what's wrong with using it for arcade, old skool games?
Ok, I know I'm coming off as really negative here, but this computer model is a serious tragedy when it comes to performance.
The main problem is it's CPU. It's a 75mhz 603, which was the budget CPU of that time. It's actually the slowest existing Mac to date with a PowerPC processor, seriously, it's much slower than the 60mhz 601.
68k emulation is about as fast as a 68030. Back in the days my friend and I were quite surprised to see my LC 475 (a 68LC040) run circles around his Performa 6200 everytime we tried the older games. Sim City 2000 was a prime example as it took several seconds longer for him to create a random map that just zipped by on my pizza-box. Not to mention how some older games won't play sound under emulation.
It's not a totally lost cause though. If it's games you want then I suggest you keep to the first generation of PPC-optimized games like Marathon. Crystal Caliburn, Looney Labyrinth and Command & Conquer comes to mind as do Warcraft 2.
With Arcade, you mean as in MAME, right? It's possible of course, but you are limited to the really old pre-1990 games. Anything more recent from Capcom isn't even playable on a 7500 with a 604 CPU upgrade, which was my mainstay model during high-school. Truth to be told, there already are good (though not arcade-perfect) ports of games like Pac-Man, Defender and Space Invaders for the Mac.
One good thing about the 6200 is the AV model that came with a TV-tuner. You could use it to watch TV while working at the same time! However, the stock VRAM probably needs an upgrade from it's original 512kb (if possible, I don't know). Default it can only show 256 colours in 800*600. If you go down to 640*480 it manages 16-bit colour which is fine for the TV-tuner.
Another is the infra-red port at the front, so techincally it can be used with a remote: even more TV-goodness!
What more, well it has a CD-ROM that's properly connected to the speakers (unlike some other old PPC Macs) so it's possible to use it as a stereo without hassle. It's also small enough to be used as a simple desktop word processor.
I'd like to suggest that noone uses MacOS 9 with the Performa, it's a way too slow for that. You're going to feel like you were running OS X 10.0.0 again... 8.6 is the limit IMHO, but 8.1 would probably be a better choice, performance-wise.
It's got a pretty shell, but there's not THAT much going on under it I'm afraid.
