First off the tech doesn't go that far back nobody is using a TRS anymore. And second it's more of a retro vibe not an attempt to recreate the exact tech. I get why someone like you can't understand this concept. It's mainly because you're too logical and intelligent. You're basically a savant with a mind similar to a super computer, you're too logical to fully understand stupid people like me.

Let me explain what's going on. This is just low IQ people like me having a sort of appreciation for retro vibes. High IQ people like you likely are too efficient and awesome to sink to this kind of base cave man behavior that has no logical point. Pay no head to us, we're beneath you.

And since when was RISC-V retro? Calling RISC-V fantasy might be accurate. I fail to see how everyone shifting to an open ISA benefits the people. Saves chip designers a dollar on licensing sure. But the RTL is still closed for most RISC-V that gets tape out. So you have no clue what it’s doing. “open”. Sure.

Have you heard of pixel art? It's a form of art that appreciates the retro aesthetic. I don't think it's your thing. Your brain is to big for such simple minded behavior.
