So I had to open it!
Also opened a 'Rev 2' unit to compare!

And indeed, the pinout is different, while the 'Rev 2' have mention to 'USB' on pins, the 'Rogue' one does not.
Later I will try to open a '30th anniversary' to check if it´s the same pinout as the 'Rogue' unit.

PS: neither of them had the springs that other 12C units I opened had...
