The net4801 contains a SC1100 processor and a PC87366 I/O controller. Both chips have GPIO pins. I think the GPIO pins of the PC87366 are used. To see how it is wired I would like to have the schematic diagram of the 4801 printed circuit board, but was unable to find it on the Soekris site.
Is this diagram available?
