I was very lucky, but it goes to show how proprietary RAM modules - must have some "play" in them to be mass produced for slightly different computers. So that's another unique thing about the Kanga: last Apple laptop to use overpriced, dicky proprietary RAM modules! All Macs after this used standard off-the-shelf RAM modules.

I'm not sure if other Mac notebooks (below the Kanga) have comparible compatibility problems like this - I don't think so ... most models have had the same bus speed, regardless of CPU frequency, unless anyone recalls otherwise!

I've been hammering the Kanga for many hours now, and it's not missed a beat.
