Yes, because KLH emulates the KL; the KL has the KLNIA (ethernet adapter) & a version of TOPS-20 that supports DECnet Phase IV. SimH only emulates the KS, and TOPS-20 dropped support for the KS before DECnet Phase IV.
All my comments are in the context of SimH and the versions of TOPS-10/-20 that it supports. > I > improved klh to use tap/bridge devices (much like currently present in > simh).
