Does anyone know what the current status of this might be? I am
fairly certain Mentec didn't get this and I am not sure anyone
did. Did it merely die when everyone thought Mumps was on the

something DEC picked up along the way after Mass General let it
out of its cage?
I'm pretty sure it was a DEC product. For that matter, it was used as the foundation
for at least one DEC product.
When I joined DEC in 1978, the group next to mine (Typeset-11) was the Assist-11 product
team. Assist-11 was a turnkey product for phone company directory assistance, allowing
names to be looked up in a large (million or so entries) database quickly. I have a clear
memory that this was built on top of DSM-11.
Curiously, a data sheet I recently saw for Assist-11 says it runs on top of RSTS. I'm
puzzled by that, because my memory is that DSM-11 is an operating system all its own, not
just a language processor running on top of a standard OS like RSTS. Perhaps it was a
separate OS at first and over time it was turned into a language subsystem on RSTS? Apart
from running into the Assist-11 team once or twice around 1978, I never had any other
exposure to that or any other aspect of DSM-11.
