The A314, allows you to use a Raspberry Pi as a coprocessor on an Amiga 500. The expansion card, designed by Niklas Ekström and Mr. Rönndahl fits into the ventral hatch of the machine. The Raspberry Pi and Amiga can communicate with each other through a communication protocol created specifically by both authors. There is for example the file system “a314fs” which allows the Amiga 500 to see a directory of the Raspberry Pi through the volume AmigaDOS PI0 :. There is also the “pi” command that allows you to run an executable on the Raspberry Pi.
