Hexadecimal numpad

Question

The project I am currently working on requires a lot of hexadecimal numbers to be entered into the code.

I once saw a pic of an old keyboard with a hexadecimal numpad (has A-F letters on it also) replacing the normal numpad. Anyone know where I can get one of these?

Answer 1

IPv6 Buddy -keypad should work well for hexadecimal input.

If you can get your hands on one of the retired space shuttles, they have one!
