Soundesign 8300 Desktop Electronic Calculator

<< >>
Description
This compact desktop electronic calculator has a metal and plastic case with seventeen indented keys, most of them square. The 0, addition/total, and subtraction/difference keys are twice the size of the other keys. In addition to the rectangular keys, there are nine other digit keys, a decimal point key, a multiplication key, a division key, a clear entry key, and a clear key. Above the keys is a constant switch, a switch to set the location of the decimal point, an on button, and an off button. Behind the keyboard is an eight-digit blue vacuum fluorescent display with another place for setting the sign. Text behind the display reads: SOUNDESIGN 8300.
The back of the calculator has a compartment at the top for four C (1.5 V) batteries. A sticker inside it reads: 19053-K0202. The “3” is largely effaced and the K is in red.
Below the compartment is a sticker with instructions. It reads at the top: SOUNDESIGN 8300 MACH II. It reads at the bottom: Made in Japan.
A jack for a power adapter is along the back edge, but this example has no adapter.
The calculator has a zippered plastic carrying case with a handle. A mark on the front reads: SOUNDESIGN.
