This would result in the following configuration lines:

label in0 "VCore1"
label in1 "VCore2"
label in2 "+3.3V"
label in3 "+5V"
label in4 "+12V"
label in5 "-12V"
label in6 "-5V"
label in7 "Stdby"
label in8 "VBat"

compute in3 ((6.8/10)+1)*@, @/((6.8/10)+1)
compute in4 ((30/10)+1)*@, @/((30/10)+1)
compute in5 8.228 - (@*2057/400), (8.228 - @)/(2057/400)
compute in6 8.777 - (@*1257/400), (8.777 - @)/(1257/400)
compute in7 ((6.8/10)+1)*@, @/((6.8/10)+1)

Negative voltage limits look rather suspicious to me. Ruik, can you
check again? I'd expect it the other way around, i.e. VAL*K - Vref, not
Vref - VAL*K.

Other formulas are standard so obviously correct.

Doesn't make much sense to me.

A.k.a. 2's complement, i.e. standard.
