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
between the two contacts. The only markings I see are "Japan" and
"3015-5" on the back and "C-27-09" on the side. My suspicion is that
they are incandescent but I haven't found any information on them yet
using Google. Does anyone know what these things are called?
