I have yet to see an old SCSI scanner that won't work on new PCI SCSI cards ... the one thing that's very frequently
overlooked is SCSI bus termination. Those old and slow ISA SCSI cards don't care, the new ones certainly do - and
since most of these old scanners neither have means of terminating the bus nor mention it in the manual, most people
fail here.
These scanners usually have two SCSI connectors. Use the better one for the host connection (prefer 50-pin high density
plug over 50-pin legacy SCSI plug over 25-pin el-cheapo plug), and put an active type termination plug onto the other one.
I've had success with old Umax, HP, Epson and Mustek scanners once I figured this out. Using Tekram 315U or (preferrably)
LSI 20860 for that.

(btw: Newer chipsets simply don't provide an ISA bus anymore. AMR/CNR stuff actually does exist - it's big in the OEM build
market, and ECS/PC-Chips offer cards for retail and even ship them for free with some of their board models. Having used
plenty of these, I must say that these $9 or $0 AMR modems are far from useless ...)
