|Type:||Almost scientific calculator|
|Batteries:||AA x 2|
This is a calculator with some scientific functions, such as powers, roots, the constant π, reciprocals and percentages.
The calculator has memory, and the special "Σ"-slider, when set to Σ will automatically add a calculation's result to the calculator's memory when the "="-key is pressed.
Pressing the "Mout"-key twice will clear the memory.
I couldn't figure out what the "ALG - BUS"-slider does.
Just like the Triumph 81C, every key has its own spring.
