I think I understand there were possibly 4 combinations of 1.0 light boards (5v, 7v, buffered, non). How interchangeable are those with each other (do I need to know EXACTLY what version I have to be able to use another 1.0 board)? How do I identify exactly which board version I have?

Three versions: 5v unbuffered, 7,5v unbuffered and 7,5v buffered. I think they would work but I would not interchange them to prevent problems caused by that. Best is just to get rid of the 5V. If all is 5V then I would buy the 2.0 upgrade otherwise I would do nothing. I have the 7,5 unbuffered and years without any problems.

I ask because I am looking to solve some issues with my boards without getting the 2.0 kit, right now. I need 2-3 boards and I found some sellers selling all their 1.0 boards but I don't know what boards I have compared to what they are selling and I don't want to change all my boards to another 1.0 set.

Are any interchangeable?

How can I tell one board from another?

Lift the playfield and look on any ledboard for the version. If it says near the version 5v, it's 5V. I believe v1.1 is 7,5v unbufferred and V1.2 is buffered. Someone correct me if I am wrong

Nope. There's a 5v buffered, too.

You can't put too many 7.5v boards in a 5v system. I think the limit is 3?

Ah, I found a post of yours that noted this. So, if I buy ANY "1.x" boards, even if I have the 5v system, as long as I only put 1 or 2 of the 7.5v boards in, then I should be fine?

And buffered or unbuffered doesn't matter as far as interchange?

There are 1.4 7.5v - those will work fine.
Strictly speaking 1.1 version boards have the red / green flipped but there are not many of those out there.

Yeah. In a 5v system a few 7.5v are fine (up toe 3 I think?). Unbuffered 5 isn't desirable as it's the most prone to failure. But really chasing this is a waste of your time since the next time, multiple boards will likely fail again. 2.0 FTW.

You see.... the way I am getting 2.0 boards is buying a RR

So I'm just going to patch up my SE so I don't have to spend 10 hours installing the 2.0 system. The next owner can do that Plus they'll get an almost complete set of spare boards
