Great!  Thanks!

Which LVD should I get to put on my 50-pin 2940U controller (with
adapter):  ST39173LW or ST39173LC ?

LW = 68-pin Wide SCSI connector, low-voltage Differential 
LC = 80-pin Single connector SCSI connector, low-voltage Differential 

So LW looks to fit a regular wide cable.
What's this 80-pin connector on LC?  Is this the new wave?

Thanks a bunch!
