This is super cool- Forth seems like a perfect fit for the platform.

  Yeah... RPN et al... :)

    Though famously (I believe) it was HP calculators that were known for reverse-Polish notation.

      That's the joke, I imagine. RPN is Forth-like in that they're both stack based. Their 28/48/49/50G line shipped with RPL(Reverse Polish Lisp) which was heavily inspired by both Forth and Lisp. Very weird language but I always enjoyed programming those calculators. The ancient HP41 and HP71 did have Forth interpreter ROMs available.
