M8189

The KDF11-B PDP-11 CPU for the PDP-11/23+ was implemented as a single quad card, the KDF11-BA M8189, using the same 'Fonz' F-11 chip set as the other KDF11 CPUs.

In addition to the basic CPU functionality, it included chip sockets for adding the KTF11-A (memory management) and the KEF11-A (FP11 floating point). The sockets can also hold the KEF11-B 6-chip carrier implementing the PDP-11 Commercial Instruction Set.

The board also contains sockets for PROMs (for booting and diagnostics), KW11-L line time clock functionality, and two asynchronous serial lines (using the standard 10-pin DEC pinout).
