The reason for the asking about the SRAMs on the bottom or not, if any
imagery of what you see is not of the same time, you won't have the
same thing inside.

They are totally different. The SRAMs showing is a redesigned part,
and was made to use off the shelf, tested SRAMs for cache vs. stamping
their own integrated cache which was a major source of failure, RMA
wise.

You may then also just try applying heat to each lead for 4 seconds or
so, too. But what you will find is that it's a ceramic/hybrid with the
leads soldered on like a SIPP.

The older ones tended to be easy to dig into, the later ones were not
as easy. As you say, more potted, less rubbery.
