See Figure 19.
The drive device connector is a nonshielded 68 conductor connector consisting of two rows of 34 female pins
with adjacent pins 0.050 inches (1.27 mm) apart. The connector is keyed by means of its shape (see Figure
21).

9.6.4.3
Mating connectors for “WC” and “LC” models
The nonshielded connector shall be an 80 conductor connector consisting of two rows of 40 contacts with adja-
cent contacts 0.050 inches (1.27 mm) apart. I/O connection using a cable is not recommended. The length and
size of the host equipment DC power carrying conductors from the DC power source to the host equipment 80
pin disk drive interface connector(s) should be strictly designed according to proper power transmission design
concepts. No possibility for the equipment user to attach an 80 pin cable/connector should be allowed, since
the length of the DC power carrying conductors could not be controlled and therefore could become too long
for safe power transmission to the drive. Daisy-chain 80 conductor cables should especially not be allowed,
since the power-carrying conductors on the 80 conductor interface were not intended to support a series of
drives.
