Ten classic electronic calculators from the 1970s and 1980s

I am so sad that...

I was actually a professional programmer of the HP41C for a while in 1981/2 (they were used extensively by petroleum engineers in the oil companies). I wrote several complex analytical tools for reservoir engineers and geologists using that little puppie!

I had a number of 12C's, which are truly fabulous financial calculators. I also had the other 2 HPs in the list but my favourite was the HP67, because of the sheer number of buttons and the integrated magnetic strip reader.
