I can confirm that the sys 9/11 led ocd board works fine with a sys 6 in a Flash. I did have to make custom cables, which took a bit of time to map the pins between the sys 11 and sys 6 headers, but otherwise everything works great. Since driver boards from sys 3-7 are pretty much identical, I can't see why this wouldn't work for any games in that range. I did try the software to switch to manual control, make brightness changes and enable/disable passthru, all of which worked as expected.

The improvement is perhaps not as dramatic as in newer games with light shows and more active blinking, when without the led ocd the rapid turn on and off of the led's is distracting. However I had already brightness matched and used non-ghosting led's as well so there was not much tuning needed, but if you just tossed a set of cheap led's in and then adjust the settings it would probably make a bigger difference. One big positive was the annoying strobing due to the lamp matrix scanning was totally gone.

Now I just have to wait for more boards to be available since I took the led ocd board out of my Whirlwind and really want one back in that machine as well.
