8051 Development System Circuit Board Schematic Drawing This is the complete schematic for the development board. Address and Data bus wires are drawn separately (not in a bus), so that it's easy to color over them on a printout, if you choose to manually connect the wires. It really is easier to buy a bare circuit board, though. Posted Image Also, the original (ugly) schematic that Forrest used to create the circuit board is available for download, as a postscript file, or a bitmap image.
