Okay,
The first 512MB RAM chip was bad... So I had to order a new one. (Made SURE it was new rather than a 'pulled' memory board.)
Then I had to search and search and search for a set of OS X 10.4.0 in CD format rather than the far easier to find DVD disc.
Well, as of today, my now-640MB RAM, G3, iBook w/10GB hard drive and 12" display *IS* fully upgraded to OS X 10.4.11, Safari 4.1.1 and iTunes 9.2. It accepted the iTunes Producer 2.1.2 and installed it properly. The app RUNS!
So once I figure out how to really use it effectively, I *will* be able to produce Apple iBookstore-compatible epubs directly. Yay!
That means you don't *have* to have a really expensive MacBook Pro, Air or desktop Mac to create epubs for direct sale through iBookstore. My iBook ran me $57 w/shipping. The *new* 512MB memory ran $18. The 4-CD OS X 10.4.0 install set was the *big* expense at over $97!
Still cheaper than buying a new MacSystem just to load into iBookstore!
