Quoted from applejuice:
The whole purpose of this project is to make a kit for people to upgrade their games so this is my new controller board that will run everything. It’s not just a rom change!
The board will be a direct drop in replacement for the original
So, are you no longer using the P-ROC? Early on, you said you were using a P-ROC plus a system 11 interface board. Does this replace both of those? What are you using for the CPU?
Very impressive work by the way. Whirlwind was the first machine that I played a lot, and I would like to own one again some day.
