Currently at Reed Space there is an exhibit of very cool tech objects, courtesy of Gizmodo. Well worth a look if you are in NYC, even though it is a bit out of the way when it comes to the subway.
(Gizmodo event wrap-up.)
Oldest first. Portable typewriter, although based on its looks it could be a modern steampunk interpretation.
A very cool old AT&T protoype videophone. I have a copy of an advertisement with this in it, a man is using it to sell hats, and he's wearing a Mickey Mouse hat, so it looks like he is adjusting antennae on his head.
Apple prototypes -- similar style to the Apple IIc.
Homebrew portable Atari 2600!
TAM! I had never actually seen one before (just pictures), they are fairly rare.
Chumby! My iPhone does most of the same things, though, but I like the idea.
Laser etching! That little light in the photo? Laser! Awesome.
