Abstract
The TI-1250 was considered a "fully-loaded" four-function calculator in 1975 operating on 9V batteries. The calculator is accurate up to 8 digits and features a red LED display. Originally it was manufactured in the United States, but production was soon shifted to Hong Kong. New display designs in conjunction with additional memory of the later TI-1250 calculators increased sales. Prices for these similar TI calculators saw a drastic decrease in price with the TI-1250 being $24.99, compared to $119 for four function TI calculators like the SR-11 to the right, just 3 years prior.
