AROS 64bit exist already. I'm sure all AOS variants will follow... hopefully AOS4 does it before PA6T silicon dies. ;-)
Yeah yeah yeah... but AROS 64-bit cant run 32-bit binaries. Even if it could those 32-bit applications are still limited to a shared 32-bit address space. In practise it is not even possible use full 4 GB ram because some address space is required for gfx card VMEM and IO.
