need an unoptimized Forth :)

For educational purposes, I need a Forth for i386 coded
straightforwardly, preferrably for Linux.

That is,
see dup
must show
code dup
  pop eax
  push eax
  push eax
  next,
end-code

and see @[EMAIL PROTECTED]
 should show something like
code @[EMAIL PROTECTED]
  pop eax
  push [eax]
next, end-code

Ability to use variable names as operands is a plus, e.g.
variable MYVAR
code xyz
  mov eax, [] MYVAR
  push eax
....

The closest match is F-PC, but it's 16-bit.

(Forth is the best user-friendly interface for Assembler)
