The BA II Plus Professional financial calculator in its package.
The display of the BA II Plus Professional gives a perfect contrast and high readability.
The upper shell of the housing is covered with a wonderful keyplate made of brushed aluminum. Parts of the plate are polished and give a silver design.	The keyboard uses injection molded caps instead the usual rubber parts. Unfortunately they are only printed - the SR-50 made use of double-shot injection molding.
The backside the calculator sports a sliding battery cover and hides the 4 screws under rubber pads.	Inside the BA II Plus Professional we noticed two metal plates, they give the calculator a strong weight.
This keyboard of the calculator is composed once again with small snap-action discs similar to the Klixon style construction of the SR-50.	This printed circuit board (PCB) of the BA II PLUS Professional with just a single-chip calculator circuit.
