"LCU Guide to Toppers" ........
"Red, Blue, Green... Red, Blue, Green" issue is a lack of proper firmware. The R,B,G sequence is an error code of an I/O device being "offine" (Not communicating). WAVE Toppers and PRO LED speaker boards require Level A05 (or newer). "A05"'s are NLA and supersede to the "A08" board.
Here's the PROPER information you'll need when calling around for the LCU board... The used ones Larry has/had are Bally PCA212710. They will accommodate firmware upto "A06". Jumping up to an "A08" Flash requires additional data buses for the "Crown" Toppers, etc (There are 3 separate boards in that Super Topper that require DATA inputs). Thus a DIFFERENT board number. Bally PCA245970 is the CORRECT part number you want to give for a board with an AXDUOABZL020A08 Firmware Flash. The boards are BLACK, not green.
Hope this helps....
..... And yes, The Super "Crown" Topper is a boat anchor without the "A08" to drive it.
Barry, Yes all that you said is right I think. Maybe Im repeating the same info. If so, sorry. But I have tried each topper trying to figured out what was best. And basically what I found was that each topper that is chrome w/LED side and has a black plastic cone support base could use the A05(15", 18.5"). I did find that the 22" chrome plastic w/LED side and has a plastic cone was different. (I didnt take pictues, sorry) 1 of them I tested had a cone base and it worked with AO5, The 22" chrome plastic with the plastic cone with a flat base did not work with AO5 but did work with AO8.
Now that is not saying that the controller board on these monitors were the same. Some may be the same and work fine. Others maybe different. I really dont know. I only know what I have tried.
As for the v27/27 topper, it took a AO8, the WAVE Topper took a A08. I havent got my Super topper in yet, so I cant say... but get me a week an I'll get you an answer.
As for the the A08 Card, they are not hard to find............
