The Victor 9000 had a variable spindle speed, I cant remember if the
drive spun faster on the inside or outside tracks. Also, the index hole
detector was not used. Many of the drives did not have a index
detector, on the drives that did have an index hole sensor, it worked
just as well without it plugged in. I got in a argument about the
ability to use hard sectored floppies in the Victor 9000 with a Victor
sales rep once. Even after I showed him that the index detector was not
connected, he still didn't believe me.
