Prop calculator

While dismantling some PABX for relocation, I came across a box of calculators that were obviously made in China. It was thrown there but the staff because most of them were not working or had leaking batteries. When I took a second look, the design really caught me since it has the right shape to do any prop. Yeah, and you know what happened next, needless to say.

Trust me, this was a working complete set when I was about to
take some pictures. I accidentally dropped it and the thing split
into two. Since the plastic was so brittle, the two pillars holding
the screws broke off. But upon closer inspection, there were four
plastic clips so I can snap the two cover back without worrying
about it coming off again. The funny thing was, inplaces where
they do not use glue, they used screws and vice versa. Weird

And another thing is the keypad membrane. Usually it is made
from those silicon/rubber mats with conductive carbon tracks
but this is different. Its made from a slightly tougher supermarket
plastic bag material. Must be due to the cost of the extra screws

And here you go, the whole electronics

With everything gutted, now, do you see the potential?
