The pin-assignment for the Sub-D connector can be found in
Prd-70.pdf on page
I also attached the service manual, just in case you guys need it.
I also have the Windows and DOS programming software, just let me
know if you want me to send it.
Actually, I own two of this units back in Germany which I bought
second hand. One was working fine and I used it as a Hotspot for
D-Star. The other unit was never working and unfortunately I never
found the time to fix it.
What do you plan to use your unit for?
