I bought an Alps KPX-17 keypad. However, it requires a floppy drive and a parallel port. Instead of buying an adaptor and floppy drive, I was thinking of just hard wiring the thing. The only problem is I can't get it open. As you can see, the screws are partially hidden underneath the edge of the case, and so can't be reached by a screwdriver.
Here's an angled show actually showing them:
And there are no screws on the outside. Just this square hole:
The case seems to be held together by adhesive.
So, how the heck do I open this thing?
