Feh, the "old" HP12C that I got for $15 is only 30 years old. My HP16C
is 35 years old. The innards between the two are completely different.
My HP16C comes wrapped in antistatic plastic and has what looks to be a
hand-wired axial resistor and a "blob" tantalum cap hand-soldered in
near the battery holder. The display is on a separate board connected
via a flex cable labeled "HP Sheldahl USA 1130-0504.
The 12C is all on a single PCB, with no ESD wrap. Miles apart.
So it boils down to finding a REALLY old 12C and hoping that it's
compatible with my 16C in terms of parts or putting everything back
together and buying the Swiss clone, which will, after all is said and
done, set me back $200.
I don't fancy that there's much hope in finding a 35 year old 12C for
sale at a reasonable price--and the display will still be very old.
