I too am interested in all of the above -- I have deleted over 50% in the
interests of brevity.  I am interested in converting a 1200XL, 800XL and a
130XE all to 256K.  That's correct, since it only has a 90 day warrenty 
which is almost up, why not upgrade the 130XE to 256K also!!!

Please add me to any mailing list.
