Click here to see a cabling diagram for dual-drive configuration. (Two hard drives will require an upgraded PSU, one that is able to cope with the power requirements.)

Click here to see what the terminating resistor (terminator) and shunt block on the IBM supplied ST-412 looks like.

Click here to see the difference between a floppy twisted cable and hard drive twisted cable.

Click here to see what I call a double-twisted cable, a cable with twists at two locations. Rare, but it needs to be compensated for.
