Mark 50

Not a bad little package! The Mark 50 has the typical power of a scientific calculator, but only has 8 digits in the display. Thus it loses a bit of precision when numbers are shown in scientific mantissa-exponent form.

The styling screams "electronics" to me - as if it were some sort of meter and not a calculator.

Mark 85

Nothing fancy here, but crisp, clean styling nonetheless.
