Last night, I watched a dvd on my mac... it worked. Also playing RealAudio. This is good.

Today I unplugged the mac in my bedroom and went out to the living room. I ejected the dvd and then... the screen went black. I hit the spacebar, nothing. I moved the display for no particular reason, and I heard the beginnings of the happy-mac chime... but it was cut off. Then it restarts again -- or did I hit the button? No, I don't think I hit the restart button... and it boots okay, except that the date has been reset to 1969.

This is a mac with hardware trouble.
