I'm looking into writing a floppy driver for the sparc. The newer Sun
machines use a 82077 clone controller for which I have some docs.
The older models use a 82072 device for which I have none, but must be
operating similarly.

Specificly, has anyone information on:

	- how to turn a drive's motor on
	- how to configure the device FIFO buffer (for PIO)
	- how to set implied seek (if this is at all useful; the
	  82077 seems to have it)

Thanks,
