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! Mith
