Phil Davis (author of "Beyond the Zone System" and many magazine
articles in Photo Techniques USA and its predecessors) has written a
program called ExpoDev for the Palm devices (no longer Palm Pilot
after the pen company sued them).  This is a replacement for the
handheld BASIC computer that he had previously written software for.
It does most (if not all) of the non-stereoscopic things Bob wants.
You can buy it at The View Camera Store (formerly Darkroom
Innovations). <URL:http://www.darkroom-innovations.com/> There is a
cardbard sliderule version (sort of like a pilot's E6B) that handles
many of the things the program does.

Bob Wheeler has written a Palm program called VadeMecum that does many
of the things ExpoDev does, but does not keep a database of exposures.
VadeMecum is available for a number of different handheld devices.
You can see it, and his papers on various photographic topics, at:

I've had a Palm IIIx for a while.  I have the Quartus FORTH
development environment for it (develop stand alone FORTH programs
directly on the Palm), but I haven't figured out floating point yet.
FORTH traditionally uses fixed point math.  My wife has the Metroworks
Code Warrior for the PC and Palm environments and has been busily
working away on her sock calculator
