Jeff,
If it is 1024Z, it is possible that a channel is assigned freely. But, that function is not in a Super8.
Can you understand the electronic circuit?
There has already been lead on a microcomputer in a RD127 to nine channels. It is to connect a resistor and a condenser to a lead of the microcomputer that it is assigned to an eight channel.
Then, draw it with a connector from there outside.
Therefore, RX of eight channels is completed.
I think a condenser may be 1000pF, a resistor may be 470 to 4.7k ohms.
Good luck.
