Have morphos installed on a PowerMac G4 1GHz DP quicksilver. With a little help here and on Morphzone I've installed an SB live card/pack ultimate and grunch, just waiting on my USB card (taking forever!) so I can have more than two USB.
About a month in using Morphos the OS works great, but haven't used it for awhile have been tinkering with my WinUAE box. Can't wait for MorphOS 3.0.
Anyway welcome to the club :-)
