I'm glad Gary Wunder finally found his mylar sheets. I, too,
used the Sewell drawing kit extensively. The kit contained a
clipboard with a rubberized surface so that the mylar would
pucker up as you drew the pen point across it. It also contained
an upward-writing slate. The slate was a one-liner with about 12
cells. It had rounded dots where the pits would ordinarily be.
You used the slate with a hollow-pointed stylus. You could move
the slate around and put a braille label at any point of a
previously prepared drawing so that the braille would appear with
raised dots at the site of the label. The hollow stylus is also
very useful for getting into a small space and engaging the end
of a dip switch so that you could flip the dip switch up and down
without disturbing the position of any of its neighbors. I
thought that this would be of interest to some of us.
