I would appreciate the pinouts for the Sony VAIO PCG-9G1L laptop, made
around perhaps 2002. The jack when viewed from the rear has two pins
in the center of the round barrel (not coaxial), neither of which
shows continuity to case ground.

Never mind, the two pins are actually a forked single pin and the
jack is coaxial, although the barrel is plastic and the 'shield'
is just a spring wipe contact. The two pins must have been part
of a broken center conductor in the jack.
