The auction should be over in less than 24 hours and it's still down to less than 50$, so guess you'd better check it out @ ebay as soon as possible. You don't get many chances to get your greedy (and... ugh... slightly decomposed) hands on a proper N64 Dev kit you know. To use the words of the seller:
This isn't just any Nintendo 64. This is one of the development game consoles Silicon Graphics used to work on the N64. The unit is an original N64 motherboard mounted in a custom Plexiglas case. The case has been cut to allow to controllers to be plugged in, a cartridge to fit and cables to exit the back. The Plexiglas case is hinged and the top opens to allow easy access to the insides.
