Sorry, didn't answer this part of your post: From my read of the
technical manual, it is hard sectored. There's a dedicated index track on
the bottom of the lowest platter and a dedicated, fixed head to read it.
It's more of a synchronous counter than a sector pulse. There are DIP
switches on the board to set up a divider circuit that turns this pulse
train into discrete, properly-spaced index pulses. Thus, the sector size
is configurable.
