Some weirdness happens on the prototype boards, must be a software issue. It's always software. Has to be. Hmm, let's see how that looks on the old breadboard.

And we got a Golden in the '80s, when my son was young, and had it for 13 years. Ours were far darker than Spef's, though. We'd get another but it's difficult to travel when you have dogs. Cats are much easier to take care of. Food and water and they can be left alone for several days.
