Searching for something else (and I must say that the google one is really quite poor compared to the original 8052.com search), I came accross my own puzzle posted quite a couple of weeks ago - and I could not solve it without looking at the rest of thread! I could not even remember it!

Try not to cheat and read only the puzzle (don't even look at the rest of thread's post's subjects) - can you figure it out, or do you remember it?
