Yes, it's the standard SCSI-2 connector. (iirc, the DECstations
formally predate scsi-2, but the connector and the protocol is pretty
much standard scsi-2.)  The same 50-pin connector was used on
most workstations throughout the late 80s-mid 90s-- sparcs
and NeXTs use them.

Fry's or NCA or a similar outlet should have the cables.
It depends whats on the external drive.  You want a cable with
scsi-2 on one end and whatever matches your drive on the other.

Er, you mean the old MacPlus-style db-25 connectors, or
Centronics style, or something else?
