If it's gunna be a serious working machine then I wouldn't bother...
It CAN be done as long as u have enough FAST RAM...
It may be worth doing for fun though

I got OS3.9 up and running on my CDTV just so I could show that it could be done

It was quite a bit of fun getting it on there, and it's still there today 'cause I mainly use it just for CDTV games... But occasionally I'll let the HDD boot up into OS3.9 and have a play
