ooh. things like this can be hard to open, and can also snap if not careful, it will require some significant amount of force in the right direction

Yep, pull hard.

Also be sure to keep track of every single little screw. I've already lost one :P

And when you take the keys out, you can wash them (they're just pieces of plastic), but (as you know) make sure you dry them!

Oh, and this is a good opportunity to switch around some stuff ;)

What are these "clips" on the side of the case that you speak of? My 83+BE has been having problems with it turning off inexplicably and me having to bang the bottom of the calculator against a desk to turn it on again. I tried to take it apart before, but my dad looked at the screws on the back and found that they weren't screws: they were rivets, which are impossible to take apart.

Also, how do you preform a RAM restore using DoorsCS7? I didn't know that it could do that.

And additionally, regarding DCS7's size, does anyone think it would be a good idea for Kerm to provide an "abbreviated" version with the Basic libs removed, so that it only takes up 32K? I don't have much space for apps.

It can't do that. z80man is probably saying that DCS allows him to keep everything in archive, so that there's nothing in RAM that can be RAM cleared.

You can take them off with a small flathead screwdriver. If it's the right diameter, it'll fit in the hex head well.

And by "clips" I mean when you open a calc, even after you take the screws out it's still stuck together (as protection, I guess). You have to pull hard to get it to come apart (after prying a piece open with a flat blade).

Next question: what is good for cleaning the keys?  I don't think we have the isopropyl alcohol the instructable was talking about :P
Would plain water work?

Don't use plain water. Plain water is electrically conductive if it has any impurites at all, a recipe for disaster. Isopropyl alcohol can be purchased in the form of Iso-HEET, an antifreeze available at any gas station. I don't believe it conducts electricity, but I do know it is flammable (I know about this product because we burned it by the bottle at Scout Camp. :) )

Yeah, I'm not exactly about to screw the stuff back on while it's still wet :P

Just use plain water and a toothbrush or something to get grime off (assuming you're only cleaning individual keys). It works.

Make sure it's dry when you put it back together, of course (but then you should know that :D).
