How to get 80s look and sound?

So this is more of a question about the audio side of things as I already know how to make animations look like they are from the 80s through after effects but am open to suggestions on how to do it in Toon boom.
Any way I’m wondering how I would achieve a believable 1980s sound using free programs such as Audacity. The sound I’m referencing is these two videos
I think they are a little distorted and have more bass to them but I don’t study sound design. So yeah just wondering if anyone that is reading this has worked this out yet and are willing to share some knowledge for the rest of us nostalgic animators.

Good sound quality.
