Can an additional PCI SCSI card be installed in the 670, in addition

I read somewhere in the docs that only the integrated SCSI can
function at one time. The box has two U320 SCSI HDs.

I don't know what would be so different about the 670 that it would not accept a SCSI card. The best advice I can give is to get yourself an Adaptec 2940 or 2940U and try it. You probably do not want a 2940W or other adapter with a wide 68-pin external connector, which would only complicate matters. 2940 and 2940U adapters are very inexpensive now, so you would not be throwing away big bucks.

I have an Adaptec high-density (connector) SCSI card in the existing 610 Wkstn, which the 670 is replacing, that can come out and get popped into a PCI slot. It's a BIOS-less adapter card whose model number I cannot recall, but it looks like an AIC-7850 in device manager.

With the newer LVD SCSI hard disks, an older single-ended SCSI card is necessary for a SCSI scanner, SCSI multi-function flash card reader, and older SCSI tape drives. AFAIK, one cannot mix LVD and SE on the same (newer) SCSI channel. LVD and SE are two different and incompatible electronic signals... Ben Myers

Without a BIOS, the card is something like an Adaptec 2910, 2920, 2930 or similar. The low 2900's from Adaptec were almost all basic SCSI cards without BIOS, hence unable to support booting from a hard disk or CD-ROM.

You must already have the external cable with high-density connector on one end and whatever (50-pin?) connects to the scanner on the other end. If you are running Vista on the 670, be prepared for the possibility that the scanner won't work, and do not look to HP for software support. Well, not completely. I have had some success using scanner software for a newer HP SCSI (must be SCSI!) scanner with an older ScanJet, but, then, my success is limited to Windows 2000 and XP. Vista, as we all keep hearing, is a horse of another color. Maybe it's not even a horse at all, but a donkey.

Because the SCSI scanner manufacturers have all be capricious (I'm being nice here) in supporting their equipment with newer versions of Windows, you might also look at 3rd party SCSI scanner software, for a price... Ben Myers
