<p>124.157.105.211: </p> <hr /> <div>This project it still under development.<br /> <br /> The basic idea for this project is to add a hard drive via the [[System bus]] on the 100/102/200<br /> <br /> The circuit is based on a 8255 which controls the hard drive data and control signals.<br /> <br /> A 74573 is used to split the ADDRESS and DATA signals and a 138 is used for IO mapping<br /> <br /> The 8255 is split into 3 x 8bit ports, one is used for address, CS, RD, WR and RST. The other two port are used for the 16 data bus. <br /> <br /> [[Image:Mthdv11.jpg]]<br /> <br /> [[Category:Model T Hardware]]</div>
