I'm working on a little project to bring back a 1A2 gizmo that seems to be made of unobtanium these days. I have some custom made PCB's on their way to me, but they haven't come off the boat from China yet. Here's one I threw together on a piece of perf board. It is the exact same layout as the custom PCB I designed and almost a perfect copy of the original. Can anyone guess what it is and what it does?

I hastily pinned it to my backboard and hitched it up, and it works just as well as the original. I will be making 50 of these to start, and if anyone is interested in them, let me know. (obviously once everyone knows what it is)
