- Description
- This handheld electronic calculator has a dark brown plastic case and twenty-three rectangular plastic keys. These include ten digit keys, a clear entry key, a clear key, a decimal point key, four arithmetic function keys, a total key, four memory keys, and a percentage key. Left of the top row of keys is an on/off switch. A mark above it reads: 835. A mark to the right of this mark reads: National (/) Semiconductor.
- Behind the keyboard is an eight-digit LED display. A jack for an adapter is on the left side. The back of the calculator has a compartment for a battery. Text at the bottom of the back reads: MADE IN HONG KONG.
- Compare to Novus 835 (1986.0988.276), which was also made by National Semiconductor. Also see the National Semiconductor 835 (1986.0988.229). These two calculators have a % key, which this one does not. Also, on the 835A the clear and the clear entry keys are distinct.
- Reference:
