Aurora DS17
Here's a most unusual calculator that I just received from a fellow collector (thanks, Dennis!) It is just one of those plain vanilla 40-step programmables on the inside, but on the outside! "Hybrid keyboard"? Just who on Earth comes up with an idea like this?
And it's not a very well implemented idea, unfortunately. The lower half of the keyboard is attached to the main PCB using a dreaded heat seal ribbon. Unlike that heat seal that connects the display, which is thankfully still functional, this one isn't; much of the lower half of the keyboard is dead, or nearly so, and my attempts to repair the heat seal connections were not particularly successful. Maybe one day I'll try and replace it with soldered wire (though I'm worried that the flexible circuit that is part of the keyboard may not be solderable); until then, at least the π button works, so I was able to take a scan of the calculator just the way I like it!
