The
TI-1750-III carries a famous name, it seems to be the successor of the first TI
LCD calculator, the TI-1750.
Well, to be honest
with you,
under the hood of this TI-1750 III is nothing else than another design of the original TI-1030
calculator centered around a TP0311 single-chip calculator circuit. Not as exciting as the TI-1760 DataCard.
The same housing was used for the Time
Manager sporting an integrated clock with two 24-hour alarms and a stopwatch.
If you compare the suggested retail price (SRP) of three (technically identical) calculators you'll notice:
• $10
TI-1001
• $12 TI-1031
• $15 TI-1750 III
That's the power of marketing!
