Title: INVAC Photoelectric
Post by: Parak on Thu, 04 November 2010, 23:19:06

Yeah, this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170562128390) pretty much takes the cake for the most ancient "keyboard" I've seen so far. Look at the patent (http://www.freepatentsonline.com/3092310.pdf), it's virtually a typewriter! Some more info in plainspeak here (http://en.wikipedia.org/wiki/Keyboard_%28computing%29#Optical_keyboard_technology).

That looks suspiciously like an IBM 029 keypad, albeit with nixie tubes added.
