My TU10 is hurting.

It used to be so nice. But the dehumidifier hose got clogged while I was gone. The room filled with mildew. I came home and rushed to save my stuff, mostly successfully. The TU10 was affected, though. I don't know for sure if the dampness was the cause, but I'm guessing it was. Here are the symptoms: under rt11 5.00, it won't init a tape. used to do this w/ no problem. rt returns "output error on mt0:" The tape spins and tries to init, but after going back and forth a number of times, it gives up. So the mechanism and control logic seems fine. I've tried different tapes and cleaned and degaussed the head. No change. Jiggled all the cards in the controller and device section to 'assure' a good connection. Nothing. I even tried using an old copy of ROLLIN, just to see if it'd do a backup, but it moved the reels and instantly gave a FATAL DEVICE ERROR on MT0. Unfortunately, my xxdp pack is thrashed (moldy), so until I can replace it, I'm stuck with trial and error here... help if you can, please!
