[Simh] Which PDP-11 to choose

If I may interject a serious note...

The J-11 based simulators (11/73 and up) are the only ones that were 
verified against actual machine microcode. The 11/73 system was the only 
one verified against its board and system specification. The others are 
all derivatives.

I always debug with the 11/73. It has 4M memory, I/D space, and access 
to large disks via the MSCP controller.
