next SE/30 challenge: chime, screen, no pointer, death chime

[NE555]

in this next challenge for you, I have SE/30 logic board that has a good screen at first with a start up chime. You'll notice that there is no mouse pointer and after a second or two there is a short melody followed by a death chime.

It is running RAM test at the gray screen before the mouse pointer appears, so my first guess would be something RAM related.

That was a good guess. So yes, Faulty RAM
