That is a bit of a surprise--in my experience it
takes very little
code to support Forth on any processor--that someone would build a
dedicated chip for it is unusual.
There are actually quite a few Forth processors. Charles Moore himself
designed half a dozen or so. The RTX-2000 series is a descentant of his
Novix chip. Check out GreenArrays for his latest work.
There are also some FPGA designs out there. The J1 seems somewhat
popular.
