Second, many/most of the CPU modules are -YA variants, and the "PDP-11
Field Guide" mentions that they would be part of a KH11-A. About the
only description I can find for what that is, is a single mention (in
PDP-11_PeripheralsHbk_1973.pdf) of the "large-system capability
option" related to the DT03-F Unibus switch requirements. Anyone know
what this is? I'm reasonably certain it doesn't matter for my needs,
but I'm curious.
The April 1983 Option/Module list (one of several at Bitsavers) says that a KH11-A is
"system expansion (latency reduction)". Not clear what that means. It says
that it is used with KA11, KC11.
