[time-nuts] TAPR Oncore M12+ kit

after carefully crafting the suggested db9mf cable (with 16vdc on 7 & 8+) i
powered up, but no green led...

the db9 to chassis seems ok. but am still engaged.  there is no voltage
across the backup battery (the holder seems slightly bent).

the lack of a schematic for the mobo is a big problem.  any documentation
on the 10-pin interconnect to the m12 would be nice.

i guess this is what you call a slow start...
