Omron 12SR - Harald - 08-21-2017 05:34 PM

Does anyone know anything about the Omron 12SR?
I have just bought one and can't wait for it to arrive.
It usese a 14 digit VFD (which is how it caught my attention) and seems to be functionally quite close to the HP45.
But I don't know when it was built, what technologie it uses and how rare it is (not even by how much it was overpriced Smile)

Any info would be appreciated.

Cheers,
Harald

Is the manual enough? Wink
No?

Same site: inside and outside.

Thanks, I hadn't found that yet!

FWIW, this calculator was the first to include hyperbolic functions, beating
the HP-32E by at least a year. The MOSTEK chipset was also the basis for the Sanyo CZ-2901, APF Mark 55, Privileg SR 54 NC and Corvus 500. Only the Sanyo has a green VFD like the Omron, the rest are red LED.

The first "RPN" with hyperbolics ?

the SR-50 in January 1974 had hyperbolics.

? :-)

Yes, I didn't think I had to add the RPN qualifier when posting in this subforum. Wink

Hi there. There were at least four calculators based on the Mostek processor with an identical function set--Omron 12SR, Corvus 500, APF Mark 55, and Privleg SR54-NC.

TK Enterprises published an extended manual for these, Everything You've Always Wanted to Know About RPN (But Were Afraid to Ask). Katie Wassernan's site wass.net has a PDF of this book. Here is the URL of the PDF for the book.

That would be the HP-32E from the 1978 Spike/Spice series. It also brought back the Woodstock HP-27 Normal Distribution function. And the 32E could calculate the inverse normal distribution.

In addition to Michael's good list; there are three others, sort of.
- The Omron SR 12 was also sold labeled as the General Electric CE-93
- The Corvus 500 was also re-badged as the Dumont Corvus and the Emerson E12

Then there's this one.

Thanks for the history lesson correction. Much appreciated.
