Basic lessons in English. These are for old PETs, which you can
recognise by the pokes that go to the "shadow" of the screen memory,
that is not present anymore in newer PETs. It's pretty funny though
from time to time.
Machine language lessons in German. Note that their load address is $0400
instead of $0401, presumably because they were saved from a BASIC 1.0
machine. Also note that there are two lines numbered 4. How can these be
loaded to a PET?
