One class of stack machines was developed at MIT: the Lisp Machine.  Although
the hardware of the processor is not totally stack-oriented, there is a stack
cache (known as the PDL buffer), and the microcode supplies the (mostly)
stack-oriented instructions.  The first machine was CONS; then came the CADR
(of which there are quite a few at MIT and other places); now there are the
3600 (from Symbolics) and the Lambda (from LMI).

Also, there is a computer course here that explores a hypothetical stack
machine which could, in theory, be built.  I don't think anyone has ever
tried.
