We have a 7 segment AC powered alarm clock by Panasonic from about 1980. It still works, but the labels on the buttons have worn off, and we have to make sure we know which button to push to set clock time vs alarm time. It's the oldest still working vintage technology in the house. There are some Panasonic stereo components in the attic from about the same time, but those need to go to recycling.
