KJ11-A Stack Limit Register
From Computer History Wiki
The KJ11-A Stack Limit Register is option for the KD11-A CPU of the PDP-11/40. The basic KD11-A implements stack limit functionality, but at a fixed address (0400); installing the KJ11-A allows the address boundary to be set in a CPU register.
Physically, the KJ11-A is an extended-length single-height coard (M7237), which plugs into a dedicated slot in the CPU's backplane.
