CF Card interface

The first iteration of the project used a 40GB IDE hard drive from an old laptop. I used the IDE connector convertor to change the 44-pin drive IDE to a standard 40-pin IDE ribbon/connector.

The IDE interface uses a 8255 PPI device that many use in similar projects.

I got this on Amazon.com for $12.

The IDE CF interface and CF card are mounted on the right, connected through a standard IDE ribbon to the 8255 PPI IDE interface ISA expansion card on the left.
