The TI-1070 was introduced in parallel with the TI-1030, the first US-built slimline calculator from Texas Instruments. It used a low-power CMOS integrated circuit manufactured by TI instead the Toshiba circuit in the previous TI-1750.
The keyboard is similar to the TI-1200 designs and they suffer all from the same problem of bouncing.
Simply by comparing the designation of the integrated circuits of some calculators you'll get the other members of the slimline LCD calculators and the relation ship between the Basic and Scientific models.
• TP0314 TI-1070
• TP0321 TI-50
Please notice the rounded design of the display frame found only with the TI-1010, TI-1030 and TI-1040.
In Spain a similar calculator was sold under the TI-1071 designation.
