I greatly appreciate your response, but...
I already knew that. And it's not quite true. Both Forth and Postscript (via
JaM via E&S Design System) drew inspiration from the Stack Architecture
used by Burroughs Large Systems. John Warnock has denied any borrowing from
Forth.

I've got every Postscript book Amazon knows about. I'm looking for info
that's not in the books.

I have a sneaking suspicion that they used a custom Assembler using
something like M4. (Don't bother searching for PS+M4; you'll just find my
earlier question :)
