Someone at work found an old Audrey internet appliance and gave it to me. It was missing the stylus & keyboard, and was somewhat dirty. I combined that with a tar & nicotine soaked stylus & keyboard I bought on ebay, and after taking every component apart and cleaning it she came alive. I even wetn so far as to add an ethernet adapter with wireless bridge, all powered internally.
Of course, I loaded her up with the best OS image I could find and customized it quite a bit (including re-adding her signature "giggle" back to the startup sequence).
She isn't really much of a "mod", but with such a unique shape I just couldn't cut into her.
