Справочная информация и описание кабеля
ESDI
The ESDI interface requires two cables, one for control and
one for data. The control cable is shared between the two drives.
But each drive has each own data cable. By twisting some wires on
the control cable it won’t be necessary to set the ID for each
drive, since the twist will do the job. Wires 25 to 29 should be
twisted between drive 1 & drive 2.
