16C schematic
Can anyone point me to schematics for the 16C (or 10C/11C/12C/15C)? I only need the keyboard connections: cpu row & column connections for each of the keys.

Thanks, Monte

RE: 16C schematic
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

Eric:

I have no need at all for this info, but I still feel compelled to thank you for the elegant and clear way of expressing this info, and for the insight and patience to create this to share with all. Very cool, and a hearty well-done!

Hi Mike,

I guess that the value KC3/KR3 must be the 0xC3 because all other values in the KC3 column have a "C" as first digit.

By the way, does the "(Stgt)" part of your login name mean "Stuttgart"? Then you would be in the same area as I am.

Best regards

Karl

You're right. I've updated the post.
