Yeah,  but that's *way* too closely coupled for comfort for a lot of uses...

I suppose that would be useful,  if you had need of two chips running the same 
code,  and if it were fairly re-entrant.  It would require some care.  And 
with the amount of junk I have around it's not a big deal to me at this point 
to just have another eprom and ram chip in there if I need them.

Are there particular advantages to this approach that I'm not seeing?
