This is the Doughnet Adapter, a very special network adapter I assembled in 2000 or 2001 from a Dunkin’ Doughnuts doughnut hole and a Compaq loopback cable. It has occasionally been branded with an N, but this seems to fade a year or so after it’s written.
I’ve kept the Doughnet Adapter in one of the overhead cabinets in my cube since I made it, finally bringing it home tonight so that I could photograph it.
A few months back I broke off a small piece from the bottom and tasted it. It is rancid, but still quite sweet and smells faintly of vegetable oil.
