I have a Quadra 605. Used to work perfectly. I tucked it away in the closet for a few months until I got my 5.25" floppy drive. Took it back out to use ADT with the IIe card and I got the chime of death.

I took the IIe card, RAM, and VRAM out, plus disconnected the floppy and HDD, and it still chimes.

Fortunately, no sad Mac, just the chimes.

Any thoughts? I can't zap PRAM, it chimes before I can do that.
