Hi 
Wondering if any one can help and advise me on my TX81z.
I am using Tx81z a brillent unit and would like to save all my sounds.
I have not worked on them before so Iam wondering if I can save and 
load my sounds direct to my computer and also I note that it is an 
8pin din plug at the back my unit.
To make up this cable can anybody advise me on the wiring connection 
from 8pin to the 2 leads
Any help would be grateful
Regards
