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..

Your usual thorough and amazing work Jake, thanks for these links, it makes it easy to see just about every HP machine through 2000 at a glance.

As a side effect, the images also confirm (as if this needed to be confirmed) that the orginal HP-10 is about the weirdest machine HP ever introduced. Look at that keyboard! But I still wish I could get my HP-10 printer working...
