I have a Sharp EL-506TS scientific calculator. I have other calculators.

My specific model is an EL-506TSBWH which is the model they sell in Australia. It's white on top. The EL-506TSBBW model sold in North America is black with white accents.

I got this Sharp EL-506TS model out of nostalgia for my Sharp EL-546L which is the scientific calculator I grew up with. The EL-506TS is the latest in the EL-5xx line.

I purchased mine from here: Sharp Scientific Calculator 470 Functions 2-Line Display EL506TSBWH

The specifications are here: Sharp EL-506TS specifications

The manual is here: Sharp EL-506TS Operation Guide

There's extra information from their Australian website over here: https://sharp.net.au/products/el506tsbwh-advanced-scientific-calculator-white
