If the new computers support PCI-Express (PCI-e) boards, you could
investigate the LSI Logic "LSI20320IE" board that fits into a PCI-e x1 slot
and provides single-channel U320 SCSI (via both internal and external
connections for 68-pin "SCSI Wide" cables).   The HP part number for this
card is "HP 439946-001" and the Dell OEM part number appears to be "NU947
MM052".  Adaptec and other(?) manufacturers may offer similar products.

I have the HP-version of the LSI20320IE board installed in an HP z800
workstation on which I am running SL5.X, and I have had no compatibility
problems with the native Linux SCSI drivers.

Hope this helps,

P.S.  Your e-mail did not say whether you needed support for hardware RAID
capability with your legacy U320 SCSI hardware, but I believe there are
other U320 SCSI boards available with PCI-e interface that do provide
support for hardware RAID, although according to TUV this really isn't a
necessity given that software RAID can be used instead ...
