Cool.  Too bad I just bought a 2940  :-(
Anyway, thanks for the info!

Now, where can I get these cheap but excellent NCR controllers
everyone raves about?  I'm going to be getting a ZIP or EZ 
external SCSI (since the parallel ports on these cheap clones
only give about 50K/sec) to do backups at many other computers.
Cost is of course an issue.

TIA!
