The TI-5135 was introduced as an economical printing calculator for office and home. It features a 10-digit display and a thermal printer quiet enough to be uses at home. Beside the usual 4-function memory an independent add register is available.
this TI-5135 manufactured in 1980 reveals an internal construction very similiar
to the TI-5040 known since 1976 and the PC-100
printing cradle introduced already in 1975.
The electronics of the TI-5135 is centered around the TMC0263 calculator chip, obviously the third member in a line of customized solutions for printing calculators. We identified so far:
The TI-5135 was the last Texas Instruments printing calculator based on their own technolgy, the successor TI-5130 - followed within one year - was designed around an impact printer for plain paper and manufactured by Toshiba TEC Corp. in Japan. The TI-5040 II introduced in 1982 used once again thermal printing technology.
The TI-5135B introduced in 1988 was manufactured in Taiwan, PRC.
