Temperature Sensors

[Guest]

I'm in need of some Dallas Semiconductor DS1620R (the R version is no longer available) temperature sensors that most likely were installed on motherboards of 200MHz to 600MHz CPU vintage. Does anybody know what specific motherboards have this chip onboard??
Does anybody have any old motherboards with this chip?

This DS1620R should be fairly easy to spot because it only came in a 16 pin package...
