ti45.jpg (23667 bytes)So you thought you knew everything about Texas Instruments scientific calculators. You knew that the TI-45 was none other, but one of the many European variants of the incredibly successful TI-30 line, this time a TI-30 (or SR-40 if you prefer), but with a green vacuum fluorescent display.

Guess again. This TI-45 is a completely different type of animal: it is an LCD scientific calculator with a built-in thermal printer. I came across this machine by accident; although non-programmable machines aren't what I am usually after (I have, in fact, since traded this machine), when I heard that this is supposed to be an LCD printing calculator, curiosity overtook me and I made the purchase.
