Intel Pentium P5, package top

Bottom view, die cover removed.

Closeup shows die with wire bonding. There appears to be lettering along the top edge of the die, near the left.

Closer look at the lettering. 'Pentium Processor' text is visible.

Pentium P5 die text closeup. This may be the best view possible using non-professional camera equipment available in 2010.
The Pentium design team may have regretted adding their initials to the die after its recalled FDIV instruction cost Intel half a billion dollars.
62 more sets of initials can be found on the right-hand edge of the die (not shown).
