Well, yes it does have a Z2-Slot, and a Video Slot. You can get more Z2-Slots with a busboard for the side expansion slot. You can add one more expansion via the front expansion slot , where the A1000 takes the mem expansion.
But heck, this is a collector's item that boosts your A1000. If the A1000 is just a heap of electronics to you indeed do not understand what makes this thing precious. If you continue what you wrote earlier, the similarily specced A2000 is way overpriced, too, because an A1200 might be brought much cheaper to a a similar spec.
This is one of less than 1000 made special motherboards that embody the spirit of the Amiga. They were a not-commodore-clone made by hardwarefreaks. It was pre-funded by pre-orders from Amiga-fans. It fits inthe Amiga case that made the world's jaw drop, so to say. it even has a special poem written on it.
This thing is all and represents all that is not rational. And for that, I love this thing.
