I don't have one to measure, but the 1991 Psion series 3 has 13.5 keys per row on a 165mm-wide keyboard.
http://en.wikipedia.org/wiki/Psion_3 Maltron's designs are a long way from simply being scaled Qwerty keyboards, but they've been around since the late 1970s. They might be helpful as an example of what had already been considered by 1993. http://www.maltron.com/ http://en.wikipedia.org/wiki/Maltron_keyboard Steve _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
