The key matrix of the Voyager models is wired like this (hardware keycodes shown in key positions):

Code:

         KC0   KC1   KC2   KC3   KC4   KC4   KC3   KC2   KC1   KC0

           |     |     |     |     |     |     |     |     |     |

    KR3--0x13--0x33--0x73--0xc3--0x83  0x82--0xc2--0x72--0x32--0x12--KR2

           |     |     |     |     |     |     |     |     |     |

    KR0--0x10--0x30--0x70--0xc0--0x80  0x87--0xc7--0x77--0x37--0x17--KR7

           |     |     |     |     |     |     |     |     |     |

    KR1--0x11--0x31--0x71--0xc1--0x81  0x84--0xc4--0x74--0x34--0x14--KR4

           |     |     |     |     |           |     |     |     |

    KR8--0x18--0x38--0x78--0xc8--0x88        0xc5--0x75--0x35--0x15--KR5

I don't have the pin assignments for the QFP version of the Nut CPU, but the equivalent for the original DIP package is:

KC0 - 17
KC1 - 16
KC2 - 15
KC3 - 14
KC4 - 13
KR0 - 27
KR1 - 26
KR2 - 20
KR3 - 25
KR4 - 18
KR5 - 21
KR6 - 24
KR7 - 19
POR/KR8 - 11
