This discussion reminded me of a very interesting series of incident
documented on the web pages linked to below. The problem was related to
control computers which were controlling exposure to patients which were
being treated with a particle beam from a linear accelerator. The title
is the Therac-25 Accidents, if you already are familiar with it.
I don't recall from having not reread this whether this was a PDP-11
instrument or not, however, but this certainly remindes me of this.

I was
wondering if anyone on the list had one of these machines and knew
what parts made the hardware a Gamma-11, as well if anyone had manuals
online that they might share
I have the manuals scanned, but they aren't on line yet, since it hasn't
been
a high-demand item.
