This book is pretty much an explanation of a Forth implementation.
Not too bad, but it helps to follow along with some source code.
Fortunately, the FIG has much of the old source available to peruse:

Of particular note is the uninspired 6502 implementation of the inner
interpreter and the sweet 6809 implementation (look for the NEXT label
near the beginning of the listings).
