Oh yeah... I forgot about that! One time I wrote a program to draw 
randomly positioned circles in random colours. After a few minutes of 
drawing, most of the pixels were in the "on" state, but there were weird 
squares of colour that changed every time a new circle was started.

I also remember saving several test patterns to tape, and eventually 
discovering which colour provoked which tone from the speaker... Jesus, 
I was bored as a child!

I've always wanted to know... why is the framebuffer arranged so 
weirdly? Like, as you load a picture file, rather than filling from top 
to bottom, it seems to fill every Nth line...
