I used Shugart 8" drives wired as address 0 thru 3 w/o problems for single density and double density. the cable is pretty much just a 50 pin idc on the tarbell controller end, and whatever fits your floppy drive on the other. I never had 5 1/4" drives wired up, though you supposedly could do so. Beware the Tarbell densities over the regular 8" single sided 256k format was not readable by much else.
