        I've been looking at the signetics Intelligent Multiple Disk Controller
        (imdc - 68454) and thinking about building a hard-disk interface
        for my amiga.  The real question, however, is whether or not the
        imdc's dma will work in the amiga environment.

	The expansion spec tends to be a bit vague on some of the signal
	timings and I was wondering if anyone had any comments/advice about
	hooking up dma masters.

        Can the amiga cope with a dma master is running asynchronously to 
	the 68000 clock?
 
        All comments and help are gladly accepted.
