Thanks to the fast and excellent service to replace the faulty one with a working one.
If it doesn't work, I'll find a use for it.
Worked great for a very old product to new PC.
I have read that many of these do not work with the GM Tech 2 but I can confirm this absolutely will work with your GM Tech 2 (It worked well for mine anyway).
Low RS-232 current capacity output makes device unsuitable for some applications.
The cable was unusable as furnished.
I had to use a hack saw to remove it so I could insert the connector.
Bought this so I could connect my old Atari controllers and retrobit controllers to my computer and retrocade.
But either this cable wasn't designed for that or it doesn't work.
