John-

Brian Patrick here has a stage drive system that is expected to provide
digitized coordinates from the light microscope to the probe. It is
apparently working, but I have not attempted to carry over numbers yet.
Also, we are easily using NIH and PhotoShop on the Macs here for image
processing from the probe. Ask Brian about both of these things. I hope to
get such info on our users group asap:

patrick@magic.geol.ucsb.edu

Thanks for the all of the info. I have Milton Person's stuff from
discussions earlier with him at Rice.
