Am I the only who noticed that the first two pictures both have the orange, Detached Solutions screen covers? TI made those years ago in such a low quantity that they're probably the rarest thing pictured in the three pictures. And there are two pictured!
What are they from? How are they special?
Detacheds Solution is, to a certain extent, some sort of cult/mythical/legendary formerly active programming group, both in the way that they have released some of the most popular softwares at the time (PuzzPack, Omnicalc and MirageOS, for example) and also the fact that PuzzPack comes pre-installed on most TI-83+SE/84+ calculators. The fact TI themselves released DS-themed slide cases is something.
