Thanks, that's exactly the detail I wanted. I notice you have added a new line enabling the lba-48 property. Can this line be considered optional and be omitted from the patch if …

I have a few of those, but all third-party. Never knew Apple made their own! I use one connected to my Centris 650, with one port connected to an AirPort Express acting as a Wire…

yup, had one in college, used it to share the single ethernet port in my dorm room with my Supermac J700, IIci, II and my roomates powerbook 100 w/ a SCSI/ethernet adaptor.

Huh, must have missed that when I posted it. There might be a way to use the classic version of IPNetRouter, since it supports MacIP.

There used to be arguments among memory upgraders about whether to use sockets or not. There are some 128K boards which just don't have enough juice to drive the extra capacitance …

I just went and bought a new screen for my PowerBook G4 today! Now all I have to do is wait 3-4 days. Finally, I'll be able to use it as a laptop, except I don't have a battery…

No, they don't all have working batteries.. yet. I have a whole stack of macs, I have been collecting them for years, due to the fact many that I bought had varying problems with …
