There are 3 variations of light boards for WOZ:
1. Original 5V boards. People had lots of problems with these boards failing. When one board goes out all subsequent boards also stop working.
2. Updated 7.5V boards. These seem the fix the frequent failing issue BUT still have the same fundamental design: when one board goes out all subsequent boards also stop working. (Not sure when these started but they are in my WOZ with build date 12/29/15)
3. Updated "2.0" boards. Redesigned boards such that when one board goes out, subsequent boards continue to work. (According to KingPinGames this was incorporated to games built after 12/15/16).
Quoted from whthrs166:I have a WOZRR 75th. 11-5-15 build date. It has the 2.0 boards.
@whthrs166, I believe this is incorrect. Based on that build date you would have #2 above not #3. It is the second version of the board but not the "2.0" board. I believe the "2.0" label applies to just #3 above. KingPinGames are someone more in the know can correct me if I am wrong.
