The Panasonic 2602 is nice elegantly design electronic calculator. Uses 2 D size battery. Suitable for desktop or handheld. More suited for handheld. The heavy battery made it stable on the desktop. Design for repairs if needed, the calculator is easily open by removing two screws inside the battery compartment. Useful key to have is the double zero entry key, save keystrokes if entering large numbers.

Simple 2 PCB design. Keyboard has goldplated contacts on the
keypad side.The keyboard circuit is very well though out, unlike
some clumsy design seen in Casio calculators. |

Well lit 12 digit VFD green flourescent display.

| The rubber pads are replacements. |

The circular felt pad is a replacement. It helps to keep the battery firmly in place.
The original is a soft foam pad that is worn with age.

Nice clean negative battery contact.
