Come across a lot of questions and no answers for this, so I thought I'd throw
it your way
Shuttle uses some different resistors on their boards. I think it's a 1k and a
4.1k on the -12V and a 1k and a 2.8k on the -5V, with the same 4.096V reference.
I'd try to verify these values but all of the resistors are right below the
power supply and behind the floppy connector so I can't really see them without
taking the thing apart.
compute in5 (5.1 * @) - 16.79 , (@ + 16.79) / 5.1
compute in6 (3.8 * @) - 11.47 , (@ + 11.47) / 3.8
result:
-12V: -11.89 V (min = -12.63 V, max = -11.40 V)
-5V: -5.03 V (min = -5.27 V, max = -4.72 V)
