Omron 12SR

[Harald]

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 )

Any info would be appreciated.

Cheers,
Harald

Is the manual enough?
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.

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.
