    Does anyone manufacture one of these with built-in autoconfig and 
decode logic?  I used to have one of these (on an older computer) that 
made prototyping a breeze - just use the existing decode and interface
logic, and plug in your new stuff.  

    On the other hand, how do you build an autoconfig block?  I've read
the A2000/A500 technical reference manual discussion on this, but I
don't have a PAL burner.  They give equations for these suckers, which
leaves me out in the cold.  I suppose I could look at the equations and
figure out just what is going on, but I don't have that much time.

    Ideas, comments?
