Description
This handheld electronic calculator has a tan plastic case and seventeen rectangular plastic keys. In addition to ten digit keys and a decimal point key, it has a clear entry/clear key, four arithmetic function keys, and a total key. On the left on the brown and off-white keyboard is an on/off switch. Text above it reads: 850 NOVUS. Behind the keyboard is an eight-digit LED display. A compartment for a battery opens on the top of the back.
A jack for a power adapter is on the left side.
Advertisements indicate that the Novus 850 was introduced by the fall of 1974 for a price of $25.88 and sold at least through April 1977, when it sold for $4.99. The two-tone keyboard appears only from 1976 onward, hence the dates assigned.
Compare 1986.0988.306 (a Novus 850) with 1986.0988.305 (a National Semiconductor 850A).
