Interesting book. Not sure how it might apply to what I am trying to do though. While I haven't used Forth for quite some time I did use it extensively for a number of years. This included bootstrapping in a couple of small processors. The process is surprisingly simple. From memory, a significant portion of the work was having to write drivers for the various I/O devices needing support.

I have a number of ideas for the minimum I/O set to support initially. Of course, this could easily be enhanced through expansion ports.

I am trying hard to limit the scope of the project. It's far too easy to complicate the heck out of it.
