80 pin SCSI hard drives.

[je killen]

I've obtained two SCSI hard drives made by Maxtor that have 80 pin 
connectors and no power connector port.
This isn't necessarily relevant to FreeBSD accept that i'm planning on 
using them in a FreeBSD installation.
I'm only aware of 50 pin SCSI and 68 pin SCSI. I've tried to contact 
Maxtor to get advice on a PCI adapter
and cables to use with these units but haven't gotten a reply.
Can any one give me some info on how to set these drives up hardware 
wise?
  Or if they can be used, maybe I made a mistake getting them, but they 
are 18GB 15 k drives and were $75 apiece
from Tiger Direct. two of them will give me 36 GB to use for a web 
server  /usr and /var partitions. And  i"ll use SATA
drives for RAID back up.

Thank you in advance.
