memory map for RT-11 v 5

Mon Jul 25 15:34:12 CDT 2016

Is there a place where one can get RT11 disks for RL02?  I only have rt-11
5.3 and even with 64K I can't get my system to boot.  Everything so far
checks out, I am at a loss to determine the cause of the problem.  In simh
I can boot 5.3 on a PDP 11/20 emulated with 32K.  It must be my system but
I don't know what's wrong.  Diagnostics don't fail, or I can't get anything
clearly wrong.  I can load in programs from papertape just fine.
