There is a sort of a programmer's calculator hidden in as one of the
modes of the calculator built into my PalmOS-based Handspring Visor.
It has the Hex/Binary/Octal/Dec modes and the logic and arithmetic
functions of the classic Programmer's calculators. It's probably the
'default' calculator for all of the PalmOS (~3.0) devices from various
vendors (including Palm, if you must)

It is not anywhere as 'nice' an option as a classic 'real button'
calculator, lacking real buttons (touchscreen mapped keyboard) but
something that will do from time to time. And Visors and Palm PDAs of
that vintage go fairly cheap on eBay these days, particular old and
less 'glamorous' models with limited memory and greyscale/Black&White
screens.
