Success 
!
I was able to get Drive Setup on the Centris, it found, and then formatted the drive to HFS and I think I'm good to go. Thanks for that hint, I don't think I would have found that otherwise.
As for how I got it to the Mac, I chanced upon the TransMac software, been using it ever since, haven't had much choice since I only own PCs [
] ]'>
Also thanks for the lesson on the jumpers, even though I was aware each drive had to have a unique ID, etc, I haven't had much experience in dealing with drives to know that some have things set automatically.
I'm going to proceed to get OS 7.5.5 on the new drive, then wipe and remove the old drive. I hope to get a cd drive for this soon, so hopefully I can get it right the first time
Again thanks, I'll probably have a few more questions once I actually get this thing setup
