I'm guessing most of our readers are not old enough to remember the IBM XT or even adding your own I/O cards, I bet a large percentage of them have never even seen a IBM brand PC, oh how time moves on, but some people want to go back and thats what this guy did, he made a IDE card for his XT.  There's some links on where to buy a PCB if you really want to make one, but good luck finding a PC with ISA and no in built IDE controller thats still barely usefull :p

"Once I started messing with my IBM PC XT, I realized that there were things I had taken for granted all along since my first PC compatible system was a 386.  I didn’t realize that IDE uses a 16-bit bus and it would take some trickery to use an IDE device in an older 8-bit system like the XT.  I searched around and found that there were in fact 8-bit ISA controllers but they were expensive and rare.  Finding one these days would be a stroke of luck or a dent in the pocket book.  I was about to design my own when I came across the XT-IDE project.
