Help: can you make that "drive" spin?

[Maurizio Brancaleoni <sir@rcvr.vr.it>]

I ran into a problem. A very old Apple ][ game stopped showing an
animation and asking me to "Insert disk XXX into drive 1". No option of
a successive <Press return> or the like. Simply changing the disk image
got no result.
Is there a way to let STM emulator know that the disk "is in" the drive
and so "spin" the "motor"? In other similar cases I successfully jumped
out of the loop, but now the animation makes isolating the waiting loop
nearly impossible. Can somebody help me?
