Got to say Kudos on this, I really look forward to reading more about this! It would be awesome if this gives OS4.1 Classic Users the speed needed to get the most out of this OS and dual booting with OS3.x would give an awesome setup
I'd definately pre-order one and would be happy to pay a desposit now if it helped with developement.
I can also offer my services for testing, being an experienced OS4.1 Classic user with multiple A4000 setups (A4000D RevB/A4000D RevD+Mediator4000D and an AT A4000T) I could test accross multiple platforms
Keep us posted!
