An amazing site; thanks for posting it! According to this site, they are
called Minitrons and they even had the datasheet for them. Thanks!!!
I have eight
NOS seven segment displays in a 16 pin DIP package. These
displays have a glass cover and each of the segments have a wire running
look around here as they have pictures of several older display devices.
