It just so happens I have one of these on my desk!
Look carefully and you will see that the hard plastic top surface of the
calculator - where the buttons, display, solar cell etc, are - overhangs
the soft vinyl just a little. Put your fingernail or a guitar pick in
between the vinyl and the hard plastic and slide it back and forth.
On the left - the long side that is not next to the hinge - there is one
plastic locking tab in the middle - just north of the "SHIFT hyp" button.
On the bottom, there are two tabs - one between the 0 and . keys, and
another between the = and M+ keys.
The top has two tabs, in the same places as the bottom.
The right has one tab, in the same place as the left side.
The guts/works of the calculator are attached to the keys, and will come
up once you've released the locking tabs. The back cover - what the
guts snap into - is white plastic and (mostly) five sides of a box - it
seems to stay in the wallet.
The flex cable to the membrane keys in the right side is about 30 mm
wide and attaches to the guts just behind the divide, subtract, and M+
keys. The joint is covered by a removable plastic piece - I didn't take
that off, so I don't know if it's soldered, or has a connector, or what.
I took a few photos, available at http://imgur.com/a/h6kWJ . One of
them shows the left side locking tab, one shows the bottom locking tabs,
and one is a view of the back of the guts. You can just about see the
flex cable on this last one.
Back in the day (late 80s, early 90s), these Casios were just the thing,
if you couldn't afford an HP. I had the FX-115 in high school and got
the FX-451 later on.
