The LSI-11/2 (also known as the KD11-HA) is the later version of the LSI-11. It contains only the CPU, and nothing else; it is otherwise identical in functionality to the LSI-11, including the use of ODT, rather than the up-to-then conventional front panel
It is a dual board (M7270), using the LSI-11 chip set, and supports all the same options as the LSI-11.
These include the KEV11-A, for the EIS/FIS instructions; the KEV11-B, which provides EIS without FIS; and the KEV11-C provides a subset of the PDP-11 CIS (it also apparently includes the EIS, but not the FIS).
It likely also supported the optional KUV11 Writeable Control Store.
Note: The image in the "Microcomputer Products Handbook" (pg. C-18) is erroneous; the order of the chips (from the handle end) is, in fact, KEV11, Control, uROM 1, uROM 0, Data Path (per the KD11-HA print set); the order given in the Handbook is that for the LSI-11 (no doubt an image was re-used without checking).
