HP-48's display with an unusual(?) stain

[mfleming]

My personal opinion, for what it's worth. I've used the "rip a phone book in half" method on several 48's. Very easy to mess things up, particularly the first time, by bending the inner metal frame or other damage. The reassembled case never quite feels the same as before, in some instances the two halves are noticaby loose. If ever I find a reasonably priced 48SX (inflation. Meh!) I'll try the remove the faceplate with a heatgun/hairdryer approach. A much less savage way to access the heat stakes holding the case halves together.
