The Premier Stern MPU-100 Hybrid MPU Board (H.T.E-3)

This MPU-100 board supports all 12 Stern MPU-100 games on one board.

Bring your classic pinball machine into the modern era with this full sized replacement MPU. 
These new Hybrid MPU boards are based on the final,
most refined version of the factory Bally Cybernaut system utilizing the robust 6802 CPU with a precision crystal clock.
While the system still runs the exact same faithful logic architecture as the original factory design, 
the hardware has been significantly improved. 
Every single legacy flaw has been meticulously engineered out for bulletproof reliability:

High-Speed TTL Logic Upgrade:
Out with the slow, glitchy CMOS gates! Upgraded to high-speed TTL logic for faster, rock-solid, glitch-free gameplay. 
Even under the fastest, highest-speed game play scenarios, this system will never glitch out or lock up trying to keep pace with your scoring.

True Onboard NVRAM: 
Built-in NVRAM permanently saves and protects your high scores and bookkeeping data. 
No batteries, no capacitors, and zero risk of battery acid corrosion ever again.

Proprietary High-Voltage Optical Isolation: 
Unlike factory boards or basic replicas that expose delicate logic chips to cabinet voltage, 
our design utilizes an exclusive optical gap isolation barrier on the 43V solenoid line. 
If a playfield coil shorts out or spikes, 
the dangerous high voltage is physically blocked from reaching your 5V logic circuit 
safeguarding your board from catastrophic damage.

Advanced Single-Chip Precision Power Supervisor: 
We have completely eliminated the troublesome, drift-prone 15-component factory reset circuit. 
In its place is a premium, dedicated single-chip Silicon Power Monitor 
paired with a small Red LED to show instantly when it is activated, 
guaranteeing a perfectly timed, clean boot every single time you flick the switch.

Top-Right Tactile Control Buttons:
Three full-sized buttons are conveniently located in the top right corner. 
Features the original factory Memory Clear, but now thoughtfully updated with an onboard Self Test and Reset. 
No more needing to turn the machine off/on just to re-boot after making bookkeeping or game adjustments!

Technical Specs & Machine Compatibility:
Designed to perfectly suit the early Stern MPU-100 system 
this version of my board will support 16 games, being the full 12 Stern titles & 4 popular Bally

Note:- this board is sold with a Blank EPROM
But wait theres more !
🔧 Free Setup & Testing:- Message me after purchase with your pinball game title. 
I will provide a complimentary service to load the ROMs and fully test your new board with your requested game title before shipping. 
This ensures you receive a 100% plug-and-play MPU board.
