Very popular calculator of the mid 1970’s. This is also the very first
one-chip calculator. There is quite some information on this calculator
in the DATAMATH CALCULATOR MUSEUM, another calculator collector. See: Texas Instruments TI-1250 (Version 1) (link validated 2024-01-13).
It has basic functionality and memory. Operations are automatically repeated when pressing the = key. Errors are indicated by rapidly flashing the LED display. There is no indication of a non-zero value in memory. The memory is not cleared by pressing C or CE. Thanks for finding this one, Arnoud Helmantel. |
