Bridgeport for CNC, what to look for?

Hello group!

I've been looking for a CNC victim mill for a few years and came
across a Bridgeport on Craigslist for 650 near Seattle. I'm going to
go look at it tomorrow. What should I be looking for?
I've only worked on lathes, mills are a new to me. It seems like they
might have different kinds of problems.

It has hydraulic cylinders in place of screws and handwheels for the X
and Y travel.

Also wondering about moving the thing.

Thanks in advance for any tips/advice.
