This is about using a 8255 and a 63B03. To my knowledge, nothing for the PIC has been published for IDE. Should be possible with IO expansion (shift or parallel registers) or using one of the big (50 io pin) Scenix chips. Please post your code if you write it. All I know is at http://techref.massmind.org/drives Please let me know if I missed something. --- James Newton mailto:jamesnewton@geocities.com 1-619-652-0593 http://techref.massmind.org NEW!
