     More will come later on;)
     The idea about multiprocessing I had was like this:
     040 -> Fast Ram
     030 -> Rest of the Falcon
     Ergo, multiprocessing! If the 040 tries to access the rest of the
     Falcon, it halts the 030. Thus we get this situation:
     040 Fast Ram
     030 \-> Rest of the Falcon
     There should be signals that do this automaticly. This way the 040
     gets the highest priority...
     The biggest problem is that we need to initialise both processors,
     which actually means two boots! If we could control the 030's reset
     signal and control the address from which it boots, then it all would
     be much easier. But we'll see what I can do...

Wheee! How did you do that!
Tell us more! Coool.

Multiprocessing like the BeBox ion your Falcon! I can't see how it could
be done though.
But the info on how to switch to the 030 with the AB040 still fitted is
very much wanted indeed. Not that it's realy needed, but it would be cool
