I can see 3 cables. One to motor control, the other 2 to 2 backplanes. I
guess backplane 1 is read, 2 is write, as 2 has less boards. All are
fully populated. What do Pertec Unformatted Interface cables look like?
These look like IDE cables.
However, I
also found that the HPIB interface consisted of a removable
cage with three cards and its own power supply. Once this subassembly was
removed, the drive itself appeared to be a standard Pertec interface. I
have yet to actually try it, but a pair of 50-pin card-edge connections
sure look like Pertec to me.
If it's two 50-pin connectors, it's a Pertec Formatted interface.
Lots of older drives have within their bowels yet another set
of cables: the Pertec Unformatted interface. This is three cables,
one carrying control signals, another carrying read data, another
carrying write data.
