Description
This handheld electronic calculator has a light gray plastic case. It has ten digit keys, a decimal point key, four arithmetic function keys, and a total key. The keyboard has special blue squares surrounding the keys for pi, square root, reciprocal, percentage, and clear entry/clear. The four memory keys also have a blue background. The eight-digit green fluorescent display is behind the keyboard. A mark at the top left reads: BOHSEI. A mark immediately above the display reads: MODEL 1000. The on/off swith is on the right side.
The case has a compartment for AA two batteries at the back. A gold-colored paper tag reads: Serial No. (/) 932770 (/) MADE IN HONG KONG. The calculator has a socket for an adapter on the top, but no adapter in this example.
Newspaper advertisements indicate that a printing desktop electronic calculator was sold under the Bohsei name in 1977. A February 1978 advertisement in the Chicago Tribune indicates that the Bohsei Model 1000 was then on sale at a special price of $8.88.
