I just read the wikipedia page for the B&W Power Mac G3. At the bottom, it says that there were 2 revisions of it, I have the 350MHz one and was wondering how to tell the difference between the revisions. I think I have the A revision because I have the hard drive bay with the 3 drives side by side. On the wiki page, it says that the A revision had problems with 2 drives at once. Is this why I can only boot into OS X on a Master drive and can't boot OS9 on a Slave drive?

The HD controller on the first run logicboard could only take 1 hard drive and had problems with data corruption on larger hard drives.
You have a newer version since you can use more than 1 drive at a time.

According to xlr8yourmac.com, I have the 1st revision logic board. I'm guess thats why I can't boot into OS9 on the 20GB drive. My hard drives are current in a Concatenation RAID config with OSX on them. I don't get why this is reliable and having OS9/OSX on two drives isn't.

No, even the Rev A was capable of supporting slave drives. It just required a replacement drive data cable with three connectors, and of course has the problem of being incompatible with essentially every hard drive released after the machine was sold.
