ACA500 does not allow any other expansion than a chipmem expansion.
The lower 68000-adapter will block the 86-pin port to send a clear message: Nothing allowed here.
Further, the 68000 socket will have to be empty, otherwise the mechanical mounting concept won't work.

It's why I ask (post #106), why not using the $200000-$9FFFFF memory space instead to get 4/8MB fast RAM on the ACA500 board to avoid to buy the ACA1220 if not needed.
(except if the ACA1220 expansion use it as 16x8MB back-memory or virtual address space)
