I was able to source some CS5208-1 from Kynix. Had good results ordering obsolete/obscure parts from them before:
?
Also finished designing some adapter boards to bring the A3 out of the chassis and allow for "hot" testing.?
They connect together using Samtec SFSD .050" wiring harnesses, which come in all sorts of lengths. Hopefully 24" of wire doesn't mess up signal integrity too much.?

I just ordered parts and boards. If its successful I'll share gerbers and BOM so others can use.?

In the mean time, does your firmware disassembly have any useful hints as to what that error means? Looks like its pointing out a particular .cpp file in the FW related to the A3.?
Also, if anyone has info on LEDs that would also be great. Wish I had a working unit to look at and compare which LEDs are lit/not lit. Of course service manual doesn't say anything.?
