[Eddie W. Shore]

A nice, credit-card sized scientific calculator.

Unusual keyboard layout; Factorial and Pi are primary keys, yet Square Root is shifted; also using a^x for xth power (vs. expected y^x).

Nice find!

I can't resist to share here three of my small machines, two of then also from Canon, despite being older than your FS-5.

They are the Canon F-55S Scientific/Statistical and the Canon Card LC-61 and both have the same size, being a little bit bigger than a credit card despite its huge thickness when compared to a real card.

The 3rd one is the Casio SL-800 that was probably the first unique true card sized calculator, even on the thickness. Casio used innovative materials and technologies at the time to be able to design and making it.

I must agree as an owner of one FS-5.

The keyboard is suprisingly good for a such a small keys, much better than most modern TIs or Casios etc.
