Were there 2 things called the KM11?
The KM11 that I know is the maintenance unit, composed of a W130 and
W131 plugged together. It goes into a specially-wired connector on
some older PDP11s (e.g. the 11/45), controllers (e.g. RK11C) and
periperals (e.g. RX01).
I have a pair of real DEC ones, and a clone I built to do tests on my
PDP11/45 before I got the DEC ones.
