RPN handhelds with VFD
Are there calculators with vacuum fluorescent display other than the Various Elektronika models and the Omron 12SR?

Cheers,
Harald

Lots of early Casio calculators - e.g., Casio fx-10, Casio fx-201, Casio AL8, Casio CQ-1 ..... at least, all these calculators have green glowing displays with the display elements inside a glass tube. I think they are vacuum fluorescents.

Not RPN, though.

I can't think of any RPN ones, apart from the Электроника models. I don't know much about the rarer RPN calculators so there might be one.

That was my bad, I ment to write "RPN calculators" in the text as well as the topic.

Yes. The Sinclair Programmable -- which looks like a Sinclair Oxford, but has a very limited program memory (24 steps) that is not preserved on power off. Despite this, the calculator came with a large program library. I have one of these in my drawer, it works, but due to inaccuracies, or rather, imprecision, it is little more than a collector's item.

Thanks for the hint! I just secured one off ebay UK Smile
Would you happen to have the documentation for it? My example will come as the bare calculator.

I saw at least two Czerweny (or some similar spelling) RPN machines in the early 90s, I think they where LED based at least one of them, the one that wasn't programmable. They were supposedly produced in Argentina, too.
