Does anyone have a ready reference on two items I recall
seeing previously?
  1. An article (in an IEEE magazine, I believe) about IBM wireless
     terminals.  They used infra-red emitters and detectors along with
     an ALOHA scheme of networking several terminals in a room.
  2. Another (again IEEE, I think) article on IBMs chord keyboard.
Thanks.
