Ross) Distribution: world Organization: Structured Home for Disturbed Programmers Lines: 21 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. -- There's sparks a comin' outa' my head!!! ...!harvard!umb!ileaf!ebr Evan B. Ross, Interleaf, Cambridge, Ma ...!sun!sunne!ileaf!ebr (617)577-9813 x5570
