Yes there are. This is but one example of a (Mac) PCI slot card which
features SCSI (to 40MBytes/s) and 1394 (up to 400MBits/s, or 50
MBytes/s) so you can connect either a Firewire (1394) scanner - like
the new Nikon LS4000, or your older SCSI scanner. Or both!

This particular card is rather interesting because it also supports
Ultra wide SCSI drives, Edit DV, and RAID.
There are others, including a 1394 to SCSI connector. As far as I
know there are no connectors which convert SCSI (in) to 1394 (out).
But there is the reverse. You would think that Nikon might want to
build such as device, however.
USB is currently too slow, in its current ramification. USB2 will be
faster. Firewire is currently 400 MBits/S, will go to 800 MBits/S
2001, and >1GHz the year after. So you can see why video/media
hardware companies are moving this way.
But a card like that above places a lot of versatility on your computer.
