Black Piano
All the usual features you expect in a calculator, but with the keys laid out in the form of a 20 key piano keyboard.
The switch to the right of the MC (memory clear) key has 3 positions. In one position the unit operates just like
a calculator, in another, just like a keyboard and in the third postion it does both together.
Play yourself a tune while doing your calculations!
In addition there is a small LCD display and two recessed red buttons. The keyboard calculator came without any
instructions. I think the small display is a clock and the red buttons are for setting it.
