The correct commands to get the 1571 into double sided mode are:

		u0>m1         (enters double sided mode)
		u0>m0         (enters single sided mode)

I have used the 1571 double sided mode with the C64 mode (have C128) with
no problems. The only trouble is that the 71 defaults to single sided mode
when the machine is reset (in 64 mode) or first powered up (in 64 mode).
This makes it necessary to send "u0>m1" to the drive each time you reset,
but this isn't a big chore if you have the built in wedge of
SuperSnapShot v5 ... :-)
