#Rumor Update
You couldn't use Akiko as-is to replace 8520s. If you brought out all the
pins on an ASIC designed to replace the 8520s in a "normal" Amiga system,
I don't imagine that it'd be any more difficult than any other new board
layout — you might even be able to revise an existing layout.
ASIC is a relatively expensive way to replace the 8520s, though. On CD32,
it went in there because there was going to be an ASIC anyway, and the
8520s could fit in a corner of the chip. Because of the form we now have
the 8520 emulation in, though, we could now drop it into a lot of places.
The systems guys and chip weanies could provide more options and details,
this really isn't my area of expertise.
