Does anyone have access to a copy of the electrical schematics to the
800XL and who can tell me the function of resistor R32?  There is a 
conflict between several of the various 256K upgrades as to whether
you add a wire to this resistor or you add a wire after removing the
resistor.  I have now installed the Newell 256K upgrade in my 800XLE
(my nomenclature) and in doing so, I removed the resistor per Newell.
However, the instructions for the similar RAMBO XL kit showed leaving
this resistor and merely adding a wire to it.  Does anyone know why?
I have noticed that on some menus that I have the solid background has
verical strips of different shades showing, but this may be due to some-
thing else entirely.  If this resisitor has nothing to do with picture
quality, then I will leave it off as I don't see any evidence that it
does anything else.

Surely there are a group of persons out there who have converted 800XL's
to 800XLE's?  Can we get a discussion going on how you did the conversion
and how well it went?  My total time was about 1 1/2 hours, the most time
spent was modifying the plastic housing to allow the wires to go thru the
mounting hole and down underneath the board.  Of course, I cheated and
used color coded wires so I did not have to keep tracing down wires with
an ohmmeter when wiring the leads to the PIA chip socket.  I also had
some good suggestions ahead of time from David Young.
