alt Hacker NewsNice, there’s also a great in-depth article about an album driven entirely using the primitive PC speaker. The whole COM file comes in at around 40 KB, so you can copy it onto an old machine and run it. Some of it you'd swear you're listening to a SID chip~
Note for the audience that COM files were limited to 64 KB, thus not much left and naturally it was all done in Assembly.
