OK, this is awesome!

Quoted from pinwiki.com, https://www.pinwiki.com/wiki/index.php?title=ALI/Fascination_Repair#Introduction

4.3.2 Generation 2, All generation 2 solid-state ALI / Fascination games use the exact same MPU board and software; game "rules" are changed simply by rearranging the placement of switches, targets, lamps, pop bumpers, and other elements on the playfield.

So your modification could potentially bring back all these games and possibly others where the custom IC's are NLA:

Take Five
Flame of Athens
Hearts Spades
Disco '79
Star Shooter
Circa 1933 (Fascination Int.)
Eros II (Fascination Int.)
Eros One (Fascination Int.)
Roy Clark The Entertainer (Fascination Int.)

You could clean up the installation a bit by making or buying cables that use something like the DuPont type male-male connectors and they are relatively cheap.

+1 on Github. Really easy to use and free. Its a great place to find code for about anything you can imagine.

If you want to see an example you can check out my Black Hole disc blinker/motor controller board there:

https://github.com/KenH2000/BlackHoleDiscBlink

You could post your entire project there, with photos, videos, assembly instructions, code and so on.

I feel like something should be added to the pinwiki in the Allied Leisure section. This is potentially the only way to revive these games if the 6530's are dead.
