HP-45 Green LED display
A few years ago there was a prototype HP-45 for sale with a green LED display. Does anyone know what happened to this? Just wondered if there were any photos of it floating around the internet, as hadn’t seen anything in the museum.

The link to a certain auction website in the archived thread is long dead, and despite a request from a fellow member, it seems like the seller did not share photos with the museum.

There seems to be an extract of the auction description with a couple of photos on a Swiss website, Calculator Nostalgia, just wondered if there are any more detailed photos, e.g. of the insides/ differences with a standard HP-45.

I’m also curious as to whether there are any other green LED calculators floating about (not vacuum fluorescent displays VFD, which seem to get misappropriated as LED displays).

Not an HP calculator, but there is an YouTuber Calculator Obsessed, that has shown a calculator with a green LED display (not VFD), but is labelled as a mystery calculator, and looks a bit home made/ modified, although it looks like a proper 9 digit seven segment green LED display. Curious to know if any others have seen this or where the display may have come from/ been used. Not sure if any other use case other than for a calculator or similar device.
