Commodore S61

The Commodore S61 is a bit of a hand full.

Commodore was a prolific manufacturer of calculators in the 1970s culminating in a range of scientific, financial, and statistical calculators with an impressive array of keys.  The large N60 (for navigation calculators) and the S61, here, were the ultimate models having 60 keys, most having more than one function.
