Apparently from all the confusion at PPCo, I acquired a copy of this
blueprint that was previously marked as discontinued since their last
catalog 1994-1995.  It came as a real blueprint copy meaning instead
of the background being blue it is black.  With today's technology and
using Linux, I was able to scan it in and do a reverse on the colors,
so the background is white and the blueprint lines are black.  This
can be found at
