There’s a similar chip that makes a door chime ding-dong sound. M581A

the part numbering in the datasheet makes it look like there were dozens of different songs at one point, since they’re numbered like -001, -002, -019, -068. I wonder what their full catalog looked like?

whips out a AA battery and a piezo speaker.
yeah i listen to music on tape
All I want for Christmas, is…
