	Almost a year ago I had my Mac+'s motherboard replaced --
the y told me the CPU, RAM, and everything else was just fine.  But
my Mac has never been the same.  Yesterday and today, I got the sad
Mac error code 0300FF (a RAM test failure) which was no surprise,
because the usual pattern of diagonal stripes that follows a cold
start was glitched.  Badly.  Columns of extra pixels in the middle
of the screen and columns of missing pixels on the right side.

	I waited for the Mac power supply warm up.  No effect.
Thumping the sides of the Mac didn't change things -- same ugly
patterns followed by the sad Mac.

	Then I put the Mac on its side and spanked its bottom.  And
voila!  Up and running without a single misplaced pixel.  First
there was the cold start and the warm start, and now the Han Solo
start.  Does anybody know what's really wrong with my Mac?
