Bally, 1992Price Drop $10 shipped.
Used DW opto board set for the time expander. Was giving me trouble with the two parts shown so I bought a new one...of course then I realized that I didn't have to spend $40-50 plus shipping and probably only needed to replace a few parts for a few bucks. Couldda saved some money, but my loss is your gain.
IMO, you didn't waste your money. I also have a Who pin and those boards flake out quite a bit, especially after several years of getting smacked by a ball. I finally bought the newer, thicker boards. Since I've replaced them I haven't had a single problem.
I think the problem may be that people are reluctant to putting any money into a board that's damaged.
Truth is, this board is crazy simple....not much to F-Up. Perception is that all boards are incredibly hard to work with.
If I could suggest, why don't you fix the board and sell a **working** repaired board set for $25+
Testing is simple. Continuity tests for your own sanity... then.
The receivers will have a resistance change when exposed to a mag light (put your DMM on the pads).
The senders need a power source. Jumper from the connector to the pad and view each LED with a digital camera.
Just a thought. Or perhaps this post may inspire someone to take a chance on a great priced board set.

Price drop. Too many projects. I'm almost 100% sure it's just those two pieces. Only asking five bucks plus shipping. Otherwise it's probably going in the trash.
