I bought a FAULTY 1982 Casio calculator | can I FIX it?

I picked this up from eBay years ago. It's a non-working Casio LC-786 credit card calculator thing. It's been that long, that I can no longer see any of the details, so I have no idea what's wrong with it. Let's take a look, and see if we can get it working again! Hope you enjoy! Steve PS. I'm not an expert in repairs at all. I do this for fun, and it may not be the best or safest way to go about repairing broken stuff. I'm pretty good at melting plastic though. Please don't copy me - I'm an idiot.
