I have an SE/30, micron Xceed Color 30 and the original CRT board. But where did the internal wire-harness go? I have NO idea! So, if anybody knows of someone who makes them or have a spare (fat chance), I'm in the market!
PS. The reason the harness is gone, is due to the fact the Xceed and the CRT option has been bought separately - some 5 years apart, actually. Bought the CRT board 5 years ago, and the Xceed only a fortnight ago.
