I think that's a really interesting question.

I can't speak with authority but I believe the TI-30 SLR+ predates the TI-68. It has a slide-on cover. I'm betting there are even earlier examples. I thought maybe the fx-7700g but that came out after the TI-68.

The TI-68 is one of my favorite calculators in terms of form and function. It was no longer in vogue by the time I was old enough to have need of a scientific. As Eddie alludes to, the displays seem to be delicate and of the three examples I've laid hands on, all three had issues. I was able to restore one of them to full function using a heat gun on the LCD ribbon connector. It's anyone's guess how long that repair will last.
