And you can run them on a PC104 system with a serial LCD and a
custom keyboard that is designed for your application, and it
will be about the size of a top-end calculator.

We're thinking about doing a benchtop instrument with a PC104 CPU
(geode or something) inside and a small color VGA on the front panel.
We'd program it in PowerBasic, booting off flash. Should be fun.

One of my retirement-list projects is to manufacture a clone of the
HP-35 calculator, with some little cmos uP inside. The hard part would
be getting the keys to feel right.

A PalmOS device would be a *far* better choice for your application.

"EasyCalc" is a good free programmable calculator available for PalmOS
devices. There are a few languages for the Palm, notably python, if you
need more than simple programmability.

If you want to _connect_ it to your ultralight, you could get an older
RS-232 based device (Ebay?) -- might be easier than USB.

But it won't run off of a pair or CR2032 batteries through a couple years
normal usage now, will it? :)

Not unless you can use the CR2032s as fuel for a fusion reactor.

This is John Larkin for forever:
I wouldn't. Calculators are for arithmetic, computers are for
programs.

Sometimes I find myself using the HP48 emulator (Emu48) in my computer
to write a program to do calculations.

Takes less time than loading Excel and using VBA, or write a "quick
hack" in VB.
