DB9 is still used on for MIDI on electronic instruments, though some manufacturers are moving to doing it with a TRS 3.5mm plug since it only uses 3 pins.

I had a mouse that plugged into the serial port, but my first computer was a Commodore 64.

Yeah, I have a bit of midi stuff with DB9 connections. It's a fine connector!
