It has a metal frame painted gray and ten columns of color-coded gray and blue-green plastic number keys, with a blank green key at the bottom of each column.

On the left is a register that indicates numbers entered for multiplication. Below it is a block of 9 white digit keys, with a 0 bar below. These are surrounded by further levers and function keys.
