I saw it, but didn't recognize it. He was soldering and I was trying to figure out what it might be. It clearly was being used as a prop, some random board (or maybe it was deliberate) so he could be shown soldering.Did you see that Howard was soldering on an Apple ][+ main board on Thursday's Big Bang Theory. ;-) It's about ten minutes into the episode.
Since we saw the edge connectors (which was what made it clear to me that it had to be some old computer board), Howard seemed to be soldering on the wrong side. Unless he was tacking on a wire, you don't solder to the top of a board.
