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.
