Pretty awesome stuff offering the ability to use classic Mac software from the 80s in browser. These sorts of efforts are so fantastic as history lessons. As the decades slip by, it will be harder and harder to get an accurate picture of how computer technology evolved, and websites like these seem like an obvious answer to avoiding losing these integral parts of our society.
It also brings to mind why its so frustrating that Nintendo is left holding all the cards for their classic IP. The games from the NES era are a huge part of so many people's development which is why so many of us are devastated with the flippancy they have demonstrated regarding the now defunct adorable little NES classic. I've purchased the original Super Mario games so many times over, and yet there's no indication that I'll actually be able to play those games still 10-20 years from now.
