I *think* this had a CMOS cpu, and is related to the [[PDP-11/93]]....????
The '''PDP-11/94''' is the [[UNIBUS]]-capable twin to the [[QBUS]]-only [[PDP-11/93]]; both used the [[KDJ11-E CPU]] (with its [[Private Memory Interconnect|PMI]] bus, although with the [[main memory]] all on the [[Central Processing Unit|CPU]] card, the PMI was less important). The -11/94 added a [[KTJ11-B UNIBUS adapter]] to provide its UNIBUS, and had a custom main [[backplane]], the [[KDJ11 PMI/UNIBUS backplane]], to support it.

A PDP-11/94

The PDP-11/94 is the UNIBUS-capable twin to the QBUS-only PDP-11/93; both used the KDJ11-E CPU (with its PMI bus, although with the main memory all on the CPU card, the PMI was less important). The -11/94 added a KTJ11-B UNIBUS adapter to provide its UNIBUS, and had a custom main backplane, the KDJ11 PMI/UNIBUS backplane, to support it.
