"In one of the videos, Elbox said that they are using the MMU to do some PCI related things. There is a possibility to write a software that uses MMU but since it is not compatible with 68k MMU, the existing software won't work. Someone said that such software will be needed (for example for debugging purposes). Elbox answered that they are aware of it but most of the users won't need such thing (since user programs don't use MMU)."
In the video mr. Binek mentions that a new version of mmu.library would be needed to utilise the mmu under amigaOS.
