The '''KJ11-A Stack Limit Register''' is option for the [[KD11-A CPU]] of the [[PDP-11/40]]. The basic KD11-A implements [[PDP-11 stack limit|stack limit]] functionality, but at a fixed [[address]] (0400); installing the KJ11-A allows the address boundary to be set in a [[Central Processing Unit|CPU]] [[register]].

Physically, the KJ11-A is an [[DEC card form factor|extended-length]] single-height coard ('''M7237'''), which plugs into a dedicated slot in the CPU's [[backplane]].
