I'm just going to rewrite this cuz it didn't make sense the way I wanted it to:
I can't imagine there aren't U3W controllers on ebay, U3W is Ultra160 SCSI. And even if there aren't, any LVD type controller (from 80 mb/s Ultra2Wide to 320 mb/s Ultra4Wide) will work. The one big issue is if the drive is a SCA 80 pin (designed for SCSI backplanes, has a single 80 pin connector and no molex) or standard LVD 68 pin centronix (has a molex connector and the "standard" 68 pin scsi port most bare controllers have). If its an SCA unit you'll need an adaptor to make it work. Putting the PN in a search seems to indicate it is in fact an SCA 80 pin unit, so you'll need an adaptor to make it work with most standard controllers. If you can find a Dell LSI based controller on ebay they tend to work, my LSI 21320R is actually a Dell branded card flashed to original LSI firmware. I think I paid 40 bucks for mine.
