content: This handheld electronic calculator has a tan, black, and brown plastic case with an array of twenty-five sloping plastic keys. These include ten digit keys, a decimal point key, a pi key, four arithmetic function keys, a total key, an exchange key, and two parenthesis keys. The top row of keys includes a clear entry/ clear key, an EE (enter exponent) key, a change sign key, a function key, and an ARC key.
label: Description
content: Many of these keys have a different effect if the F or ARC key is pushed. Functions found in this way include inverses, exponents, powers, logarithms, square roots, trigonometric functions, inverse trigonometric functions, conversion from radians to degrees, conversion from degrees to radians, and factorials. The calculator also has memory keys. Behind the keys are a degree/radian switch and an on/off switch. Behind the switches is a twelve-character display that shows results in scientific notation, including eight digits of the result, two digits of the exponent in base ten, and the sign of both the number and the exponent.
label: Description
content: A mark along the front edge reads: SCIENTIFIC SLIDE RULE 63R. A mark behind the eight-digit fluorescent display reads: Rockwell. A jack for a power cord is on the back edge. A sticker on the back gives operating procedures and reads in part: Rockwell (/) International Microelectronics Product Division (/) Anaheim, CA 92803. Further text reads: Calculator Model 63R (/) Assembled in Mexico (/) U.S. and Foreign Parts. Further text reads: Ser [sic] (/) No. 174452.
