Hello, I'm trying to play some old games that don't work properly (no sound) on my powermac g3, especially the game NetTrek (avaliable for free at http://mac.the-underdogs.org/index.php?%20show=game&id=98) among others The powerbook duo 280c seems to fit the bill nicely, since I don't want to take up room with a huge desktop just for a couple of games. From a post on comp.sys.mac.games: "A number of games "broke" outright when the original AV Macs came out for two main reasons: they didn't have the old sound chip the other Macs had, and they used the new SoundManager 3.0 (in their ROMs) to handle sound. ALL the new Macs -- the PowerBook 500 series and the PowerPC-based models -- now share this problem" I was wondering if anyone knows if the powerbook duo 280c has the old or new sound chip. If you happen to have run netflix on a powerbook duo 280 with sound, it means it has the old sound chip. The website http://mac.the-underdogs.org has many old mac games that are "abadonware" and avaliable for download. Thank you so much for your help! I really appreciate it! Here's a link to the comp.sys.mac.games post with a list of all "broken" games. http://groups.google.com/group/comp.sys.mac.games/browse_thread/thread/1ae01c346bf6b364/3653eb0813728e2d?lnk=st&q=%22MAC+INCOMPATIBLE+GAMES+LIST%22&rnum=2&hl=en#3653eb0813728e2d
