I believe the .75 inch stuff is 5xxx; can you tell me what an IPI-2 
interface is used for?  

Also, I have a CDC 94601-12GD, which I am guessing is a differential
drive but I don't know what the G stands for and I don't see any reference
to it above.  Since Seagate bought CDC, I'm trying to avoid calling them
and waiting on the phone for an hour to find out what it is.  Any help
much appreciated!
