Lifetime:	Introduced: 2000 Terminated: unknown
Notes:	The CASIO fx-82 series started with the CASIO fx-82, an ordinary scientific calculator. But But CASIO kept extending this line, turning it not into just a model number but a whole calculator series. Trying to make it the non-programmable scientific calculator for school use. So far I’ve found mention of the following types: CASIO fx-82 CASIO fx-82A CASIO fx-82B CASIO fx-82C CASIO fx-82D FRACTION CASIO fx-82L FRACTION CASIO fx-82LB FRACTION CASIO fx-82LP CASIO fx-82SX FRACTION CASIO fx-82 NASER CASIO fx-82SUPER FRACTION CASIO fx-82SOLAR FRACTION CASIO fx-82TL (this one) CASIO fx-82MS CASIO fx-82MS-2 CASIO fx-82W CASIO fx-82ES PLUS CASIO fx-82EX CASIO fx-82NL CASIO fx-82ES PLUS CASIO fx-82CE X CASIO fx-82CW CASIO fx-82MS 2 CASIO fx-82 SOLAR II This one is one of the most practical and functionally complete non-programmable scientific calculators I know. It has hardly anything to do with the CASIO fx-82 itself. Expressions can be entered as a formula. But the calculator automatically switches to the old fashioned method as well. It’s all quite intuitive. To calculate "9^3+15" just type "9", "x^2" "3" "+" "15" "=". However, to square the answer again, just type "x^2" "=". The display then automatically shows "Ans ^2". It’s a little hard to explain but quite easy to work with. Expressions can be re-performed and edited using the "replay" and " INS "/"DEL" keys. The calculator has a two-line display (hence the TL type designation). The top line is alphanumerical and contains the typed expression. The bottom line is numerical and contains the last calculated result. The calculator has 9 memories, named A, B, C, D, E, F, X, Y and M. They act as registers, but the M register is automatically added to when the "M+"-key is pressed. Also, the E and F registers are used as well for answers to two-parameter conversion operations such as "Pol(" and "Rec(". A very nice feature is one I always used to program myself on programmable calculators. When the display shows a result like, say, "0.33333333333", press the "Ab/c"-key to reveal the fraction "1/3". The algorithm to perform this calculation is really simple, I don’t know why it took so long to add this feature... The statistical and regression functions of this calculator are extremely elaborate. The calculator is fast, and also important runs on one AA battery. A screw driver however is needed to replace the battery. Just the one thing, why put "S-V.P.A.M." on the front? It is of course quite obvious what this stands for isn’t it? And why I’d want a calculator with "S-V.P.A.M.". Isn’t it? Anyway, according to CASIO it stands for "(Super Visually Perfect Algebraic Method)". All in all, I think this is one of the better non-programmable Scientific Calculators. Thanks for this one, Jan Hurstjes!
