Two quick comments on this thread.

We have all heard of PDP_11's being used in nuclear power stations
which is SCADA when you come tight down to it but I had the opportunity
to run in to another use.  Many (about 40!) years ago I worked for
Martin Marietta (now Lockheed Martin).  I used to make trips out to
Denver for various projects. (Is Hans Brinker still there?)  In one
of the many machine rooms there was a small rack with a PDP-11 in it.
No one ever went near it and it just sat there quietly humming away.
One day I learned it ran the HVAC for the whole complex.

Was Allen Bradley the SCADA company that had a line of 6809 systems
some of which ran OS-9?  Or is my memory faulty in this.  Senior
moments become more common every day as I celebrate my 75th birthday
today.
