Yes but I'm not sure they didn't just take a conventional CPU and optimize it
for Lisp. That is no more interesting than optimizing a CPU for Java or
Python. I'm looking for something more radical.
Or...barring that...I'm wondering if many have written a small Scheme-ish layer
on top of a CPU and written <insert favorite language> on top of THAT.
The challenge you are looking for is to build your own CPU. This can be
done without having to develop shadowmasks and worrying about quantum
effects by using a Field Programmable Gate Array (FPGA) such as those
sold by Xilinx or Altera. The FPGA is programmed in a high level
language (well, high level compared to laying out transistors) such that
you work with either individual gates or blocks that perform some
function. Take a look at Open Cores <http://www.opencores.org> to see
some of the things that can be done.
