Digital Interface Schematic page
The first schematic below is an overall schematic of the completed project.
It has been broken up into 4 separate sections below and enlarged to show detail of each section. The separate sections are presented in order down the page and numbered 1 thru 4 and are about 1/4 each of the overall drawing.. If some of the connections on the 4 schematics below seem to connect to nothing, just remember to refer to the overall schematic. You may save each to your computer by right clicking on each and save to the file or folder of your choice.
