I think you are right, but my memory is fuzzy on all this now. IIRC with
the MIT/BBN pager modification, KA10's could run ITS or TENEX (aka twinex -
which was the Tops-20 pre-cursor ).
I'm 99.99% sure the BBN and MIT pagers are unrelated, even though they were
both built for the KA10 and around the same time. TOPS-20 and ITS paging are
certainly different universes.
