The mister multisystem is not an improvement over the de10-nano. It's just an alternative in a different form factor to the open sdram module and the analog io board. You still need a de10-nano to plug into it. It's not the first time I see this confusion but I'm a bit surprised by it because they also make it very clear that "A DE10-Nano is required to operate"
