Actually, Elektor have been rather better about this recently, and in a 
lot of cases the _source_ code for the microcontroller firmware is 
available as a free download from their web site.

Alas, in some cases (often for the projects I am most interested in :-(), 
this is not the case, often becasue the author gets a royalty from each 
pre-programmed chip sold.

I suspect the reason (not an excuse...) was that they made money selling 
pre-programmed chips. Certainly when you boughht the pre-programmed chip, 
it came copy-protected.

No, and as a Forth (and stack based languages in general) lover, I would 
be interested.
