Regarding floppy disk drive A/C motor controllers, the questions to
be answered are:
	o  Must one build in a software delay to allow
	   motors to ramp up to speed?  Obviously, this
	   is necessary and it may slow things down
	   too much to be tolerable for normal operation.

     	o  How does the software know whether the motors
	   are spinning or not?  If the software doesn't 
	   know, the delay for motor ramp up has to be
	   built into ALL accesses.  

Remember the TANSTAAFL Principle (There Ain't No Such Thing As A Free Lunch).
