RT11 will run w/o an LTC. TTBOMR the stack limit register is not need for Single Job and the other RT11 OS variants. However a program could overwrite the vector area and cause an ungraceful shutdown. Make sure the jumpers on the KD11-A are set correctly for this configuration. Using an RL02 to boot RT11 should be okay as well. Jerry j...@ieee.org
