If you have computers in your game, you might find use in these two different sound effects I recorded a very long time ago. Though they are 8-bit WAV files and monoural, the sample rate of 50,000 Hz helps. Both sounds have had their "volume" amplified to double, however. The first one is my current floppy disk drive (when I say noisy, I mean noisy). The second one, though much bigger and longer (same specs: 8-bit, mono, 50,000 Hz), is loopable and quieter. The quieter one died and I've replaced it with a backup which was very noisy. Hopefully you'll find some use in them. This way, you can choose your quality for MP3 or whatever. I'm completely unfamiliar with OGG so I don't know anything about it and it's specs.... The files here are ZIP files. Unzip them and you have the WAV files.

Edit: I could try to get 16-bit WAVs, but it might be a while.
