That’s what I thought at first, too. The DIN connector on the right being the power supply connector, and the DSUB9 being the joystick port (one of them).
BUT: In every C64 model I’ve seen, there is the power switch right between the DIN and DSUB9. Which, in the photo, is not. So it is not a C64.
It could still be a joystick port, as DSUB9 was the most common joystick port form back then, before the DSUB15 commonly used on PCs for analog joysticks were a thing. Actually, serial ports back then used the DSUB25 connector. DSUB9 “reduced serial ports” came later.
Another common use of DSUB9 was for VGA before the three-row DSUB15. The DIN connector was commonly used for audio but also (composite) video.
My personal guess is that the bottom picture shows the video output of a computer, with the DSUB9 being an old-style VGA and the DIN being audio+composite video.
