Analog Gauges / Air-core meter

[Robert W. Hughes]

All of the later model Chrysler products use these gauges for all
displays. My 91 Voyager has 6 gauges in two (big and little) sizes and
the actual meter mechanism is identical on all of them. They are driven
by the body computer (a 68HC11) over the CCD bus and the panel has a TI
bus receiver chip and some sort of gauge driver chip to drive all of
them. Even the speedometer and the tachometer are included and all of
the gauges can be unbolted from the circuit board.

It would be worthwhile to find a panel like this (any Chrysler product
of this vintage with the gauge package as identified by the presence of
a tachometer) in a wrecking yard for experimental purposes.
