Was playing with a 6809 system not long ago and, yeah, FORTH maps really nicely to it. S reg = parameter stack, U reg = return stack, Y reg = interpreter pointer. Inner interpreter is a single two byte instruction (jmp ,y++).
I'd always wanted to play with the 6809 and it really is a slick little 8 bit cpu.
