Texas TI-34 solar scientific calculator from 1987

Thanks jebem for this teardown, I just got a hold of the 2nd edition of this TI-34 (blue buttons instead of red); it's in better condition, but far from perfect.



One thing that got my attention was the fact that the front cover on yours was metallic. The 2nd version I have is just a plastic front cover and even some of the ones I've seen online with the red buttons appear to be plastic as well (maybe they are just much better condition?).

Also my one has a 10uF Electrolytic @ 6.3v instead of the 22uF, which is a little odd as I've seen the links at datamath and they seem to still be 22uF in later versions.

Really love the contrast on this display, and it's low-light performance is really good. Persistent engineering mode is nice plus on a pure solar-powered calculator.
