- Description
- This compact, light desktop printing electronic calculator has an array of nine light gray digit keys at the center, with a zero bar and decimal point key below this. On the left are clear, percentage, division, multiplication, and equals keys. On the right are total, #/S, subtraction, and addition keys. Above the digit keys are memory, F/A, and arrow keys. Behind the keys is a paper tape to print entries and results on special thermosensitive paper. This is the only display of entries and results.
- A mark behind the printer reads: TI-5050M. A mark at the front reads: TEXAS INSTRUMENTS. A mark on the bottom reads: TEXAS INSTRUMENTS (/) electronic calculator (/) MODEL TI-5050M (/) SERIAL NO.
