So, a sort of "Turing Test" for the Amiga. ;-)
"You look down and see a tortoise, Amiga. It's crawling toward you... " (maybe to obscure a quote?)
For myself my apps and games are fine on an 030, but I watch a lot of demo's, so i'd really like some 060 beef. And RTG of course.
To my mind, if it runs most Amiga software, and there is no other underlying OS getting in the way, then it's pretty much an Amiga.
