The pictures of Space Invaders remind me of our school computer club,
where we had one cassette with that game, and it had a clever copy
protection. It only worked if you loaded it from the first (internal)
cassette recorder. The trick was that there was code in the first
cassette buffer, which got there because the program was saved with a
name of some 188 characters...

When loading from tape, the FOUND... messages show only the first 16 of
the buffer, so you never notice.

After I found out, I became the proud owner of another copy.
