Feedback from one who knows:
The early signal cable on the Shugart SA900 was a twisted pair cable
terminated on a connector with 0.156-inch centers to make the use of ribbon
cable impossible. This was done to avoid cross talk noise problems using
ribbon cable that the engineers had experienced at Memorex. Shugart
switched to 0.100-inch centers for ribbon cable for customer (cost) reasons
and had zero problems. There was only one cable for both control and data on
the Shugart 8" FDDs.
