Skeeball Rehab

[Bulliesrevival]

I am new here and new to this type of project. I'm going to attempt to upgrade my childhood skeeball machine into something that my children and I can enjoy again. I am a very tinker type person and have 3d printer and vinyl cutter to help this project look great. hoping I can get help with the software side of things.

Short backstory: my dad bought this for my sister and me at an estate sale when I was around 10 years old. As we got older, my dad gave it to my aunt and uncle for my cousins. Fast forward to now, and I (now in my 40s) have gotten it back from my aunt and uncle for myself and my kids.
However, the only thing that actually works is the override button for the ball release. It doesn't keep score anymore, has no sound, and doesn't track the ball count.
I'm trying to figure out how to replace the scoreboard with a monitor and use something like an old PC or laptop to run a digital screen. I've seen many people here have achieved the same and I look forward to any help and input on ways I can accomplish this. Heard that there's a JumpBall program out there that might be what I need but cant seem to find who has it.
