The whole 48/49/50 series covering 1990–2015 has that equation writer functionality, or in other words: every RPN graphing calculator.

Good point.
Still a niche within a though. They weren't that common in the wild like the old HPs were. I knew someone in the engineering program at Texas Tech with a 50g, but never saw a single engineer or stem major at my school with one. They had them in production for awhile, so they're out there (logically speaking), but they've got to be a big outlier.
