This small desktop electronic calculator has an array of nine digit keys with a zero bar and a decimal point key below. A total key is on the left, and keys for the arithmetic functions and for cancellation are on the right. Behind the keyboard is a 10-digit vacuum fluorescent display.
The bottom has a cavity that holds five batteries and a red ribbon (the calculator presently has no batteries). A jack for a cord is at the back, but the cord is lacking.
A mark on the front of the machine reads: SPERRY REMINGTON 1005B. A mark on the bottom reads: SPERRY REMINGTON (/) TM (/) BATTERY SUPPLY 1.5Vx5 (/) or use AC ADAPTOR AD-4160 (/) 1W (/) MODEL 1005-B Made in Japan. A tag inside the lid for the battery case reads: 2101730.
