If you add the extra circuitry, you could replace the 3.5 mm jack with a single TRS one and wire it the same way it’s wired on the +3. If you don’t want to bother with all that, you can just buy a generic cassette adaptor. They’re cheap and work well.
If I remember you made a video of this using something called a Schmitt trigger?

Nope. Definitely wasn’t me. Perhaps you’re referring to this video from Joules per Coulomb:
