Well, the 800/801 OEM manual speaks to a 'sector separator' which is
bypassed when the 800 trace is intact. The 850/851 manual, on the other
hand, speaks to a 'data separator' which is invoked when the 851 jumper
is installed. I guess both provide comparable capability, depending on
whether you want to 'see' the sector pulse or not.
