Perhaps someone knows someone at a suppliers who could identify a manufacturer who is getting through large quantities, and ask them what they are making?

Yes, that was my thought that prompted me to start this thread. I was looking up some ICs in a 1990 Maplin catalogue and noticed that they sold a ZN414-like thing then. I remember it in magazine projects in, say, 1973. Keeping an IC in production for 17+ years for the benefit of home constuctors seems very unlikely!
