Thanks Pete!
I think I have one Cruise M... if yes, I'll give it a go. If I can handle that I'll get two more for the others. All the speakers sound the same in the 5 quasi modern conventional size GG1s I have. Train Electronics Kindergarten starts now!
Whoops!!! John got in between posts! Does the ERR RS Commander for GG1/EP5 negate the Cruise M or is it a different board? This is exactly where my knowledge base is lacking... Notebook started.
