Interesting.  I never heard of Mini-RSTS before.  Looks like a marketing hack; it's basically just a standard RSTS-11 system, a close to minimal configuration.  All they had to do is slap a name of it and print a new piece of paper, and presto, the appearance of a new product.

On the other hand, "Micro-RSTS", which appeared much later, is a different item; it involved some (fairly modest) changes in the software and its packaging and installation procedures).
