Never heard of it till now. Interesting, reminded me of my mom's HP-15C calculator I played with as a kid.

Swiss micros sells high quality remakes of many of the HP calculators, with a couple of high end new creations of their own. Works of art and engineering for sure. Not as good as my top end TI for just getting stuff done though.

My dad has a 15c as well. Fond memories there.

Speaking of works of art and engineering, the three HP Voyager series calculators on my desk (12C, 15C, 16C) still work as well as they did several decades ago when they were new. As does the other 15C that I regularly carry around and occasionally drop.

My father only had a problem with the battery leaking in a bigger HP calculator that had these expansion modules. His 15c is also still working since the 80s.
