How does one open up an HP-27s
#1

I see no screws and the sides look to fragile to pry open without leaving marks. So, what is the trick?

Thanks

#2

Look around the MoHPC for my article on "Pioneer Internals" (I don't konw how to hyperlink from here). It tells how I took a few apart. It's not impossible. If you decide to take the LCD out, that's the most touchy part of the operation.

What ARE you taking it apart for, by the way?

Sorry, but I just noticed this response. The LCD has dust and grit underneath and the display is getting difficult to read. I'd just like to clean the display.
