These are functional after a fashion. They don't exploit
the performance of a precision (stable) voltage
reference . . . and they don't drive the full
constellation of led/incandescent lamps and/or
digital data ports.
I'm working an upgrade of the original AEC9005
LV warn/battery management module that will use
modern surface mount parts and 'package' by
soldering the board to the solder-cups of a
d-sub connector. Surface mount will greatly
shrink the real estate on the ecb. This will
get us more bare-boards per coupon on the low
cost, fast turn prototype service I use. Makes
the individual boards a lot less expensive.
I should have a sketch of the schematic to
share shortly . . . I'm in the middle of
a fabrication project in the mess-making shop
that needs to get done asap . . . but this
ol' dog needs to sit down and rest the
feet from time to time . . . chance to do
some fun stuff and herd electrons.

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"
