I figured this would probably be of interest to some people here, too:

I've had this NS DM8200D 4-bit comparator for a while, after posting some pictures of
it to Twitter, Evil Mad Scientist Labs offered to take super macro photos of it for me.
It's just a comparator, but the DIP package is a very early "gold sandwich"
style carrier. What really makes the packaging unique is that the legs are rolled into a
tubular shape, rather than being the usual stamped/coined construction modern ICs use!
Thanks,
