hard disk and PBP

[sayzer]

Ok, here I have a link for controlling IDE harddisk drive with a PIC.

I am just posting the link and the schematic here to provide some ideas for those who are interested.

No comment whatsoever.

I suppose there's a million different ways to do it, but I did the upper 8 bits 2 different ways, one with stacked 74LS574's with the OE* & Latch pins seperated and once with a 74ABCT2952 (basically a bi-directional 74LS574 with direction-dependant Latch and OE* pins).

But I never thought of using a 4014 for the upper byte. Interesting indeed...
