So the P-ROC is a piece of hardware that simply replaces the existing CPU & Driverboard in a WPC, and allows you to control the playfield with a set of NEW rules that the you define ? However, it is not a direct replacement for an existing board that will run the original code - like an Altek does for Bally/Stern SS machines.

But what I think is really cool is that if you owned an Addams Family, and someone wrote a NEW code for the game - you could simply download that code into your machine (as long as you have a P-ROC in your Addams).

Hope I got this right - This is how I read it and I think it is an awesome development !
