Are those tapes 3080XL...? I've a conner which uses 3080XL (something like
that - XLF or XL??), stores 2GB, SCSI-2. I've been using it on my
Alphastation for daily backups for the past year or so. I've never had a
problem with that drive at all. It worked on the internal NCR SCSI
controller, as well as on the 2940 which I now use.
I think the model was something like CTMSxxxx. I'm not in front of the
machine now, but I can grab the info tonight if you're interrested.
