The initial slide rule, the SR-10 is a four-function machine with additional function keys for reciprocals, squares, and square roots. Because both entry and display can accommodate a two-digit exponent, the new TI calculator can handle eight significant digits in scientific notation through nearly a two-decade range, positive and negative ...

Texas Instruments described the SR-10 as an “electronic slide rule calculator,” hence the “SR” in the name. The first version of the device, introduced in 1972, did not have the mark SR-10 on the keyboard.

Comparing the feature sets of the TMS0106 (TI-3500), TMS0120 (SR-10), and TMS0602 (SR-11) shows the limitations of the TMS0100 and explains the move from Texas Instruments towards architectures with scalable ROM configurations like the TMS0200 Building Blocks for Desktop Calculators introduced in 1973 but most important to the TMC0500 Building B...
