Indeed.  Is there a language definition somewhere for those
calculators?

Neat!  The appeal of Forth for me was the "bootstrap with only bare
metal" scenario but that's primarily an historical problem these days.

Probably due to the uses to which each is put - scheme, being smaller,
makes more sense for embedded applications and performance tweaks are
more critical there - applications are still hardware limited.

Cheers, and thanks!
