[PDP-10]
I misread the manual. The extended addresses were 30 bits or about 4GB
which was plenty for that era, but the way they did it in 256K word
sections was still a kludge. In the original PDP-6/10 every
instruction could address all of memory. In extended mode you could
directly address only the current section, and everything else needed
an index register or an indirect address.

While this wasn't terribly hard, it did mean that any time you wanted
to change a program to run in extended mode you had to look at all the
code and check every instruction that did an address calculation,
which was tedious.
Hmm... would a simple recompilation have done the trick, or were there
also issues with integers being restricted to 18 bits, for example?
