The Unisonic 1499 - rare as can be and has hyperbolics - Gene - 12-29-2016 04:21 AM
The inverse key works with the LN, LOG, and trig and hyperbolic trig functions. Note the usual Unisonic key colors: white, blue and orange. Note the brushed aluminum / stainless steel coloring.
But this has a red led not a green display. It also has a brown body. The D R G switch is humorous.
This is the ONLY model 1499 I have ever seen and I've been looking for 20+ years. If you find one, grab it. No other unisonic model has hyperbolics. The 1299 model has other functions this 1499 does not have, but this is the rare one here.

How does it do on the Calculator Forensics, i.e. how accurate are the transcendental functions?

The result is 8.999670079, the same per the table on rskey.org as the Rockwell Anita 1041.

Hi Gene,
Nice calc, is the display red led, or is it a fluorescent display with a red cover or filter.
I have only seen a handful with the red flouro cover combo.
Happy new year to all
Ray

It is an LED.
