["Paul Blogger" -- I swear, it hadn't even occurred to me! I'll have to start one.]
My email address has gone through several iterations over the years, and is always "mangled" on this Forum. Take "NoHormel" (i.e., no SPAM) out of the mailto: address above, and you'll reach me at my current ISP.
They're melted-over heat stakes, just like the ones you drilled. Their orientations are reversed, however, and the heads are hidden beneath the metal faceplate of the keyboard.
You may wish to read also Article 199, "Increasing HP-42s Memory to 32k" for more info on taking Pioneers apart.
Also, look at the "internal pictures" of the HP-32s and HP-42s in the Museum articles for those calculators.
I just grab the two case halves, keeping clear of the internal PCB, and rip 'em apart. It's worked every time.
Good luck, and contact me here or via email if you need more info.
