This is my line of replacement display boards for Model H and Model S Skee Ball machines.  I also make an adapter that interfaces my displays to Model 78, Model D, and Model E. These boards replace the original printed circuit boards (PCBs) that used mini-bulbs to display the game score and balls played.  My completely redesigned boards are drop-in replacements for these classic games.  

I have created replacement boards for both the score display and the ball count display:

(1) Skee Score:  This is the score display board.  It uses a micro-controller that is running software I wrote to convert the computer's serial data stream into score digits presented to the game's player.  It easily attaches into existing mounting holes in the game using hardware I provide.  The wiring harness is identical to the original mini-bulb display board so you can simply unplug the old one from your machine's computer and plug in Skee Score replacement... super easy!

(2) Skee Ball-Count:  This is the ball count display board.  It also uses a micro-controller running software I wrote to convert the incoming serial data stream presented to the game's player.  Simply plug directly to the Skee Score display board.  The Classic Display Set includes a replacement ball-count baffle that easily installs on the existing mounting studs as a unit.  The Modern Display's ball count mates directly to the Skee Score board... simplicity is good!

Whether you choose the Classic or Modern Display is simply personal preference - each is a "better than original" solution... awesome!

This is everything you need to replace the displays in your  Skee Ball Machine and retain the classic display look - the Classic Display set includes:

Classic Skee Score: The score display board that fits directly on the back of the original display baffle and plugs directly in to your model H or model S computer.  

Banana Mounting Pegs: Easily attach your Skee Score into existing mounting holes on your original baffle 

Classic Skee Ball-Count and Skee Ball-Count Baffle: The ball count display set pre-assembled and ready to install on the existing mounting pegs in your machine.

This is everything you need to replace the displays in your model H or Model S Skee Ball Machine with the modern display look - the set includes:  

Modern Skee Score: The score display board that fit directly on the original display PCB mounts and plugs directly in to your model H or model S computer.  

Replacement Mounting Pegs: The originals are likely brittle from exposure to incandescent lamp heat, so I include replacements to facilitate your installation. 

Modern Skee Ball-Count: The ball count display attaches directly to the Modern Skee Score via a board-to-board header connector.

Model 78/D/E Adapter

The older Skee Ball models implemented more basic display driving technology that is not directly compatible with the relatively newer model H & S displays.  I have created an adapter that converts the older display signals to the format used in the H&S games.  The adapter connects directly to the score and ball count plugs on the 78/D/E computer and as shown below can directly drive either my Classic or Modern displays:
Some technical details - My redesigned boards use today's technologies to recreate the look and feel of the original parts. For example, my boards are micro-controller driven so they are not using the out-of-production electronic components that were used to build the originals. I wrote the software for the micro-controller instructing it to perform the conversion of the Skee computer's data stream into the 7 segment displays. I've incorporated high quality LEDs into my designs to eliminate the fragile lamp sockets on the originals and to forever solve the problem of replacing the incandescent lamps. This also eliminates the heat from the bulbs that over time ruin the plastic baffles.

Replacement MTN4123 Digit for Skee Ball Extreme displays  - A self-assembly kit to Repair classic arcade displays!

  

The 7-segment module (part # MTN4123-AHR-A) used in Skee Ball Extreme displays is no longer manufactured.  My replacement is a single digit 2.3 inch 7-segment display module that is the exact width and height of the original MTN4123-AHR module.  It uses the same 10-pin pinout of the original modules.  My multi-layer manufacturing process is easy to assemble as a kit and creates a pleasing viewing that resembles the glow of the original part.  Soldering skills are needed to remove the original MTN4123 from the Extreme display PCB and to install this replacement. Please order 4 if you intend to replace all digits on your display board.  Instructions for kit assembly are in Google Docs.
