Author of that program was
tl;dr: Answer: not much, it was the first computer what were you expecting
Honestly, I think something simple yet useful like a program that could tell us if another program will endlessly loop or will eventually halt. That sounds simple and nice right? We could test our code to see if it will run correctly. Should be trivial enough.
