Calculators (7) : Texet 880A Executive

Texet made this calculator in 1978 in HK, powered by a Texas Instruments TMS0972NL or a MOS MPS-7560 chip. The calculator has the basic arithmetic functions, it can handle negative numbers with the CS key and percentages. 

The calculator has memory store though the eight digit red LED display has no indicator to show the memory is being used. Helpfully there are three separate keys that can clear the memory!
