Really old digital camera

Years ago when the digital camera first came out my school bought one. It's now really obselete and they were thinking about getting rid of it so I said I would take it. Unfortunately I can't get it to work. I put in 4 new AA batteries but it won't turn on. Unlike some cameras this one had a 4mb memory card. That's the lowest amount I've ever seen on a memory card for a camera. Luckily my computer does have a slot for that kind of memory card but all that was on it was a very dark picture that was taken inside somebody's house. I might be using this camera in a future video as one of my puppet's cameras. I don't know which puppet it'll belong to yet.
