I was looking inside my ProLog M-900 and noticed a gold and
ceramic chip labeled "INS4004D" socketed next to two i4002s.
Does anyone know if National Semi second sourced the i4004?
It also has the number "530" on the bottom which I suppose
is a lot no.

For those with GUI browsers, here is the best I could do
with my camera:
