This project it still under development.

The basic idea for this project is to add a harddrive via the System bus on the 100/102/200

The circut is based on a 8255 which controls the harddrive data and control signals.

A 74573 is used to split the ADDRESS and DATA singnals and a 138 is used for IO mapping
