Blue still available!
Yes when the key is turned, it lights up without messing with the modulation wires.So when you plug the laser into the wall and turn the key, does it light up without any further action? Or do you need to apply voltage to the modulation wires to get it to light up? This isn't too hard to determine.. it's as simple as yes or no.
I'm guessing that since it's lit up in your pictures it's TTL, but I can't see if you've got anything connected to the modulation input.. If it powers up and produces light with nothing connected to the modulation input, it's TTL for sure.
