I had a 486DX - if I wanted to play an MP3, I had to exit out of everything and run only the DOS player.
Love how people are still pushing old hardware. These are also two excellent demo's on the XT: Area 5150 https://youtu.be/fWDxdoRTZPc?feature=shared 8088 MPH https://youtu.be/yHXx3orN35Y?feature=shared
Somewhere on Usenet there is a post of mine about running it on my 286, but I just wasted an hour trying to find it.

On my 486 I don't remember being able to play MP3s in realtime. I remember having to convert a 3MB MP3 to a 50MB WAV that took up my whole HDD just to play it.
> MP3PC.EXE (73,483 bytes): Got no sound card? MP3PC plays MP3 files through your PC speaker! For some reason I like to make programs work through the PC speaker. Some people still don't know that it's possible to play real sounds through it. Unfortunately, you must run this in pure DOS mode for it to work.

>It uses a 16mips pic (64hz 4-cycle) driving 1K of an 8k dual port ram. This is much closer to the "Reverse Emulation" of the NES that https://www.youtube.com/watch?v=ar9WRwCiSr0 did than playing a movie on the actual device. Using the original hardware as nothing more than an RF output interface is clearly not the same work, though just like in the reverse emulation of the NES, it is still a neat thing. The reason v…

Ken Silverman, creator of the BUILD Engine, made MP3PC.exe that's still hosted on his Utilities page. I'm pretty sure I used this on a 486 years ago and was surprised at how well it worked, though it apparently is picky about MP3 encodings. From the description: > MP3PC.EXE (73,483 bytes): Got no sound card? MP3PC plays MP3 files through your PC speaker! For some reason I like to make programs work through the PC spe…
> It is impossible for the audio to drift ahead of or behind the video, regardless of the video framerate or audio samplerate. How is this "impossible" if the video clock and audio clock are on different physical devices?
The video clock (I assume you mean pixel clock) isn't relevant. The synchronization of video and audio happens on a per-frame basis. And since the frames are clocked out on the audio-clock, there cannot be any drift.
