Yeah, I love these machines. I'm just sad about some though because in the moment I forget what my computing needs are and such and I end up buying/selling stuff that I do or don't need and then I end up going through that vicious cycle again.
For instance, my first PPC machine was a 12" 1.33Ghz iBook G4 with 1.5GB RAM and a 60GB HDD. Awesome machine and everything worked perfectly (I got it after having to sell my 2009 iMac for financial reasons). After that I got a 14" 1.42GHz iBook G4 (that was mistreated and I had to fix it even though that turned out to be a temporary repair job that ended up in a non-functional FW port, and then a failing KB).
I then acquired 3 iBook G3s in a trade plus a some of none from another member here (which is one of the ones that you got) for a PowerMac G4 with a display KB and mouse that he has now turned into a beast of a machine.
My current one I received from another MR member for free and it works like a charm. Well the HDD was failing but 10 years is pretty good for an original HDD in an iBook. It now has a new HDD thanks to the same guy that got the PM G4 from me and now it's rolling along wonderfully and it's all set to go!
Ah yes, eyoungren is a very nice and knowledgable guy. He helped me get Leopard running properly on my G5. Check out some of the UI stuff he suggested in my guide, it may help alot with graphics!
How is your other two G3s running? I am in the process of rebuilding the 600 MHz's logic board and fixing the display assembly on the 900 MHz
