That, my friends, is a sound card. And the port you're referring to is a 15 pin joystick port.
Back before USB was commonplace, PC joysticks used that 15 pin connector. Joysticks then didn't have any on-board electronics, they just conveyed the analog potentiometers and button presses directly out the port (which is why it has such a high pin-count.)
Why are these ports on sound cards? Well, joystick ports were never especially common on PC motherboards in the 286 / 386 era. Some machines had them, but as often as not you had to buy a joystick-port card. So it was a natural value-add for the soundcard to have this built-in, as it was safe to assume that anybody buying a sound card was also playing games.
This being the case, the manufacturers also quickly realized that they could piggyback a MIDI stream onto the same connector, so for those who wished to interface their PC an an external MIDI instrument (anything from a simple keyboard to the coveted Roland MT-32) you could just buy a little external dongle and plug it right in.
Of course, MIDI interfaces weren't well-standardized at the time, so if you wanted to play, say, a Sierra game with an MT-32, you had to use an MPU-401 interface.
(How the hell do I still remember this stuff?)

Well, if you're referring to the name "Analog Devices", that is actually a very well known company which started out making high-precision analog stuff, and these days also builds some top-notch DSP chips which are optimized for audio / video applications.
I do believe you are the first person I have ever heard use the correct terminology for a D-sub connector in my life (eg: realizing that "DB" refers specifically to the 25 pin variant, and that what we commonly call DB9s are properly DE9s.)
We are both nerds.
My buddy has one lying around that weve been wanting to use for something.
I wonder if anybody still makes them solely for the purpose of being a simple DIY interface for n00bs like myself.
You can still find USB gameport adapters. Not sure I've seen a PCI one in a while.
Lots of vids in here… sometimes I start watching one and soon decide it sucks so I hit pause and move on to the next one. Yet the paused vid naturally keeps loading, which obviously slows down the subsequent vids.
Is there a way to stop the loading of an embedded Youtube video without reloading the page?
