The calculator as a built-in battery pack which I have removed from
this one because it was leaking acid. They are two AA size
batteries and could probably be replaced by two modern NiMH
batteries. It still works using a power adapter,
At the back of the calculator the following text can be read: "New unique display — Larger, Clearer, Brighter, Easier on the eyes." I have no idea what the size of its predecessors’ displays might have been for this display is Very Small. It is a fluorescent display consisting of one display tube.
There are two LEDs above the display. The LED at the left indicates a non-zero value in memory. The LED on the right lets you know when to recharge the internal battery pack.

There is a newer version of this calculator, the commodore "Custom Green Line" GL-997R with an actual larger display.
