- Description
- This handheld electronic calculator has a black plastic case and a metal keyboard. It has an array of twenty-four rectangular black plastic keys. The meaning of the keys is indicated on the keyboard. There are ten digit keys, a decimal point key, a total key, four arithmetic function keys, a clear key, a clear entry key, a change sign key, and a percentage key. Above these is a row of four memory keys. The on/off switch is on the left edge. A mark above keyboard on the left reads: TEXAS INSTRUMENTS. Behind the keyboard is an eight-digit blue-green vacuum fluorescent display. A mark below the keys reads: TI-1265.
- A jack for a power outlet is along the back edge. A sticker on the back reads: US PAT 3819921 AND OTHER PATS PENDING (/) TEXAS INSTRUMENTS (/) Serial No. A 2028431. The sticker indicates that the calculator should be recharged using an AC9180 adapter/charger. It also reads in part: ASSEMBLED IN USA. Below the sticker is a compartment for a nine-volt battery (the cover is missing on this example). A mark below it reads: 1077 LTA.
- Compare the TI-1200 (1986.0988.074). The TI-1200 lacks a change sign key.
- Also compare the TI-1250 (1986.0988.053). It has the same keys, but different coloring of the keyboard and a different display.
