Hmmm..... I'd keep looking.
Do a Google search for SCSI cables.
I'm guessing but I would think you should be
able to find what you need for $10 to $15.00 U.S.
Why do you need an 8 device cable??
Usually 4 or 5 device connectors will handle
most setups.
If you had needed a 50 pin, I could have made it
for you.
Check the surplus cable sites on the net.
As an example, CompUSA wanted $18.00 for
a networking cable. I found a site on the net
and got the same cable for $1.80 with a minimum
order of $12.00 so I padded the order with a few
more cables and with shipping still came out ahead.
