OK, I just found online and purchased the following books:
Programming with RT-11 Vol. 1 Program Development
by Clinch, Simon & Stephen Peters
Programming with RT-11. Vol. 2 Callable System
by Peters, Stephen, et al.
Working with RT-11
y Beaumont, David, et al.
Tailoring RT-11. System Management and Programming Facilitie
by Clinch, Simon, et al.
Now I'm wondering if there are any other books on RT-11 available (besides
the actual doc sets) and if these books were worth getting?
