Bowmar Math Mate II Handheld Electronic Calculator

Description
This handheld electronic calculator has a cream-colored plastic case with a dark brown plastic keyboard and tan plastic keys. In addition to ten digit keys, it has a decimal point key, a total key, keys for the four arithmetic functions, a percent key, and a clear/clear entry key. The on/off switch is right of the clear key. All of these keys were on the Math Mate. In addition, the Math Mate II has a key to turn the memory on and five keys that can do double duty as memory keys.
Behind these is an eight-digit LED display. A mark on the display reads: math mate. Another mark there reads: by Bowmar.
The socket for the AC adapter is on the right side. The back of the calculator has a compartment for a battery as well as two rubber feet. The calculator has no serial number.
The object and a sheet of instructions fit in a cardboard box. A mark on the back of the box reads: math mate by Bowmar (/) The first inexpesive calculator (/) good enough to be called Bowmar. (/) Fully featured (/) Quick and easy to operate (/) Full one year guarantee. Further text reads: Printed in USA. Another mark reads: Assembled in Mexico. A sticker attached to the back of the box reads: CONTINENTAL MICROSYSTEMS (/) P. O. Box 1964 (/) NOGALES, AZ. 85621. A sticker on the other side of the box reads: math mateII (/) with (/) memory.
Bowmar introduced a calculator in 1971, and had successful sales in 1972 and 1973. Assembly began in Mexico in mid-1974. The company went bankrupt in February 1975 and stopped building calculators in the middle of that year. By 1976 distribution of Bowmar calculators had been taken over by Continental Microsystems.
A May 8, 1975, advertisement indicates that the Math Mate II regularly sold for $34.95 and was then on sale for $29.88.
