It is in tolerance - barely. The tolerance for the -12 volt output is 10%.
As far as I know, it's used in only a couple of unimportant places:
1. As a signal level in the now pretty much unused RS232 port where it only needs to drop below -3.0 volts.
2. And as the negative rail in any audio circuits on the motherboard.
It's OK to use this particular CPU.
thx jsc, for the reply !!!
