    Mike, I'd suggest joining the Groups.io ft990 user group. In the files area is a file "GeneralTroubleshootingB.rtf" that provides a lot of helpful information for troubleshooting an FT-990.

    If you describe the problem you are having on the ft990 group, it may turn out the problem is not on a plug in board but on a mounted board. Even if the problem is on a plug in board there are ways to troubleshoot and many people have successfully repaired a 990 without extender cards.

    since I started this thread three years ago, I have sill yet to find a set. I even went to the houses that custom make test cards. The connectors are the issue "unobtainium". I agree that there are ways for a hobbyist. by trial and error guidance, to make a repair. Possibly to get a radio working. BUT the issue is alignment after repair. The hunt continues.
