So the winner of July’s name that ware is Joe Martin, congrats! Please contact me for your prize. I think Joe’s explanation was the most informative, pointing out how the channels were routed in lexan and bonded together. I still don’t know definitively what this ware is, but the little poking around I did agree with the idea that this is used mostly in dangerous settings, such as nuclear reactors or in the presence of highly unstable chemicals like silane. And yes, I’m “that guy” who bought it from Halted specialties :-D I had read about pneumatic logic before, but I had never seen one in real life, so I was really excited to see it on the shelf. I just had to get it to add to my collection of weird and wonderful electronic artifacts. I’m surprised that people recognized it from seeing it there on the shelf!
Hey, so change the name to “explain that ware”, since he talked about (obvious) things, like the channels were routed in lexan (which anyone can see) but no one but me told the name, manufacturer and other data about that. I’ll put a complete datasheet next time just to be sure I’ll win :oP
