Got a (in my sig) Q605 - 33Mhz hack, full RC040, 64MB SIMM, 250MB hard disk, PDS etherent, I think MacOS 8.1

It was put away working about 2-3 years go.

Pull it out, nothing.

Dug out a good battery from my inventory (read: garage) and popped it in.

I can hear the startup chime, and then I hear this 8-10 note song, but no video, nothing.

Removed 64MB SIMM, same deal. Removed Ethernet card, same.

Any ideas? Never heard a Mac sing like that...of course, hopefully it's not a death chant...
