You won't be able to run everything, but it should mostly work. The quitkey function relies on an 010+ feature, but some installs have been fixed to work on a plain 000. You'll be limited by your RAM, of course, and there might be trouble with installs that need a 1.3 or 3.1 ROM image (there are some games that just refuse to work on my 600, not sure if that's why).
