My weapon of choice in the 1980s was the HP12C, and you can still buy them......

I have a PSION Organiser 2 model LZ64 with 64 k datapack full of survey computations, far better than a HP21

Used to have a couple of HP45A in the good old days with card readers

Still have an original Casio FX-570 Scientific (23 years old) which is in regular use - works fine but is banana-shaped after the b******d Statistical Analysis Professor (no idea what he was called but "Git" will suffice) knelt on it trying to open a window. Git.

...Casio FX-570 Scientific...

I just had a brain wave! Since i no longer use my old ipod mini as mp3, i could use it as a 4 gb backup disk, Cheers Gabe for reminding me to start using it again.

not only that, but how about this for useful?

I run that off a USB stick - fantastic to shift stuff around and surf in safety / privacy
