I believe the email he was responding to was one I posted in 2002. The
regulators in question are Fairchild uA79MG and uA78MG. They are
4-terminal adjustable voltage regulators with a package style similar to a
typical TO-220. The actual Fairchild part number of the regulator that I'm
still hunting for is uA79MGU1C.

I have the Fairchild voltage regulator databook and responded to the
poster off-list. If someone has an electronic copy of the datasheet for
these regulators, speak up as it will save me the trouble of scanning the
relevant pages from the databook.
