The SX32's mem must be outside the ZII space since it's >8MB. So there's a good chance the FMV might run in parallel - as long as connecting multiple expansions is possible at all.

I guess the expansion slot is somewhat like the local bus slot on A1200/3k/4k - so it's probably necessary to hand craft the adapter for the specific expansion modules to be connected.

Well the SX-1 had no special handcrafting to run both the FMV and the SX-1...........it just had a loopthrough for the FMV


Then how do you know the loopthrough has not been specifically adapted for the FMV?
The point I was trying to make is that it may not be enough to build a simple two-way adapter with a trick or two to split up lines that cannot be shared. If you're very unlucky you may get problems that can't be easily overcome (timing, missing arbitration, ...). I've got no CD32 schematics, so I can't tell.
