[Coco] Nitros9 and the 86 GIME again

[mmarlett at isd.net]

This is REALLY a bad case if true. All the more reason to move off the '86
GIME.

I don't advertise that I have extras, but I have about six '87 GIME
(TCC1014A) at Cloud-9. Please contact me privately if interested. Please
note that a PLCC tool is highly recommended to be used on the removal.
