This is what I know, thought I knew or remember:
The front-end connected to the master DTE (I.E., *the* front-end) runs a version of RSX
called RSX20F
The DN60 software running to speak RJE/37xx/HASP to an IBM system is specially written
and not RSX based.
The DN20 software is or was called "MCB". Somewhere there is an email as to
what this means. I don't know if it is RSX based.
Back during Phase III
development (so probably early 1980), I was asked to create a snapshot of our current
development disk. I later found that this was for LCG in Marlboro. Looking at some of the
TOPS tapes at pdp-10.trailing-edge.com <http://pdp-10.trailing-edge.com/> it appears
that MCB makes use of the communication executive code used by RSX/IAS and RT-11 DECnets.
It also appears that MCB is RSX11S based - at least there’s a copy of RSX11S.TSK present.

I never heard of COPOS/11 and there is no mention of
it in any of the emails that I have preserved from the 80's and 90's. The Tops-10
NFT and related sources appear to have some special casing for it. That's of interest
because I don't believe the MCB could do DAP or had FAL.
I was wondering what ELAN meant?

I don't think anyone actually knows. But someone found some mention of it being some
kind of FE for TOPS, but it't not *the* FE, as far as I could understand.

COPOS/11
So what exactly is COPOS/11? Did I miss that in the original discussion? I think it
was said that COPOS/11 was the front end for TOPS-20, but AFAIK the FE for both -10s and
-20s is RSX-20F. Was COPOS some internal name for that, or is there another story here?
