<OT> SCSI drives

[Tony Alfrey]

Can someone briefly explain the differences in SCSI drive pin formats?
Specifically, I have Seagate 68 pin internal SCSI drives.  I believe 
that they are the so-called "Ultra 2 LVD" format.  But there appear to 
be other SCSI formats that have the exact same connector, for example, 
something called "SCSI-3".  Can someone recommend a simple summary of 
these various formats?
Thanks!
