This calculator is the second one I ever bought. I don’t remember what the first one was, but when I got home my father said I had made a stupid buy (I bought a plain calculator for about $25, I was young at the time, about 12 years old, and $25 was A Lot Of Money). I then exchanged that calculator for this one in the shop where I bought it (with the complaint that it had a Terrible Bug, the calculator I bought would shamelessly take the square root of -9 and claim it was -3. This was a good enough reason to change it and buy the TI-30). This calculator was just a little bit more expensive but could do quite a bit more.
When I bought this one however I didn’t have the faintest idea what a sine or a logarithm was but it was fun to play with. Especially the power save mode.
To save power, the LED display would show a running "period" after a period of idle time, which was quite funny because it was so "Disco Like", which was quite the thing at the time...
According to other sources on the net, this calculator sold particularly well.
The TI-30 is identical to the TI SR-40, but was cheaper because it uses a 9V battery instead of a rechargeable battery pack.
