Do you mean besides the unmarked grounded conductors used at breakers and the lack of grounding conductors?
They all look like Cutler Hammer breakers. And, they are all on.
Did it have 2 AC units?
Were the circuits run in conduit?
Can you post a picture of the entire cabinet, with the dead front off?
[Looking at my buddies house What is wrong here?

Hope that helps.
Take a another picture of the top half of the panel. Main breaker and neutral and ground bar are important features.
