I think you mean a Quadra 610. That's a computer from the good old days when Panthers and Tigers were big cats you could see at the zoo. I think you'll probably have system 7 or maybe system 8 installed. If you can get up to 8.6 that's a pretty good OS to have, but your machine may not handle it without a lot of RAM. I think the most you can put in a Quadra is 68K (64 in the expansion slots, plus the 4 you have on the mother board) Finding software for that mac will be tricky now. Your best chance would be to google "Quadra 610" and see if you can find a site dedicated to old macs where you can download some software. There should be one out there somewhere. Here's one to start you off: http://www.68kmac.org And this page has info about your mac: http://www.68kmac.org/db/viewspecs.php?model=Quadra 610 Good luck PS For games, you might want to look at macMAME. You will need to find an old version of it somewhere that runs on your mac. It is a game emulator that lets you play the roms from the big arcade machines from years ago (like your mac!). Stuff like Space Invaders, Galaxians, Donkey Kong, Pac Man...
