Observing Summary:

The TVguider would not guide.  Its coordinates seemed to be 
offset from those in the 2.4m manual, so that when moving it 
to a location away from the chip, it seemed to obscure it quite
a bit.  The software for TVguider worked fine, but it would not 
guide on any star and the stars drifted out of the box.
JHK grism was not working either.  It did not disperse and 
created a strange illumination pattern on the chip that was the
shape of the slit itself - but there was no light illuminating 
it.
