I've seen that.  It looks very interesting.  I'm personally not
opposed to using GALs to reduce part count, but I own multiple burners
and I've been working with PALs since 1984.  It's a technology I'm
comfortable with.

That sounds entirely do-able, but it is beyond my skills to engineer -
I could construct it, but I wouldn't personally attempt that as the
sole designer.  I know the 6502 core is done and available, but I
don't know about the 6520 or 6522.
