Most common calculators in the forum?

[Maximilian Hohmann]

More items for the statistics have arrived in the mail in the last two weeks:

An HP-37E, advertised as defective, in excellent condition but with some internal connector problems which only show once it has been running for a few minutes:


A Ti-31 solar, a variant of the trusted Ti-30. Indestructible, no battery - just a solar cell and a capacitor, these things will definitely survive mankind. Does everything one needs to do with a calculator apart from programming:


A Ti-83plus. I lost count on which ones and how many of each of those I already have. If they sell for less than 3 Euros I buy them. Somebody hand-painted the worn parentheses keys. Whoever used this calculator before me should have bought an RPN model if he needs so many parentheses!


And now some bells and whistles, or rather colour and sound:
A blue Ti-82 stats. 1 (one!) Euro. Perfectly working and much nicer blue than that Hp49:


Another Smarties calculator. They come in two sizes and many different colors. This is a large blue one:


A musical calculator from Casio, the ML-81. Including clock, alarm and stopwatch, unfortunately it can not work with time values like other Casios. The display has a little stain from some liquid but the calculator works (and plays music, albeit only one octave):


And this one here belongs in every collection: the Disco Calculator! Colored light and disco music from every key pressed. I got it from France, but of course it was made in China. Recently I drove my wife mad by doing some actual calculations with it. The little video below is unedited and not very good but I hope that watching it will boost the sales of the woderful Disco Calculator!
