Is AIS the same as AIDCS?

No. IAS (not AIS) is an RSX-11/D variant that intended to add timesharing
capabities to RSX-11/D. RSX-11/D was pretty much limited to fixed purpose
real-time and turnkey applications (such as Typeset-11) because of the
inflexible way in which it managed memory through "partitions". That term
also shows up in RSX-11/M, I think, but in /D it was quite rigid and not
suitable for situations where the applications to be run were not known
ahead of time -- as would happen in timesharing systems with programmers
using it.
