TI-57

The TI-57 was a programmable calculator made by Texas Instruments between 1977 and 1982. There were three machines by this name made by TI, the first was the TI-57 with LED display released in September 1977 along the more powerful TI-58 and TI-59. It had 50 program steps and 8 memory registers. Two later versions named TI-57 LCD and TI-57 LCD-II have a LCD display, but were less powerful (ran much slower) and had much less memory: 48 bytes to be allocated between program 'steps' and storage registers.
