   We have plenty of systems around here that are based on RT-11.  Just got   
   rid of the last PDP-8e in 2022 and replaced it with an Allen-Bradley PLC.   
   I expect the PLC to last as long as the PDP-8 did because that's what   
   it's for.   
      
   The embedded control world is not the IT world.  Embedded systems often   
   outlast their support and their manufacturer.  So you plan for it.
