>Note about CMOS chip failure:

CMOS memory chips are more delicate than NMOS because the NMOS chips usually
have some sort of discharge path.  However the subject wavering on the screen
I am sure is the same as on my machine which just makes the screen appear to
be moving slightly.  This coupled with the whiter color of the screen over
my Plus screen, made the SE a little bothersome.  I didn't mind but I am 
someone that concentrates more heavily on the screen could find it objection-
able.

To reiterate what another posting said, it does appear to be caused by the
stock squirrel cage fan.  I just returned from MacWorld Fair where I bought
the SE silencer fan and both fan noise and screen jitter have gone away.
