RE: Keyboard Layout HP-41C and early models
Hi,
For what it is worth, a presentation was made at the 2000 HP conference in Los Angeles, surveying calculator keyboard keypad layouts from the HP35 up to the (ill-fated) Xpander. The presentation paper is located here and a copy of the presentation slides, comparing images of all the keypads is here.. Jake |
