I bought powerbook G4 3.5:
http://www.everymac.com/systems/apple/powerbook_g4/specs/powerbook_g4_1.0.html

Otherwise seems ok and speedy with MorphOS, but no sound. (worked ok in OSX)

(perhaps a list of supported HW needs some mention that audio does not work on powerbook 3.4...3.5 models???)
"On this page, you find a list of hardware that is directly supported by MorphOS 3.x."
"Computers"
"Apple PowerBook G4**"
"* * - Only models with a Radeon graphics chip are supported."


Any info if work is done to enable audio on those low end PowerBooks? (essential component of any "Amiga")

(I imagine it might be minor issue in i2s implementation, if someone needs tester for i2s fix for 3.5 powerbook, send me pm)

UPDATE:
Some things that I've learned: these old powerbooks use ADB interface for touchpad and keyboard connection, because of that, the touchpad is not detected properly and keyboard does not work that nicely (ctrl+apple+apple does not do reboot). Also battery info might not show up correctly.
(anyway, I bought this for eur50 with 1G RAM and new DVD drive + spare battery and so far I have enjoyed it greatly, I will register OS for this and hope to see fixes for audio and ADB stuff one day)
