I thought TOPS20 used the same RSX20F as TOPS10.
The PDP11 that "controls" the KL-CPU runs RSX20F
attached to a DTE.
Additional PDP11:s either run the DN87/DN20 front end
code or the MCB (that was RSX based).
KA/KI had PDP11s attached to the DL10 and they run DN87x.
There is a PDP8 version think it was called dn91, that talks
to a DS10 IO-bus sync interface on the 10 to.
