The cable is a piece of cake to build. Straight through from the
edge connector under the back of the 4D to the header connector
labeled "Computer In". The other connectors on the back of the
drive are for connecting up to three additional drives to the
controller built into the one you have. (The short cables from the
controller to the empty data out cutouts came with the secondary
drives. They too are easy to fabricate.)
The connector under the 4D _should_ be labeled expansion bus or
something like that -- I never did much with the 4D, they came out
about the time I left the company.

firearms with me. I said "Well, what do you need?" -- Steven Wright
