Exabytes are pretty classic SCSi tape drives.  They come in 
single-ended and differential configurations, you need to 
check which you have.

The downside is they have a short working life.  Back in the 
day, there were outfits that would
rebuild them at an affordable price, I think they 
cannibalized video drives for parts.
I don't know what failed on them, but it seemed that 
whatever it was would fail even if powered-off and sitting 
on the shelf.

You should have no trouble running them on anything that 
handles SCSI tape drives.
