Wow... you've done so much work on this that I'm amazed. I've been
reading up on the F8 Programming Guide, and so I should be able to
start working on some things as soon as DASM is ready and as soon as I
talk to Sean Riddle about some stuff graphically and about the Channel

Thanks for all the wonderful work you've been doing, Thomas!
