Hi all,
     Today I was playing with a rev E and a rev. J (at the same time),
and I found something very weird:  I was in the equation editor, and
knowing that the J is faster at deleting chars, I put in a BIG sumnation
expression and fine, the J was faster at deleting, but then I evalutated
the two, identical expressions; I got two VERY different answeres.
(it was the sume of (5*x^2*ln(x)/sin(x)) as x goes from 1 to 100, don't
ask why.  The answeres were like this: -1700 or so for J and 19000 or so
for the E). So there you go.

     Other differencers that I noticed is that 1) the J screen is more
wavy, i.e. it flicks more, 2) when the J is turned on, some garbage
comes on the screen momentarily everynow and then, that never happend to
me on an E.

     Any one else see some other stuff?
