some games

➡️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!
