Geoff and Louis,
I have been working with a company to develop a replacement display for
the Corsair I and Corsair II. The company is sending me a prototype to try
out this week. If it works, and I believe it will, we will have a fix for
the defective U10 problem. Mechanically the new display will not be the
same. A person will have to remove the display board (but keep the display
logic board) and mount the new display doing some "sheet metal" work to
mount it. Five signals which go to the display logic board are "tapped" off
and soldered to the new display. The new display will be available in
different colors - users choice. Cost will be reasonable. I am excited
because I know a lot of Corsairs have been abandoned because of the display.
I will keep the group informed and take a few pictures to show everyone.

We've discussed this before in relation to other radios. It depends
upon how many unrepairable radios there are because of this part. If
most of them are perfectly good except for this part, then yes it
would be worth it. If most of them are unrepairable for other reasons
and this part is still good in them, it's not worth it.
Anyone have any hard figures? Guestimates? SWAGS?
Geoff.
