Schematics and design files for FujiNet hardware

An IDC-26 to IDC-20 adapter allowing to to use yourApple II Fujinet, Floppy Emu, or Disk II drive on the external floppy port of an Apple III. Based on the work of ThorstenBr, but redesigned to plug directly into the external port and adds the option to route the drive 2 enable signal to pin 17, since Fujinet uses a different pin than the Floppy Emu which expects that signal on pin 5.
