Has anyone made an apple II layout that shows the disk drive LED status?

I was fiddling around and can see the status in the sl6:diskiing;wozfdc/0/external_io_select (0 for drive 1, 1 for drive 2) and the motor in sl6:diskiing;wozfdc/0/active (0 for off, 1 for on, 2 for getting ready to stop)

It should be theoretically possible to do a track LED display too like those indus GT drives.
