Just a heads up - the (sometimes controversial) Apollo Core 68080 is
perhaps getting an (available) MMU too now, and one of the goals is that
it will be compatible with "Linux / BSD".

https://www.gofundme.com/f/memory-management-unit-mmu-for-apollo-v4-series?attribution_id=sl:a707b374-307b-4388-8636-37c91d0613df&utm_campaign=pd_ss_icons&utm_medium=customer&utm_source=copy_link_modal

A bit about progress is here:

If this materialize, I might just get a V4 standalone solely to run Linux
and/or NetBSD, whichever will work best.
