YESSSS, i am a true nerd. i finally modded my calculator. (man that sounds pathetic) but hey, i'm proud of it, and i figured i'd post it here where it might be appreciated. anyway, just to point out what i did, i got fed up w/ the amount of batteries this beast went through (i use it at work so its on a LOT), & since i'm inherently cheap & lazy i decided to remedy the situation. I went to jameco, my favorite online electronics place & found a 6volt wall wart & a power jack to plug it into. i then removed the back of the unsuspecting TI & cut *gasp*
an opening for the jack to fit in the side of it & used epoxy to hold it in place & act as filler for the seam. i then soldered wires from the jack around to the battery posts & reasembled it. works great & transitions from battery to wall power quite easily.
lemme know what you'all think.
