HP Calculators with native C-F temperature conversion

[calc-calcs]

It seems that the HP32E would be another alternative to get instead of the HP55 with that temperature conversion and LED display. For now I downloaded the Panamatik HP32 simulation and it works just fine, although the blue lettering on the keys is not very clearly visible due to the angle of visualization being a bit too steep. But it works until I can find the real deal.

Too bad the HP34C does not have that temperature function, as I could have converted one of my surplus HP21s to it with the Panamatik keyboard overlay that I already have but so far have never gotten around to use. Some time ago already did convert a HP21 to a HP29C, and also brought back to life one HP25 and a HP27 with Bernhard's ACT.

Thanks everyone for all the information.
