Performa doesn't start up

My first Mac, Performa 5220, doesn't start up.
I bought this Mac in 1996.
It's been ten years since I started using it.

I used the emergency disk but the hard disk couldn't be found.

I heard a sad melody from Mac yesterday.
Does this mean Performa is no more alive?

I will read "The Macintosh Bible", which I have forgotten about for a long time, and find a solution.
