It can't be done with just passive components.. ie you will need either a
differential<->single-ended converter or a differential SCSI card. If
you're using a machine that takes PCI cards, then a card will be cheaper,
but if you're using it with a VAX or PDP-11, etc, I'm doubtful you'll find
a differential-scsi interface, and will need to buy an interface box.
If you need/want a PCI wide/differential SCSI card, I have several Adaptec
AHA-3944AUWD's (with PC BIOS ROMs) that I would be willing to sell at a
'reasonable' price (probably $40 + shipping).
As far as 'converter boxes' go, I don't know what one would cost, because
I've never had to buy one.
