Hi people.
Well Arno, sorry u right, i did a little mistake with the formula. Well :
100000 / 63.5 * 260 =~ 409449
Them Arno, what is the meaning of this value? or does this value
have some relation with HP values?
Thanks, for your info, i still have some doubts about went to
change my tapes.
See u!!!
