As this device has no screen, a low level diagnostic routine is inferred from their discovery. Looking closely at the last string or two, I was worried that it might be corrupted as there are some missing letters in the string - (ADAT Sync port di onnected and Dectected rather than Detected).

There was actually some DOS software that I had a crack at too which apparently loaded H8 firmware but I never got it to open the file.

I find Ghidra and compile Dev version for some reason I can't recall. I think so I could load third party CPUs.

'''H8300H is not supported in Ghidra'''. I find a plugin, https://github.com/shizmob/ghidra-h8-300 and try to compile that and load in Ghidra. It won't compile though - Later I also tried https://github.com/carllom/sleigh-h8 which I also don't get running in Ghidra -
