@dosnostalgic Reminds me of the very first Linux system I used, Speaker Doom. You unzipped it into its own directory and then ran a DOS command to boot into its ZipSlack-based environment. It contained a variant of Doom for Linux with a PC Speaker driver, which output PCM sound effects through the speaker, slowly. It was a pretty neat hack.
@bthylafh Ooh. I gotta check that out.
