Integer Basic was in the ROM on the II, AppleSoft on the II+.  The ROM the
changeset recommends is the  II+ one - so that's Applesoft running.  You can
also tell because the prompt is ']' - Integer Basic used '>'.  So you've got
floating point math there, bucko!

I remember that book well - it was quite a mind expander.  Given the funky
layout and randomness of information scattered throughout, it's no shocker
that Ted Nelson apparently has some sort of attention-span disorder.  The
biggest problem I recall with owning that book was that if you lent it to
anyone, you wouldn't get it back.  Which is what happened to my copy.

It's amazing what people used to do in 1 MHz machines with total memory size
of your average web page or JPEG file.....
