The TI "Programmer" (NOT to be confused with "programmable") was one of
the first basic calculators to offer hexadecimal arithmetic and
hex/decimal conversion. The LED display really ate batteries, and it
could go through a battery discharge in less time than it takes Windoze to
boot. But if you kept it plugged into the wall, it worked great.

Then they came out with a new model of it with LCD display. The batteries
got great life, but the keyboard tended to go before the batteries.

If you like having a calculator that includes hex, one of the really neat
ones is the Casio CFX-40 and CFX-400. It requires good eyes and good
dexterity, since it is a "scientific" calculator in a watch. It's biggest
weakness was a tendency to crack between the display and the keyboard.
I've replaced the case on several.
