Re: NT20 to TMP Octal socket cable pinout
Pin 8 on the CPC seems unaccounted for, is there anything there? This pic from a cable shows a pin at 8

Re: NT20 to TMP Octal socket cable pinout
I got a cable made up according to John's pinouts and its working. One note, the actually PIN number for an octal base are the opposite from what John stated if you do have a octal base with pin markings. It goes counterclockwise from left of the key looking at the face with holes where the pins go.
So the pinout would be:
Octal CPC
8 13
7 14
6 11
5. 2
4 3
3 6
2 7
1 4
So the pinout would be:
Octal CPC
8 13
7 14

Re: NT20 to TMP Octal socket cable pinout
Thanks John and Jerry! I have a turbovac 151 coming with a broken cable (and for the wrong controller) and was searching for exactly this pinout for the NT20.
