Lifetime: Introduced: unknown

Notes: This 12 digit calculator has a screen that can be tilted. The purpose of this design decision escapes me, it manly makes the calculator fragile. In fact one of the segments on this specimen was already starting to misbehave. The LCD ribbon was already getting loose at both ends where it is glued to the PCB. This could be "fixed" by placing a cut part of a Post-it note to apply some pressure.

The "GT"-key is nice. It displays the Grand Total of all performed calculations that were done after the last time the "AC"-key was pressed.

Take care not to type too many numbers. When you accidentally enter 13 numbers on this 12 digit calculator it will error out.

It is unclear to me what the "MU"-key does. It doesn’t seem to do anything.

The battery is in the lower part of the calculator.
