Description
This handheld electronic calculator has a black plastic case and eighteen square sloping plastic keys (two of which are rectangular). These include nine digit keys, a zero and decimal point bar, four arithmetic function keys, a total key, a % key and a clear/clear entry key. To the right of the three uppermost keys is an on/off switch. A mark above the eight-digit LED display reads: Sears. A jack for a power cord is on the right side.
At the top of the back of the case is a compartment for three AA batteries. A sticker at the bottom of the case reads: SEARS (/) MODEL (/) NO. 728.5822 SERIAL (/) NO. 308598. It also reads: ASSEMBLED (/) IN MEXICO.
This calculator has a slot for a “wood-grained roll top” such as was used on some other Sears calculators of the era. It has no top.
