It's been a while since i worked on one but may have a couple in the back of the closet to look at.
I don't remember if it has a port for an external monitor. do you have any of the adapters or additional peripherals? Any system disks, a floppy drive?
Next I'd replace the PRAM battery. Also leave it plugged in overnight to see if the standard battery will take a charge. Let me know your finding and we'll see if we can get this gem up and running again.
First please tell us the exact model, see if it is this one:
