telegraph & zeug
"An extensive set of pages mostly devoted to photographs of the author's collection of over 1000 telegraph keys and related bits of history. Tom Perera, who runs the site, appears to be just a bit obsessive; at least, it's hard to come to any other conclusion about someone who makes a solo dive to recover a piece of unused transatlantic cable. Lots of great old technology here to peer at, and links to many other telegraph sites around the Web." [via weblog v2]
