Can't help too much with cables. You might try Black Box, Inmac, or
one of the other mail order houses. Our local Sony distributor made
us a cable to attach the Sony SMO-501 optical disk we bought from 
them (centronics-style w/wire clips) to our Sparcstations (50-pin
D connector). Try your tape drive dealer.

As for making the connection to your DN3500 ... run the "jumper"
program. It's located in either /systest or /systest/ssr_util
(I haven't had my coffee yet ... it's too early to go mucking
through the file system). Look at the jumper configuration for
the WD7000 controller with the SCSI bus enabled and check it
against the jumpers on your board. Remember to terminate both
ends of the SCSI bus. There is a resistor network in a socket
near the SCSI connector on the WD7000 board which terminates
that end of the bus. If you have both internal and external
SCSI devices (the disk drive is NOT a SCSI disk!) then the
resistor network should be removed, and the SCSI devices at
the end of both the internal and external chains should be
terminated.
