That's correct, but it may be worth adding that for UK educational
customers it's possible to get Poplog direct from Sussex University at
an amazingly low price (#1,500 for a complete site licence when I last
saw the price.)
Also Integral Solutions Ltd give a minimum educational discount for
people outside the UK of 85%, and are always willing to try to help
educational customers with budgetary problems.
Finally I seem to recall that at some point someone at TCD acquired a
Poplog licence, so maybe all that's needed is an update from ISL.

If you install everything and leave all the default saved images,
demo programs, etc. I think it's about 60Mbytes for version 14.2. Almost
certainly V14.5 is bigger. But you can delete portions you don't want.
A huge amount of it consists of online documentation and demonstration
libraries. There's also several Mbytes of stuff provided in case you
have to re-link the system, but that's so rare it need not be kept
online. On the other hand, there are poplog users who will provide
things for your local library free of charge and that can easily grow
to many mbytes.

Prolog is one of the languages in Poplog, and Poplog runs under several
versions of Unix, and VMS. There's a fairly rich interface to unix
(including e.g. callbacks to C programs) provided via the pop-11 subset,
and the prolog can invoke that easily.
This includes all the X interface stuff that allows you to link in X
widget sets.
I hope that helps.
