AROS is also the basis of the ApolloOS fork that the Vampire accelerators people maintain to take advantage of their chips' features. https://www.apollo-computer.com/apolloos.php

FTA: “In my opinion, the ASUS motherboard is worth a look. At the moment it is the latest and most powerful hardware on the recommended list, inexpensive and widely available on auction sites”

So it seems the best hardware to run this in is from 2012 (https://www.expertreviews.com/uk/motherboards/51537/asus-p8z...) and can’t be bought in shops.

Given that that motherboard doesn’t have Amiga hardware, what’s holding them back to support newer hardware?

It's cool but damn the UI is ugly looks "old" makes sense

One day I hope to dive into this world too (osdev) but don't have a reason yet.

Edit: looked at ApolloOS link from other comment
