I combed through this site and found the following in the meeting minutes
for 1997:

NYCNUG Meeting Minutes for July 10, 1997
.... Tom Deering went "to the video tape" and allowed us to see a close up
view of his Newton stylus to discover that there were particles of dirt on
it that was difficult to see with the naked eye. He also showed us that
simply using a cotton swab does not work in cleaning it. He was able to do
this by hooking up a video recorder to a microscope. He played the video for
us. Tom's stylus was made by Cross (800) 510-9660.

I could swear that back in 1998, there was a link to the photo accompanying
this note. Maybe Loren knows Tom Deering and could check on this?
