It has a footprint fractionally bigger than a credit card.

Technical details:
Display is 8 digits, LCD.

4-function, %, memory, square root.

Size: (slightly bigger than a credit card).

Made in Japan.

Introduced: 1980[1].

Sanyo, on its website[2], says about the "Amorton" amorphous silicon solar cell: "Unlike crystal silicon, in which atomic arrangements are regular,  amorphous silicon features irregular atomic arrangements ... . As a result, the reciprocal action between photons and  silicon atoms occurs more frequently in amorphous silicon than in  crystal silicon, allowing much more light to be absorbed."
