The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. It enhanced their earlier and calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other features. The SR-50 was introduced in 1974 and sold for US$170. It competed with the Hewlett-Packard HP-35.

  • Der SR-50 von Texas Instruments (TI) ist ein technisch-wissenschaftlicher Taschenrechner. Er war das erste TI-Modell mit trigonometrischen und Logarithmus-Funktionen. Das Kürzel SR bedeutet slide rule, engl. für Rechenschieber. (de)
  • El SR-50 fue la primera calculadora científica de bolsillo de Texas Instruments con funciones trigonométricas y de logaritmos. Fue introducida en 1974, vendida por US$ 170, y tenía una pantalla de diez dígitos más un exponente de dos dígitos para números de punto flotante. Usaba notación de infijo ordinaria, en oposición a la notación polaca inversa empleada por su rival, el Hewlett Packard HP 35. El SR-50 medía 5-3/4 pulgadas de largo por 3-1/8 pulgadas de ancho por 1-3/16 pulgadas de alto (147 mm x 78 mm x 31 mm) y estaba algo mentada por un paquete de baterías recargable de NiCd. Tenía 40 teclas, un interruptor on/off y un interruptor de grados/radianes. Según se informa, el "SR" significaba "slide rule" (regla de cálculo). (es)

  • SR-50 foi a primeira calculadora científica de bolso da Texas Instruments com funções trigonométricas e logarítmicas. Aprimorou as calculadoras anteriores SR-10 e SR-11, introduzidas em 1973, que tinham notação científica, quadrado, raiz quadrada e recíprocos, mas não tinham funções trigonométricas ou logarítmicas. A SR-50 foi introduzida em 1974, com preço de venda de US$ 170. Ela competiu com a Hewlett-Packard HP-35. (pt)
