IDE & ESDI pinouts sought. I have a couple of 400mb ESDI hard drives, and now that IDE controllers are <$20 (in whatever country you come from) I think it's worth my whilelooking into how to wire on to the other. All I know so far is that BOTH require the CMOS to know the number of heads, cylinders, etc, and that both kinds of drives seem to have roughtly the same number of pins (ESDI are card-edge, however) I am convinced that it is a simple matter to hook the two together,@with perhaps just a few logic chips in-between. I'll post the exact method that works when I've done it. in the meantime, I need:- E S D I Pinouts Wanted and I D E Pinouts Wanted Basically, what signals/timings are coming down which wires, etc. Can *Anyone* help me get these, or, help me find out WHERE to get these ? Thanx. Chris Drake sir@external.unsw.edu.au sir@usage.csd.unsw.oz.au
